A high school guy who wants to be a prosecutor gets saddled with a bride trained to solve every problem by hitting it. The comedy lives in that collision, the gap between his careful logic and her fist-first martial arts family philosophy. Two episodes means this special is pure romance escalation with no filler, just the weird intimacy of watching two people figure out they're actually stuck with each other. The ecchi works because it never pretends to be anything else. This is the show you watch when you want something that knows exactly what it is and doesn't apologize for it.
Koushi Inuzuka just wants to focus on his studies and become a prosecutor. His problem: he comes from a family obsessed with martial arts, and when he was a baby his father promised that Koushi would marry the daughter of his rival-turned-friend, a match meant to create Earth's strongest fighting clan. That daughter is Momoko Kuzuryuu, a bubbly, airheaded martial artist who declares herself his bride and wants to have his child. Koushi flatly refuses, since she looks like a little sister to him and he has no idea who she is. Meanwhile, a war between the martial arts families sends challengers after him, and a childhood trauma has left him afraid to fight, so Momoko has to protect him with her superhuman skills. These two special episodes were released on DVD as episodes 23 and 24, and they mix comedy, ecchi humor and romance.
