The scene that greeted me was a far cry from the blood-soaked dungeon floor.
No rotting meat. No screaming. No monsters.
Instead, I lay in a wide, lavish room—spacious, well-decorated, drenched in soft golden light. A classic Western-style estate. The kind you'd see in some old aristocratic drama.
I stumbled out of bed, disoriented, my limbs oddly uncoordinated. Each step felt... off. My depth perception was warped, my balance shaky. Like the world had been resized.
No—I had been resized.
I was... shorter. Way shorter.
Reaching the door took effort. I stretched my hand up to grasp the knob, twisting it open with unfamiliar fingers.
Outside stood a girl—no, a teenager. Fourteen, maybe fifteen. Lavender hair, unkempt and hanging in uneven clumps. Her dull, deadpan eyes stared at me with a strange mixture of fear and politeness.
"G-grandfather wants to have dinner. Please come downstairs,shinji" she mumbled, her voice quiet and hesitant. Despite the expressionless face, I could tell. She was afraid.
...Wait. Did she just call me Shinji?
Lavender hair... lifeless eyes...
Hold on. Is that... Sakura? From Fate?
No. No fucking way.
That would mean—I've been isekai'd?
I mean, I was just brutally murdered by a dungeon boss and then swallowed by a purple void, so... maybe?
But seriously, Shinji fucking Matou? Out of everyone?
That scumbag? That irredeemable walking trauma machine? The guy's not even a monster—no, calling him that's an insult to actual monsters. He's filth. What he did to Sakura... ugh. No. Shame doesn't even begin to cover it.
"...Yeah. Okay," I replied dryly, watching her turn and descend the absurdly extravagant staircase. The whole estate—yeah, if I remember from the anime, it's like a mini castle. Rich, eerie, cold.
Closing the door behind me, I slumped down onto the floor and curled into a fetal position.
My mind raced. My heart pounded.
"Matou… Fuck, man. I'm so screwed."
How the hell am I supposed to survive this world? And her?
I can't stop thinking about her—about Sakura. That girl's living in hell. Not just because of Shinji... but because of me now. Because I am Shinji.
And she's technically my sister.
Even if she's adopted, that doesn't matter. I have to help her. Not just out of guilt, not just out of pity—but because I have to. If I don't, she'll break. Like in Heaven's Feel. And then I'll have to deal with that version of her—the monstrous one.
I can't let that happen.
Big brothers protect their little sisters.
And besides... I don't have mana circuits. I can't even do magecraft.
So what can I do?
God help me. I don't know.
But I have to try.
