Right now, Illya and her mother represent an odd pair—a legal loli and an illegal MILF.
It all feels... a bit spicy somehow. Me likey!
Even putting aside the time-traveling Illya, Irisviel is only a year older than the "normal" Illya.
A one-year age gap between mother and daughter... only in the Nasuverse.
"What's up?" Rin glanced at Souta.
"Nothing. Let's go. We need to deal with the 'Caster' pair ASAP. If we let them run loose, Fuyuki's kids are in danger."
Souta pushed aside the impure thoughts.
"Alright, I'll lead the way."
Rin had Lancelot dematerialize, then led Souta to a typical suburban home in southeastern Fuyuki.
Standing at the front door, Rin explained:
"This house had a family of four—middle-aged couple, teenage daughter, and a grade school son. Ryuunosuke Uryuu broke in, killed the parents and daughter, painted a summoning circle in their blood, and saved the boy to offer to the demon he's calling."
"...WHAT!?" Souta froze.
"Relax, that's from the original plot."
Rin smirked mischievously, clearly enjoying his startled reaction.
"I caught him when he snuck in. I used a suggestion spell to make him think he killed them. Right now, he's probably painting with chicken blood I provided."
"...I swear, the longer we hang out, the more you mess with me."
He almost blurted: "Are you sure it's chicken blood and not your—cough, never mind."
"Come on, let's head in."
Rin pushed open the door, continuing:
"Once he summons his Servant, it'll be time for him to exit stage left."
They didn't plan to steal the Command Seals and summon a new Servant.
The timing of Ryuunosuke's summoning in the original was tight—Seals and Gilles appeared almost simultaneously.
Also, Souta didn't want to summon a new Servant.
The Holy Grail was now purified and usable, and he planned to kill Servants to make a wish.
If he summoned one he liked, it'd be awkward to kill them later.
Ryuunosuke Uryuu was a twisted psychopath.
He obsessed over death—the color of arterial spray, the warmth of internal organs, the screams of despair—to him, it was all more "real" than low-budget horror movies.
In the living room, Ryuunosuke was artistically splashing chicken blood over the walls.
He approached a bound and gagged little boy, enjoying the fear in his eyes as he stared at the imagined corpses of his family—all hallucinations crafted by Rin's magic.
"Hey, kid, do you think demons are real?"
Ryuunosuke, like a lunatic, spoke to the air:
"They call me a demon in the papers. But really, isn't that weird? I've only killed a handful—one bomb could beat me in a second."
Souta and Rin stood nearby, coldly watching his delusional monologue.
Rin's eyes glowed faintly—she wasn't crafting illusions, but projecting Ryuunosuke's own inner fantasies.
"I want to slap him." Souta muttered.
"Don't. Break the spell and I'll have to start over." Rin warned.
Ryuunosuke, increasingly animated, rambled:
"Now I'm summoning a demon! But if he really comes, I'm not prepared. What do I do, have a tea party? Hey kid, if he shows up, wanna be sacrificed? Maybe you'll get eaten or torn apart. Great experience, right? Definitely worth it—ow!"
Pain suddenly struck Ryuunosuke—a glowing red emblem appeared on his hand: the Command Seals.
Immediately, the chicken blood sigil began to glow.
From within, a robed figure emerged, bathed in eerie phosphorescence—a man with unnervingly smooth skin and eyes full of madness, reminiscent of Munch's "The Scream".
Gilles de Rais—once a heroic French general, now utterly corrupted.
Souta seized the chance, swiping Ryuunosuke's Seals away and transferring them to himself.
Rin ended the spell, and Ryuunosuke, regaining clarity, stared in confusion.
"Summoner, who calls me to this world as Caster? State your name."
Gilles scanned the room, eyes landing on Souta.
"My name doesn't matter."
Souta raised his hand, issuing a command:
"Caster, by this Command Seal, I order you—
summon your Sea Demon and kill this man."
Gilles widened his eyes, startled.
But Command Seals cannot be defied—he summoned a monstrous Sea Demon.
A foul-smelling mass of tentacles and fangs appeared.
Rin, holding her nose, stepped back.
The Sea Demon ignored her, lunging at Ryuunosuke, devouring him amid horrific screams.
As silence returned, Gilles faced Souta:
"Master, such a minor matter. There was no need to waste a Command Seal."
"Well, I'm rich and reckless," Souta smirked.
"And the Sea Demon's here for a reason."
"What reason?" Gilles asked.
Souta raised his hand again:
"Caster, by this Command Seal, surrender and stand still."
"By this second Seal, command your Sea Demon—eat yourself."
With both Seals spent, Gilles froze in shock.
The Sea Demon obeyed, tearing Gilles apart with tentacles and fangs.
Through agonized screams, Gilles stared at Souta like he was insane.
"You summoned me just to kill me!?"
Moments later, Gilles de Rais was eliminated—the first Servant to fall.
Souta incinerated the Sea Demon with divine flame, leaving only ash and scorched air behind.
