我間乱～ＧＡＭＡＲＡＮ～

Naoyoshi Washizu asks his father to find a warrior strong enough to defeat his siblings in a clan succession contest. Gama Kurogane accepts the challenge after the request reaches his remote dojo. He enters the Unabara tournament, where different schools of combat clash for political power. Gama's allies and opponents reveal the brutal rules behind the struggle for the clan. The early chapters center on swordplay, martial schools, and a fight over inheritance.
