In a brutal war between devils, hunters, and secret enemies, a mysterious girl named Reze has stepped into Denji's world, and he faces his deadliest battle yet, fueled by love in a world where survival knows no rules.

Denji has a simple dream—to live a happy and peaceful life, spending time with a girl he likes. This is a far cry from reality, however, as Denji is forced by the yakuza into killing devils in order to pay off his crushing debts.
