Zerozaki Kishishiki no Ningen Knock

A family known for unbreakable unity, the Zerozaki Clan ranks third among violent organizations for their combat effectiveness when protecting their own. Kishishiki Zerozaki is a member who uses a nail-studded bat as a weapon, which he names "Seamless Bias (Foolish Praise)." He was assigned a routine mission but was required to take Hitoshiki Zerozaki along for training. Instead of proceeding as planned, Kishishiki finds himself targeted by a skilled strategist and a violent opponent.
