Koushi Inuzuka is an intelligent high school student who aspires to become a public prosecutor. However, his family background poses a challenge to achieving this goal. His father, the head of the martial arts family, only knows one language: violence. As a baby, his father made a pact with his biggest rival to marry Koushi to their daughter. The union of the two bloodlines was supposed to produce Earth's strongest martial arts clan. In high school, Koushi is unaware of the arranged marriage and enters into a relationship with Momoko Kuzuryuu, an airhead loli martial artist who self-proclaims herself as his bride. However, their relationship is fraught with challenges, including Momoko's desire for sexual intercourse and Koushi's refusal due to her resemblance to his little sister and lack of knowledge about who she actually is. Additionally, a war has broken out between the martial arts families, putting Koushi in danger as numerous fighters seek to challenge or assassinate him. To make matters worse, Koushi suffers from fight phobia due to a traumatic incident from his childhood. It falls upon Momoko and her superhuman fighting skills to protect Koushi. The question remains whether the two sweethearts will survive the trials ahead of them and if Momoko will receive a baby from Koushi.
