The world is divided into two factions: humans and monsters called
katawara. Despite being a katawara, Tama loves humans and vows to
protect them from evil, even if it means fighting her own kind. Her
stepbrother Jinka, however, hates humans, despite mostly being one. The
siblings are joined by a cowardly swordsman named Shinsuke, who wants to
learn how to become strong.
When the group uncovers a plot to experiment on humans and transform
them into monsters, they vow to defeat whoever is behind it... Even if
it means battling an entire army of warriors.
The people they meet, places they see, and creatures they battle will be
legendary!
