She hates the rape but grows to love and understand Shirou over time.

Prompt: If Merlin was going to solve the seventh singularity for Chaldea then he was going to demand proper compensation, and there was only one form of it he was interested in. Doing something idk what yet was a very taxing feat afterall, and it did force him to risk his life! Sating his lusts on the female servants of the singularity.

Prompt: Rin Tohsaka summons the Archer class servant EMIYA at the start of the Fifth Holy Grail War, but this version is a bit younger and less experienced. He broke up with his Rin a decade ago and has longed for her body since. Seeing the cute younger version of her as his master, he indulges on his desire for his master that hasn’t been sated in a long time. Starts out as non-consensual but with his years of experience bringing her pleasure, he knows exactly how to bring her total bliss and have her loving it and begging for more.
Characters: Rin Tohsaka, Archer Emiya

Characters: Mandricardo/Ritsuka Fujimaru (Female)
Prompt: Rather than Aphrodite’s mental attack mixing up memories and inciting anger, she takes a different approach to incapacitating foes- drowning them in so much pleasure they can’t move. Ritsuka is pleasured by many of the Greek Servants of FGO, and can only break free by fucking all of them unconscious.
Characters: Ritsuka Fujimaru (Male), Andromeda, Medusa, Euryale, Stheno, Astraea, Europa, Artemis
Prompt: Qin-Shi Huang puts Han Xin in charge of interrogating and torturing Koyanskaya, who he believes is Daji despite her denials. He has a different method to say the least, choosing to use her for his pleasure to get answers from her and punish her.
Characters: Han Xin/Koyanskaya
Prompt: Rather than falling in love with Ophelia, Napoleon sets his sights a little higher, on Queen Skadi herself. She is more reciprocative of his advances and the two have loving sex.
Characters: Scathach-Skadi/Napoleon Bonaparte
Prompt: Mash upon learning she is a Demi-Servant of Galahad in Camelot is properly inducted into the Knights of the Round. Of course, by that I mean she is gangbanged alongside Artoria Lancer and Mordred by Lancelot, Tristan, Gawain, Percival, and Bedivere when they return to Chaldea.
Possible follow-up: The Round Table Knights of Avalon le Fae are properly welcomed by the Male Knights of the Round
Prompt: Cu Chulainn Berserker does not take kindly to the attempted ambush by Nero, Geronimo, Billy and Robin Hood. He kills Geronimo, and Billy, but Robin Hood escapes. He keeps Nero as a toy to use for his pleasure. Rape and treats her with zero respect. She is just a toy for his gigantic monster cock.
Characters: Cu Chulainn Berserker/Nero (Bride)
Possible follow up: Elizabeth tries to rescue her friend and is also broken by Cu. Medb wants what he’s giving Nero and submits to being a toy.
Prompt: Kirei Kotomine wants to know what is so special about Irisviel von Einzbern that it would allow Kiritsugu to find his humanity and not be as empty as he was. When he takes her hostage rather than killing her and turning her into a grail, he opts to first indulge himself in her body, despite lacking lust for her, believing she could be the key to finding meaning. He admits she is the best fuck he’s had, but can not see why she would lead to that change in Kiritsugu and kills her afterwards without regrets, still feeling nothing towards her, and no closer to finding purpose.
Characters: Kirei Kotomine, Irisviel von Einzbern
Prompt: Shirou Emiya is a female, and that changes Illyasviel von Einzbern’s approach to this Holy Grail War. Her berserker is a monster with a 24” cock, and that gives her a terrible idea on how to get revenge on her “sister” she can simply have her servant break Emiya on his cock. Rape and mind break almost instantly.
Characters: Heracles Berserker/Emiya Shirou!Female
Prompt: In a world where Ritsuka Fujimaru dies with the rest of the Master candidates, Cu Caster tries to get Olga Marie and Mash through Fuyuki, but with a lack of mana and Master candidates, they have to turn to other methods to make sure they have enough magical energy to survive the singularity. A mana transfer. Cu Caster can’t say he’s upset with how things turned out, Olga Marie was a great fuck and that Mash girl was eager even if she wasn’t as sexy.
Characters: Cu Caster (Odin)/Mash/Olga Marie
Prompt: Gilles de Rais has a dual purpose in using the grail to create a new Jeanne d’Arc who wants revenge. He also wants one to love. The one who comes out is Jeanne Alter but one completely addicted to Gilles de Rais and his hideous body, against all common sense.
Characters: Gilles de Rais/Jeanne Alter
Prompt: There was only one way for Saber Alter to tell which Moriarty was good and which was evil. The evil Moriarty was much more brutal during sex, no matter how much he tried to hold back and the good one would gently caress her and focus on her pleasure. For the safety of her master, she would interrogate Moriarty and fuck him until she knew which version this was, it was only for the safety of her master, and not because both Morairty’s were incredibly skilled with their cock and brought her pleasure, the likes of which she had never experienced before. How did she know that? It wasn’t at all important, thank you very much.
Characters: Saber Artoria Alter/Moriarty
Prompt: Christopher Columbus Final Ascend is him with two bunny girls on his lap. Artoria Ruler and Scathach (Technically his ships but close design wise). This is the story of how he broke them on his cock and made them into his NTR sluts who will do anything to be fucked by him. His next target is the fuck bunny herself, Koyanskaya.
Characters: Christopher Columbus, Artoria Ruler, Scathach, Koyanskaya
Prompt: Touko Aozaki has a different way of using Beowulf to break Aoko. His monster wolf cock in Aoko’s pussy, whether she wants it or not. But the plan might’ve backfired a little, after getting his dick wet, he needs more and turns his sight on his master.
Characters: Beo/Aoko, Beo/Touko
Prompt: Nasu went out of his way in Mahoyo to tell us that Beo is capable of shifting his gender to fit his ideal partner, after being defeated by the ordinary Soujuurou, and parting ways with Touko, he goes to Soujuurou to be his new master. With his growing feelings of submission to Soujuurou, he becomes a her and gives her fuckable body to Soujuurou, declaring him her master and submitting to him in bed.
Characters: Beo/Soujuurou
Prompt: Shinji Matou flees when Cu Chulainn turns on Kirei and kills him, but he doesn’t flee for long, or run into Gilgamesh. Instead, he returns after gathering his courage to see Rin still tied up, and while Shirou is occupied with his future self, he has his wicked way with her body. Non-consensual that her body responds a little to but she never really wants it to continue or enjoys it much.
Characters: Shinji Matou/Rin
Prompt: Noel just wants to take something from Ciel, it doesn’t matter what that is, she just deserves to feel some of her pain. She wasn’t an idiot- that much of one anyways, she could tell that Ciel had feelings for Shiki that went deeper than the mission. But she also knew Ciel wouldn’t admit to them and that left her with an opening. She would take Shiki for herself and force Roa to manifest by using her body to pull him out. He wouldn’t be able to resist taking her blood, and she would have the chance to kill him. She could take something from Ciel, get revenge on Roa, and complete the mission all at the same time! A triple win for her! There’s just one problem with her plan: Shiki isn’t Roa and she finds herself breaking on his fat cock.
Characters: Noel/Shiki Tohno, Ciel/Shiki Tohno (Implied)
Possible follow-up: Dead Apostle Noel/Shiki Tohno
Prompt: At the end of Heaven’s Feel Shirou was left without a body, his body destroyed by the Grail. Rin Tohsaka and Sakura Matou had sought various puppet masters in their pursuit of a new body for Shirou’s soul. The most they had found after years of searching was a used puppet body tuned to someone else. But, after years of searching, Rin had found the sealing designee, Touko Aozaki and convinced her to meet with Shirou Emiya about a new body. The two of them leave Sakura in Fuyuki (Now married to Shirou) and go to see Touko. Touko meets with Shirou in private and coordinates the design of his body, after he admits to her in private that he has a reality marble. Touko does not charge them cash for their services, instead demanding Shirou enter her service for a year. Rin and Sakura agree against Shirou’s initial protests, not willing to rob him of a body forever out of impatience and selfishness. Touko initially plans on using Shirou as a runner and incredibly useful agent with his arsenal of Noble Phantasms, and the opportunity to study his reality marble. Touko instead finds herself falling for Shirou’s charm. And when he awakens with a foggy mind from the body transfer (The murder of his temporary vessel), Touko sees him naked. She can’t resist his 13” penis and steals him away from his fiance, Sakura, taking him as her own for more than the one year he is indentured to her. This summary needs to be rewritten.
Characters: Shirou Emiya/Touko Aozaki, Sakura Matou
Notes: Fucking depressing as it would be less seduction and more Shirou falling back into being a sword instead of a person.
Prompt: In Mahoyo it is revealed that Astral Bodies don’t have a clearly defined form, but can shift to suit the whims of their master. When Gordes Musik (Goredolf’s father) summons the flatchested Elizabeth Bathory in Apocrypha, his desire for eye candy and a sexual partner causes her to become a big-chested bimbo slut.
Tags: Gordes Musik/Elizabeth Bathory, Bimbo, rough sex
Prompt: Ciel is a curry aficionado. She loved curry in all forms and had gone to every restaurant she could find that served curry. Yet, the best curry she had ever tasted had not come from any of those restaurants- it was a hand cooked meal that she had stolen a bite of from Caren. After weeks of begging for more, Ciel finally has the chance to meet the chef and get her fix of perfect curry. If she complies with Caren’s demand to whore herself out to the chef- Caren’s boyfriend.
Tags: Ciel/Emiya Shirou/Caren Hortensia
Prompt: Gudaguda 2022/2024. Kukochihiko’s sword drains the intelligence of its victims and turns them into a mindless beast. All I’m hearing is a canonical bimbo sword. He uses it on Okita Alter. Maybe Iyo too idk.
Tags: Okita Alter/Kukochihiko (Wolf guy), maybe more idk, bimbo stuff
Prompt: Musashi and Shirou fluff post “A Pair of Reckless Swordsman”. As much smut as it is just cute relationship stuff, and the story of their grail war.
Tags: Musashi/Shirou, sequel
Notes: Alternate option is that Musashi does have to leave after the war and winds up back at Chaldea in Arc 2. When she finds Muramasa in the Olympic Lostbelt, Musashi won’t hear a no and fights to get her boyfriend back in control of the body and with her. Probably involves her agreeing to "betray" Chaldea and cut down Atlas. I would not be killing Musashi against Chaos. (This is the version I'll do when I do it)
Prompt: Shirou from UBW winds up in the past during Fate/Zero. He convinces Tokiomi to eliminate Zouken and take Sakura back from the Matou. Tokiomi was reluctant in spite of the horrible shit Zouken is doing to her, because the Tohsaka’s only have one crest, so only one daughter can inherit. Except… Shirou Emiya also has a Magic Crest- a Tohsaka one. The one he received from Rin so he could fight Gilgamesh. He just had to transfer it to a Tohsaka so that it could be inherited by Sakura and she could have a place as Rin’s sister. The problem? To transfer a crest to someone without the same blood- or from someone outside of the same bloodline, one had to use a tantric ritual. He obviously was not going to be asked to fuck a five year old Sakura, or even the seven-year old Rin… But there was another Tohsaka that he could transfer it to… Tokiomi’s wife… Aoi Tohsaka. Tokiomi was willing to give us his daughter to increase their chances at reaching the root, giving up his wife was hardly a line he wouldn’t cross. Perhaps it should’ve been because Aoi Tohsaka really liked the feel of Shirou Emiya’s cock, and the person he was. She maybe wouldn’t mind if Rin and Sakura had a new… a better father. Okay, she would mind it very much, she wouldn’t be able to live if Shirou was not in her bed every night.

Prompt: Jason was trying to recruit a new group of Argonauts to replace the old one that doubted his brilliance. Medea Lily was skeptical that he would be successful in his recruitment pitch, and did not want to see her Lord Jason displeased. So she took things into her own hands, offering her body to a few male Servants of great power in exchange for them joining the Argonauts. Arjuna Alter, Mephistopheles, and an Edison/Tesla threesome.
Tags: Medea Lily/Arjuna Alter, Medea Lily/Mephistopheles, Medea Lily/Tesla/Edison
Prompt: Unspecified servant loves her (Unspecified) Master, but her Master does not have adequate Magical Circuits to supply them with Mana. She wanted to marry her master, but she could barely even stay materialized during the war, let alone after it. So she would have to find an alternative source of mana to win and stay with him forever. She would not let herself prey on the lives of others but... there was another option. To stay with her master, she would betray them. By sleeping with dozens of other guys regularly to get the charge she needed. It did not matter if they fucked her better than her master, she would still only ever love her master.
Tags: Cheating out of love, gangbang?, idk this is very not fleshed out. No clue who Master or Servant should be either. First thought was Medea but no justification for her not using a leyline or any caster really. Ideally should be someone without circuits as Master?
FULL LENGTH STORIES WITH AS MUCH IF NOT MORE PLOT THAN SMUT (Skip to the bottom for more short form smut that spoils JP)
Prompt: Arcueid is first killed by a different person with mystic eyes of Death Perception- the Assassin Class Servant, the First Hassan. He’s the servant of Zouken Matou. Her regenerating body is found unconscious by Shirou Emiya, who takes her home to try to nurse her back to health. While Arcueid is sleeping in his home, Hassan comes to finish the job, having realized she had escaped before he could bring his master there for her to bite and grant immortality to. He tracks her down to Shirou’s home, and while she is unconscious attacks. Shirou by pure luck manages to detect him, and attempts to fight. He loses instantly, his hand getting sliced clean off. Shirou panicking unknowingly manages to force a summoning using Arcueid as a catalyst for it- he gets the Lancer Class Servant, a True Ancestor(adjacent), Yu Mei-Ren. Said servant manages to beat back Hassan. When Arcueid wakes up, she finds that Shirou is missing a hand, and recognizes Avalon within him. She recognizes that he saved her, and was hurt because of her. Being the inner sea of the planet personified, she had no trouble activating Avalon within him and triggering his regeneration. She sees that he has a servant who was able to fight Hassan and asks for shelter for the time being. Shirou accepts and then some as he promises they will eliminate Hassan together. Arcueid finds herself falling for the distorted human as they work together and grows to love him. She fucks him and possibly drags Yu Mei-Ren into the depravity with her.
Characters: Arcueid/Shirou Emiya, Yu Mei-Ren? Not sold on Yu's role as the servant.
Prompt: The Holy Sakura War. Sakura Matou being the vessel of the lesser grail has consequences. Every servant summoned shares a face with Sakura Matou. And a core love for her Senpai. They all want Emiya Shirou and won’t let him say no. Their masters often get dragged along. First chapter is probably just Shirou’s servant, Kama? BB is probably Sakura. Follow up would likely involve the other Sakura Five, Parvati, Martha, Rin, Caren, Illya, and potentially more.
Characters: Shirou Emiya/Sakura Matou, BB, Kama, Parvati, Meltryllis, Passionlip, Kazuradrop, BB Dubai
Notes: Starts same as of FSN with Shirou nearly getting killed by one of the Servants (Melt probably) and saved by Rin and her servant (Probably Kazura?). Shirou summons Kama when Melt comes back to finish the job. Kama drives her off and immediately wants to fuck Shirou. Shirou can’t resist the more mature version of his kouhai and falls into bed with her. He is more dominant than either of them expected. Full war is people falling into his bed. Master servant pairs are likely: Kama/Shirou, Sakura/BB, Melt/Caren, Bazett/Parvati, Rin/Kazura, Illya/BB Dubai, Luvia/Lip.
Prompt: Typical Shirou in Chaldea story, but as just a field agent enforcer role rather than Master because he's not Ritsuka and no one else can be them. Would bullshit that he can Rayshift because Avalon or something. All the girls would be temporary and encountered throughout the cannon story. Sex would be a supporting aspect to solve conflicts, not just oh he fucks Jeanne Alter into giving them the grail or whatever. Pretty much only "enemies" he would fuck as enemies are Artoria/Rin/Sakura faces. Would go through all of FGO and inevitably wind up too long and ambitious. Would follow canon pretty closely because there's not really room for deviation where they win, and basically just serve as an excuse for me to be like, hey Olga states the goal of the Foreign God in the first chapter, etc. First two chapter outlines below:
Shirou is met in the middle east by Lev Lainur and Rin Tohsaka who convince him to join Chaldea. Rin mentions that she had discussed this with Marisbury for years leading up to his death and they pitch it to Shirou as a chance to save the world without worrying about secrecy or a sealing designation. Lev swears that Chaldea has no interest in abusing his reality marble or Noble Phantasms outside of combat. Shirou is not "Rayshift compatiible" or capable of using their summoning system but he can survive thanks to Avalon and works as a safety measure. He is not planned to be a Master, but the enforcer and field agent backing up the B Team who lacks mages with the skill in combat of Team A so they're solely reliant on servants. Because Lev asked him to go deliver something to Da Vinci right before the Master's entered the coffins, Shirou is not in the room when the explosion takes place and as such survives. He runs to the control room and somehow is "randomly" rayshifted back home to Fuyuki 2004.
Progress through Fuyuki. Shirou realizes he will have to be the one to face both Archer and Saber, and thinks things are doomed if the Saber is who he expects it to be (Artoria). Olga when Shirou explains that he lacks the reserve of Magical Energy to hold up against both servants nerrvously offers to transfer him some of her magical energy... When Shirou asks if she means through transplanting circuits/crest, Olga flushes and gets annoyed at him for trying to have sex with her, but it's exactly what she meant. Shirou fucks Olga way better than he needed to for the ritual and Olga is now in love. The ritual also does not work as Olga is already dead and can't transfer her circuits. Shirou suddenly hopes that Saber is exactly who he was aftraid of it being.
Tags: A lot of stuff, but main pairing would be Shirou/Ritsuka (Female obviously). Their first fuck would be near the end of Arc 1, and they wouldn't be together together until like Olympus so... Way too fucking ambitious.
Prompt: I actually wrote 9,000 words of this one over a year ago, but it's going to naturally be very light on smut. I also haven't touched it since then because not one shots is a lot harder to write, and that's very very plot driven. Shirou sees Archer and Lancer duking it out while he cleans the dojo. They see him and Lancer goes to eliminate the witneess. Same as the usual. Except when he's cornered, Shirou desparetly clings to life and tries to find a weapon. Lancer is about to impale him through the chest when Shirou instinctively projects a copy of the same spear Gáe Bolg into his own hands. Lancer toys with him for a bit as Rin and her servant watch silently, Rin paralyzed and unsure of what to do. Finally, Lancer gets bored and stabs Shirou in the heart. Rin's servant urges her not to save him, since it's obvious that he'll be a master if she does, given what he just showed, but Rin ignores her Archer and tells him to pursue Lancer while she fixes this. She saves Shirou as per normal. Shirou cleans up the floor when he comes to and heads home. Lancer meets him there to finish the job. Shirou projects a more solid copy of Gáe Bolg this time. Lancer kicks him wall of the shed. Shirou stands up and traces another copy of the spear. Lancer drives him into the ground- both of them landing right on top of the faded summoning circle. The circle flares to life as Shirou fights to his feet again. Two artifacts calls out to a servant- Avalon and the weapon in Lancer's hands. Gáe Bolg since Lancer is also standing in the circle. Lancer shoves Shirou out of the circle again by impaling his thigh with his spear. Avalon loses the servant war with Shirou exiting the circle and Gáe Bolg gets to send out the call. The previous owner of the cursed spear responds- Cú's teacher, Scáthach (As a Caster). She trains Shirou to be a warrior capable of finally granting her wish and killing her.
Tags: Shirou/Scáthach, the original draft had Shirou becoming a Dead Apostle for reasons I won't spoil. There would be very very little sex in this one.
Prompt: Shirou in the Fourth Holy Grail War cause time travel shenanigans with the Grail being destroyed. Origin of the Aoi prompt above from like two years ago. He is sent back in time from UBW where he doesn't actually know Kiritsugu was in the 4th war, how bad the Matou are, or that Illya is his sister. Would have him give up the crest to save Sakura once he eventually learns of her situation and end up crippling himself before the inevitable Gilgamesh confrontation. His first appearance in the war would be the battle at the docs and recklessly charging Gilgamesh which puts... a lot of eyes on him. Including Dead Apostles (Avalon Healing Factor is mistaken for their regeneration) and very high people in the Clock Tower as projecting NPs deserves a sealing designation. Shirou and Kiritsugu would clash a lot about collateral.
Tags: No fucking clue what the pairing would be if there was one. Aoi and Artoria are the most likely options but... shrug. Very half baked idea.
EVEN MORE HALF-BAKED LONG FORM IDEAS FROM A WHILE AGO:
Prompt: Rin uses her command spell to do something other than make Archer obey her when he is being obstinate. She thinks he is being a brat with the whole not knowing his name thing and demands he tell her. He claims to be Emiya Shirou... Suffice to say that Rin does not approach her rival Master or her Servant the same way knowing who he becomes.
Tags: Rin/Shirou, maybe other stuff.
Prompt: Shirou is the one to summon Archer... Idk where to go from there other than murdering Shirou but...
Prompt: Instead of summoning EMIYA, Rin summons EMIYA. The father not the son as her assassin. An assassin who doesn't posses a single weapon capable of killing servants... as even his noble phantasm (Thompson Contender) with it's origin bullets can only harm a mage by destroying their circuits. What is that supposed to do against King Arthur? Rin, the girl who hates watching people die more than anything, has to fight with a servant who can only win by killing the Masters. And two of those Masters happen to be his children...
Tags: Probably Rin/Shirou but haven't thought of it in a while. This would be zero Kiritsugu, but he would have only vague recollections past being the Magus Killer because that is what his legend is. Same shit as Dantes not really being post salvation despite that being his ending.
Prompt: Somehow, it's Shirou not Shinji who loses their fight in UBW and is forced to go crawling back to the church. Terrified of what Shinji will do to Rin and Sakura without him able to protect them, Shirou pleads for a second chance. Kirei thinks it would be hilarious to give Shirou a new servant- Gilgamesh... you know right after Shirou got their bride killed... surely that will end well?
Tags: Not sure on pairing, maybe female Gilgamesh or Rin/Sakura both.
Prompt: Shirou raised by Gilgamesh fic. Basically Gilgamesh recognizes Avalon within Shirou while he is in the hospital and is the one to adopt him. All so he can groom him to eventually summon his bride back into the world. He would not be kind and Shirou would probably be close to a slave but idk.
Tags: Probably Shirou/Saber, maybe a threesome with fem Gil, or just a full harem because Gilgamesh is pro-polygamy (As long as he's not the one sharing)
Prompt: After another failed attempt at rescuing Illya, Kiritsugu is ready to give up on saving his daughter and go home to die with Shirou. That was the plan until he saw Shirou project a working copy of one of his mystic codes in order to cheer him up... and it wasn't disappearing? He knows he can't save Illya, but the traitorus part of his mind wonders if his son can. If he wields Shirou as a sword then is his daughter unreachable? If Shirou can duplicate any mystic code, then the answer is no. He tests the limits of Shirou's ability and tries to go back to being a mercenary with his failing body, all with the intention of dragging Shirou into war zones so he can see and duplicate hundreds of mystic codes. He tells Shirou that the goal is to save his sister, and gives Shirou a choice on if he wants to fight to save her before starting his training by fire. Shirou being Shirou, agrees without a second thought.
Tags: I have tried 100 different configurations to try to make this idea go anywhere, and no matter how much I like it, haven't found a path to having a real story that actually writes when I try. Probably won't be done, but wanted to share the idea. Feel free to steal it.
Prompt: Shirou summons the one servant who desperately wants to save Shirou against Lancer, the corrupted fusion of Angra Mainyu and Irisviel von Einzbern as the Avenger class servant. Illya is really really not happy.
Tags: Shirou Emiya/Irisviel von Einzbern/Illyasviel von Einzbern. Maybe more because Iri wants grandkids.
Prompt: Illya summons a Berserker in the 5th Holy Grail War, but it's not Heracles. Instead it's a very distorted version of Shirou Emiya driven mad by his insane ideals to save everyone. (Think Nightingale in FGO).
Tags: Probably Shirou/Illya but maybe harem or just not Illya shrug. Half baked ideas are half baked.
Prompt: Bladeworks Shirou is summoned as Saber of Black in Fate Apocrypha taking the place of Siegfried. He doesn't like his master, hates most of his partners, and finds himself sympathizing with Amakusa's cause rather than his own. (Could he be Berserker of black instead, madness enhancement fits given suicidal tendencies to do anything to save people and not plan at all).
Tags: Shirou Emiya/Fiore? (Could also be Jeanne or Mordred)
Prompt: The grail being destroyed has strange side effects, rather than giving Gilgamesh a mortal body, it binds his spirit origin to the only other survivor of the Fuyuki Fire. A defenseless Shirou. Or the one where Shirou is a Gilgamesh Pseudo-Servant
Prompt: Shirou summons Scheherazade, the Caster whose wish is to not die and avoid risking her life. She is all too happy to let Shirou protect her and doesn't push back when Shirou tries to stop her from fighting.
Tags: Shirou/Scheherazade, basically Shirou is forced to do everything himself.
Prompt: Sakura stays over the night Cu attacks and Shirou summons Saber. Medusa is there to play defense, maybe changes his summon idk.

Prompt: Sion’s Alter Ego in Paper Moon existed to give her a chance to be a friend to Ritsuka. Maybe, it wasn’t quite the Ritsuka she knew- a hollow and lesser version, even. Sure, she might be in the body of a child, but she was going to take full-advantage of the situation to indulge in all of Ritsuka. She might have to compete with a God of Love who desired to be loved in return, but that wasn’t going to stop either of them from taking all of the Ritsuka Alter since they could not have the real thing. Sion had always been bi anyways, so the more the merrier.
Characters: Sion/Kama/Ritsuka Fujimaru Alter Ego (Male)
Prompt: Shiny Star is a ploy that is meant to grant one’s greatest wish if it is entirely unique. Had Kinomi stumbled upon the play just two days earlier his wish likely would’ve been different, more selfless, but after seeing the usually antisocial Alice bathing nude in the Hot Springs in the middle of the night, Kinomi had been unable to think of anything but her. He wanted her to be his loyal slave, only craving his cock and worshiping him as a God. For anyone but Alice, that wish wouldn’t be unique, but Alice had seen so few men in the last five years to be craved by anyone else in the same way. And the few men she had spoken to all treated Alice with respect and valued her independence, even the ones who lusted for her. His wish was unique and so it was granted. Kinomi is happy with the result to say the least.
Characters: Kinomi Housuke/Alice Kuonji
Prompt: With Monte Cristo no longer able to clean up the Wastehole of Ritsuka’s mind after Avenger left, that job fell to some of the other dreamer servants. They all took different methods, but Lady Avalon thought the method she and Kama had found was the most fun.
