Fukushuu Kansuisha no Jinsei Nishuume Isekaitan THE COMIC

The bitter winter cold that claimed his sister’s life five years ago never truly left Kosuke Kurono’s heart. She was taken from him in the most brutal way imaginable—raped and murdered—and from that frozen moment onward, revenge became his only reason to exist. Every waking hour, every calculated step, every drop of blood he spilled was in service of that single, burning goal. When he finally cornered her killer and exacted his vengeance, Kurono found himself hollow. With no purpose left to anchor him, he turned a blade upon himself, ready to end the hollow silence of a life without her. But death did not grant him oblivion. Instead, he awoke in a world of swords and sorcery, reborn with a gift beyond mortal reckoning: the legendary Black Magic once wielded by the ancient heroes who shaped that realm. Yet power alone meant nothing without hope—and hope arrived in a whisper from the divine: his sister, too, might have been reincarnated into this same world. That fragile possibility reignites a fire he thought had died. Now, armed with forbidden sorcery and an unyielding resolve, Kurono traverses uncharted lands, battles monsters, and unravels mysteries of the past, all while searching for a single soul among millions. In a world that owes him nothing, he clings to the one thing that still matters—finding her, before the shadows of his former life consume him entirely.
