Someone was draining people's mana at school.
Many students had already collapsed, and since magecraft was meant to remain a secret, the authorities had no clue what was actually happening. To them, it was just another case of sunstroke, nothing more.
But Rin knew better.
She stormed back and forth in Emiya-kun's room, her arms crossed and a deep frown carved into her face. Every step she took echoed her frustration.
Archer, meanwhile, lounged lazily in his seat, watching her pace with mild amusement. Shirō was at the stove, cooking, because of course, she was the one stuck making dinner while these two schemed.
"This is being done by a Master and their Servant," Rin declared, her voice sharp.
Shirō turned from the stove, brow furrowing. "But who?"
"A Rider-class Servant," Rin answered. "Archer has been keeping an eye on them for the past few days."
Shirō clenched her fists. "We need to stop that bastard from harming innocent people."
Archer cracked open one eye, his expression unreadable. "Even if it means killing them?"
Shirō didn't hesitate. "I'm not naïve, Archer. Not everyone deserves to live."
For the first time, Archer actually looked startled. He hid it well, but Shirō caught the faint flicker of shock in his expression. Internally, he was shitting himself.
What the hell?
His past self—his Shirō Emiya—was supposed to be an idiot who wanted to help everyone and save everyone. But this... this realistic Shirō...
Was this because of the fusion with Artoria? Probably.
Rin ignored their tension and kept going. "Tomorrow, Shirō, you'll come to school with me. We'll investigate and figure out who's behind this. Archer will watch from the shadows."
Shirō frowned. "But I'm not a student of that school. I'm not Shirō Emiya anymore!"
Rin smirked. A smirk Shirō did not like.
"I have an idea you'll love, Emiya-kun."
Shirō gulped.
