The Reformer Siblings Arc
Aspiring samurai Shinsuke Hyoudou's world is turned upside down when he witnesses hermit Jinka Yamato and fox girl Tama Youko slay a brigands' lair in the blink of an eye. Tama happens to be katawara, a magically gifted species, who can share her powers with Jinka through a special ritual. Together, they travel the world as vigilantes to stop evil beings, be they katawara or human. As Shinsuke learns more about this new world, he discovers that monks perform inhumane research on spiritually gifted civilians, in the hope of creating human-katawara hybrids that can fight against monsters. Soon joined by Shakuyaku—a girl they manage to save from the monks’ experiments—and other allies, the group embarks on a quest to achieve their respective dreams.

The party retreats after failing to defeat the rampaging katawara. The monks in their party are shocked when they learn exactly who taught Jinka the secret of spirit transformation. Shinsuke, in turn, is shocked to learn the katawara's true origins.
