Nagasumi is still trapped in the same ridiculous domestic sitcom, except now the OVA format lets the comedy breathe without padding. Each episode is a self-contained bit of controlled chaos: overprotective dads, actual animation that doesn't cut corners, new characters who slot perfectly into the existing madness. If you watched the TV series and thought "this works best when it stops overthinking itself," these shorts are exactly what you wanted.
Nagasumi's third year of high school brings no relief from the chaos. San and Luna's overprotective fathers continue their meddling ways, turning everyday school life into a minefield of yakuza drama and supernatural mishaps. Caught between his mermaid fiancée's family drama, Luna's relentless pursuit, and an endless stream of people needing rescue, Nagasumi finds himself perpetually one step away from disaster. These two standalone episodes introduce fresh faces to the cast while ramping up the comedy that defined the original series. The OVAs lean harder into slapstick situations and absurdist humor, with Nagasumi playing the exhausted straight man to an increasingly unhinged supporting cast. Romance simmers beneath the surface, but the real appeal here is watching one poor human guy juggle impossible circumstances with nothing but determination and a complete lack of personal space. If you found the original series' brand of romantic comedy chaos entertaining, these episodes deliver more of what made it work: commitment to the bit, rapid-fire gags, and characters who refuse to let anything as trivial as logic get in the way of their goals.
