Based on a seinen manga by Shinobu Ohtaka, serialized in Young Gangan.
Koushi Inuzuka is a smart high school student who aims to become a public prosecutor. Unfortunately for our good guy, he was born into a martial arts family whose head (ie his father) only knows one language: violence. When Koushi was still a baby, his father made a pact with his biggest rival to marry Koushi to his opponent-turned-friend`s daughter. The union of the two blood lines is supposed to bring forth Earth`s strongest martial arts clan.
Skip forward: Koushi is in high school, oblivious to the marriage arranged for him at his birth. Enter Momoko Kuzuryuu: sugar bomb, airhead, loli martial arts artist and Koushi`s self-proclaimed bride (the strongest on Earth, no less). Her wish for sexual intercourse meets with Koushi`s square refusal as he has absolutely no desire to get it on with someone who looks like she could be his little sister, not to mention that he doesn`t have the foggiest idea who she actually is.
Meanwhile, a war has broken out between the martial arts families. For Koushi, this means that numerous fighters are out to challenge him. As if that weren`t bad enough, our protagonist also has a fight phobia due to a traumatic incident that took place in his childhood. Now it`s up to Momoko and her superhuman fighting skills to protect her "husband." Will the two sweethearts survive the trials and tribulations ahead of them? More importantly, will Momoko get her way receiving a baby from Koushi?
