Sweet Assassin 5 - or 'I am willingly not playing this game correctly.' (Fateverse, SI)
Tohsaka Rin was a girl with a drive and a plan. Well, more of the former than the latter actually.
Ever since Zelretch had mentioned that the surviving Master of the Holy Grail War was on the move around Europe, Rin had been wondering if that was a push to investigate the matter. At first, that wasn't something she entertained. If Zelretch was not concerned, then it meant this wasn't a good enough reason to interrupt her studies.
Then the Wizard Marshal suggested this Master had actually summoned another Servant and... yeah, this was a bad thing. A Master with a Servant was bad enough, two was just a sign that this may be a build-up for more. What if the man was trying to build an army? That would make him unstoppable.
And that is if she was through the very simple question of: "How the fuck did he manage to summon two Servants and still live with the upkeep?"
It was either a matter which involved an abnormal individual, or said individual did something inhuman to attain an elevated magical input to support multiple Servants at once. Rin would have just taken to whine to Zelretch during her studies, but she found the allure of personally checking this far greater.
Maybe she was also going nuts because of Luvia's constant teasing and bullying. Older and wiser the Tsundere had gotten, but the blond-haired ojou-sama was good at grating her nerves into fine dust. The trip to France also sounded like a good way to skip studies and relax a bit. A studious scholar Rin was, but she was also a growing girl that was still recoiling from second-hand rejection.
Like, if Shirou was so quick to shoot down Sakura, she should have known that she had no chance with him too. Frustratingly enough, she had been tempted to make common front with her estranged-now-reunited sister to share the moron, but things took them elsewhere and Rin was no longer sure Shirou was even a viable lover.
Maybe she had seen through the veil, or maybe she was just too disappointed in him and herself to go forward in that path. Which is why she found this investigation to be as confusing as infuriating.
Because the bastard she was spying upon ever since he arrived at Lyon was actually having sex with his Servants. Within consent. Hell, she was quite tempted the tallest of the two girls was actually pushing to be dominated after seeing her behaving in a mighty attitude and then meowling in pleasure while getting pleased by her Master.
The worst part was the Master. Rin called him a bastard, but not for fucking his Servants. Oh no, Rin was furious because the utter fool was actually a softie like Shirou. Well, a more mature softie than Shirou at that. Shirou was withdrawn from going too far, but the young man she was spying and 'ogling' at times was clearly a good one.
Pity he is a potential enemy.
That didn't stop Rin from getting some 'solo action' while seeing him claim both of these Servants. One of them was even mini-Rider. Part of Rin wondered how Sakura's Servant would react to this.
Possibly embarrassment with some arousal.
A few days went by, and then a scene worthy of some concern unfolded. It was morning, Rin was keeping track of the Assassin Servant known as 'Stheno' shifting out of bed, walking up to the hotel rooftop and... setting up a Seal Array. Rin's younger self would have called it a ruse from the Master to trick her, but she was quite sure the Servant was acting on her own initiative.
Especially when she got some of the runes wrong. Scowling at the potential fuck-up that was soon to happen, Rin decided to take a risk and 'assist' the group for a proper summoning. While this didn't bode well, it was better than risk it with an untested rune circle that could do far worse than summoning a Servant.
So, as Stheno walked back down to the hotel, Rin moved to the rooftop and started to rewrite the array to some extent. With her warm cup of coffee keeping her sanity up and her mind focused, the girl was soon through the incorrect sections. She left just in time to see a very annoyed Master leading the two Servants to the rooftop, glare at the circle and then sighing loudly before getting the ritual going.
All should proceed smoothly by Rin's predictions... but then Rin realized, as she felt her throat wanted more of the sweet coffee, that the cup she had been sipping from had been neatly left within the circle without her noticing. Her blue eyes widened in dread and the summoning went on to unleash...
A blonde version of herself. With bigger tits?!
It was painfully early in the morning, and Stheno was almost done.
Usually, it would be her Master creating the array, but after seeing him do it just once, Stheno was sure she got this one right. The chalk used had been the same he used. The runes were correct, the chant meant for the summoning was knowledge she had through the 'grail' despite it no longer being a thing and... She knew it was only a matter on how to convince her Master to get it going.
Yes, there have been plans to delay this until they were in a safer position, but Stheno was bored- and impatient. She was a Goddess! Of course she would feel the case of her missing sibling to be noteworthy enough for her brattiness to rule against her own logical judgment!
So, as she was done working on it, she walked up to their room, glared at Meduseless for snatching the wonderful place that was their Master's chest, and proceeded to slap the man awake. Softly so, obviously, she wasn't in a bad mood towards him.
"Ghh, Stheno?"
"I wanna try again," She flatly stated. "Please."
The 'Please' was delivered with the flattest shade of that flat tone, leaving John frowning at Stheno for a good few minutes. Enough for Medusa to stir awake and look between the two with pure confusion on what was behind this standoff.
"It's not a safe-"
"I have the array already drawn in the rooftop."
John's frown deepened at the interjection.
"Uh?" Medusa asked sluggishly, with her sister smiling.
"We are trying to summon again."
The girl perked. "Oh?"
"Despite the fact we are not fully in a safe spot."
"Oh," Medusa nodded in agreement, deflating slightly.
"We're going to summon Euryale for sure, though."
"Oh, oh~!" Medusa hummed giddily, her mood soaring at that and outmatching any common sense mustered by their Master.
Tired, and yet fully awake, John led the group to the rooftop and started the ritual. Everything went according to plans, with her blood being good enough of a catalyst to muster the right Servant. But instead of an Archer, a Lancer came through.
And as the light lessened, Stheno was utterly defeated by the appearance of a figure that was not her sister. Far from it. Taller, blonde, red eyes and fat breasts. There was a shared wave of surprise within the group as the new Servant introduced herself.
"Lancer at ready, I am the Goddess Ereshkigal using a body for my manifestation and... what?"
It was at this point that the blonde realized that her Master was giving her an odd look.
"I don't want to say this as if you were unwanted but... we kind of used a catalyst that shouldn't have summoned you."
She frowned, turning around and glancing at something. A cup of coffee. One that wasn't meant to be there as far as Stheno recollected. Which meant that...
"Someone is spying on us," The Assassin blurted out, eyes widening. "Someone is spying on us!"
Everyone panicked, and while Ereshkigal thought this was fine for an Holy Grail War, Meduseless started to explain what was going on as they all rushed to the hotel room, packed their things and left as fast as possible through the bus waiting in front of the hotel.
"As I was saying-" John started to bring up, only for Stheno to facepalm, feeling humiliated for what had just happened.
"N-No comment. I can't believe I..."
For some reasons, she could tell this was punishment for wanting things done fast and rushedly. And as they left towards a new safer location while explaining the situation to Ereshkigal, the four failed to realize one thing.
Sipping from a cup of warm chocolate just a few seats behind them, a certain female exorcist smiled happily as the situation was as fortuitous as she had been praying for.
Let's see what we can do with Mr. John.
AN
Rin making a mess, Ereshkigal being the best result of said mess, and Caren getting the things she wanted landing close to her lap. Next time, Ereshkigal gets a bit of 'affection' in the forms of... actually wholesome situations. Plus she peeps on lood stuff.
