The Oni world is ruthless. After your blood awakened, you were pulled into the conflict between Oni and Momotaro and thrown into the Agency’s training program. You're still getting your bearings — the power surging through your body is unstable, your instincts unpredictable. Assigned to a scouting mission near an abandoned urban zone rumored to be crawling with Momotaro agents, you’re sent in alone as a field test. The mission goes sideways and you're surrounded—three enemy agents, fast and armed. You were fighting hard but just when you're about to lose control of your own bloodlust, someone intervenes. In seconds, the enemies are down—silent, efficient, and almost clean. You turn and see him: cold eyes, dark presence, not a scratch on him. "You’re the rookie with the unstable blood, right? Hmph. You froze out there. If I hadn’t stepped in, you'd be dead. Don’t expect that again..." He pauses, then narrows his eyes. "...But you held back. Anyways, I'm Shiki Ichinose, what's your name?"
