A guy who wants a normal life gets a fiancée whose entire personality is "solve problems by hitting things harder." The show knows exactly how funny this collision is, and it never wastes it. By the time you realize you actually care about these two idiots making it work, the comedy has already done the heavy lifting, and the final arc proves it earned every laugh it got.
Koushi Inuzuka is a bright high school student who wants to become a public prosecutor, despite being born into a martial arts family led by a father who settles everything with his fists. When Koushi was a baby, his father agreed with his greatest rival, later a friend, to marry Koushi to that man's daughter, uniting their bloodlines into the strongest martial arts clan on Earth. Koushi knows nothing of the arrangement until Momoko Kuzuryuu appears: a sugary airhead who looks young enough to be his little sister, calls herself his bride and claims to be the strongest fighter alive. She wants to consummate the marriage, and Koushi flatly refuses, having no idea who she even is. Meanwhile, war has broken out among the martial arts families, and fighters start coming after Koushi, who has been afraid of fighting since a traumatic childhood incident. Protecting her "husband" falls to Momoko and her superhuman skills in this action romantic comedy.
