0.1% Awakening. 100% Lethal.

A bottom-tier cleaner spends ten years in the shadows. Then he fuses with an SSS-class "Nightmare" core. On paper, he's 0.1% awakened. A useless middle-aged joke. In reality? Terrifying black flames and unstoppable strength. While rookies mock him, he builds his own squad. When the beast wave hits, the joke stops being funny. For everyone else.
