Episodes 23 and 24 on DVD are based on Shinobu Ohtaka's seinen manga, which was first published in Young Gangan. The plot traces the life of Koushi Inuzuka, a diligent high-school student, who aspires to become a prosecutor. However, Koushi is born into a family of belligerent martial art masters who believe that aggression is the only language that can be understood. In a move to establish the ultimate martial arts clan, Koushi's father makes arrangements for Koushi to marry the daughter of his once-rival friend. Koushi has no knowledge of the arranged marriage when we fast forward to the present day. Momoko Kuzuryuu, an inane girl with martial arts skills, and a sweet tooth for sugar, claims to be Koushi's betrothed. However, Koushi has no interest in Momoko, who looks like his younger sister and is unaware of who she is. In the midst of the chaos, a feud between the martial arts families ensues, with Koushi having to fight to defend himself against several opponents. He is, however, plagued by a phobia of fighting due to an unpleasant occurrence in his past. Despite this, will Momoko's superhuman fighting ability be enough to protect her "husband" from harm? Furthermore, can they survive the impending battles? Above all, amidst all this drama, will Momoko's desire to have a baby with Koushi finally become a reality?
