The isolationist Akane clan, made up of a group of girls mostly made up of young Kunoichi in training, has a code that everyone must adhere to: since men are dangerous beings, they are forbidden to deal with. Kunoichi Tsubaki, the leader of the so-called Dog Squad, is an excellent apprentice with a bright future, but she has started to feel a strange feeling in her heart ... when the subject of boys comes up.
