Tama wants to save humans even though she's a monster, Jinka hates them even though he's half-human, the show builds everything around characters who are fundamentally at war with what they are, not just external enemies. The first few episodes drag while it figures out who these people actually need to be. Once it does, the emotional weight stops being theoretical and starts breaking you, especially when it finally shows you why Jinka became what he is. By the end, every fight matters because you understand what each person is actually fighting for.
Tama is a katawara, a monster born into a world where her kind preys on humans. She breaks that cycle by swearing to protect people instead, driven by genuine love for the humanity she refuses to destroy. Her brother Jinka walks the opposite path: mostly human but consumed by hatred for the species that raised him. When a cowardly swordsman named Shinsuke crosses their path searching for strength, the three unlikely companions become bound by a far darker purpose than personal redemption. Across the war-torn Sengoku landscape, a conspiracy unfolds. Someone is experimenting on humans, forcibly transforming them into monsters through brutal means. What begins as scattered rumors becomes an undeniable threat that pulls Tama, Jinka, and Shinsuke into direct confrontation with powerful forces determined to remake the world's balance of power. Action erupts constantly as the trio fights their way through armies and loyalties fracture under pressure. The series balances visceral combat with character arcs built on contradiction: a monster defending humanity, a human despising his own kind, a coward seeking courage when the odds refuse to bend in his favor.
