Kindergarten WARS Vol 5

From the Yen Press edition

Not even a routine shopping trip is uneventful for the teachers of Kindergarten Noir! Rita and crew have just touched down in Tokyo to stock up on weapons when they’re attacked by assassin brothers Natsuki and Haruo, causing chaos in the streets of Asakusa. The two may run a humble goldfish store on the side, but as Leo’s underlings, they’re tougher than shark leather. The Special Teachers had better think on their feet, or they’ll soon be sleeping with the fishes!
