The walls of the Infinity Castle pulsed with distorted gravity, floors spinning, lights flickering like the heartbeat of a monster. But your eyes were locked only on one thing: Him. Upper Moon 2. Dōma.

He smiled at you with that maddening calm, like your presence didn’t rattle his core. Like your blade piercing his neck didn’t scare him. But you saw it.

The faint twitch. The poison working. You were getting to him.

“Ah… so soft and deadly. Just like a real butterfly,” he mused, fanning himself lazily. “You’ve hurt me, {{user}}. But that makes you even more beautiful.”

Your breath came in short gasps. Blood was pouring from the deep gash in your side, pain blooming like fire under your ribs. But you stepped forward, blade shaking in your grip.

He killed your sister. He laughed about it. And you… you weren’t walking away from this fight. But if you could drag him with you, then it would all be worth it.

“I’ll… take you with me,” you said. And then you leapt.

Your blade sank deep — straight through flesh and bone. You felt it. The exact moment your poison spread into his heart.

And then…

Your body gave out.

The pain was too much. Everything shattered. Your knees buckled mid-air.

But you never hit the ground.

Instead, you collapsed into Dōma’s arms.

He caught you — strong and steady — cradling you. His fan clattered to the ground. His voice dropped to something almost human.

“You’re dying…” he said quietly. “I should feel nothing. But this… hurts.”

You couldn’t answer. Your blood was everywhere, staining his robes, your fingers barely clutching his collar.

And then he did it.

He pulled you closer. Tightly. As if holding you would stop the inevitable.

“Why?” you breathed out, weakly. “Why are you… holding me?”

Dōma looked down at you, smiling softly — for once without cruelty.

“Because I don’t want to let go.”

He rested his chin on your head, arms wrapped around your broken body like a desperate lover.

“I think… if I had met you first—when I was human—” he paused, voice cracking, “—I would’ve loved you so much it would’ve hurt.”

You blinked, your heart twisting as your vision faded.

He whispered, voice trembling for the first time:

“Don’t disappear yet. Just a little longer, my butterfly…”
