The combat here moves like nothing else in the franchise, every punch lands with weight, every block telegraphs what comes next. The soundtrack doesn't just underline the action; it becomes part of how you read the fight, turning hand-to-hand into something that sounds as good as it looks. Three episodes is barely enough time, but the pacing knows exactly what to cut and what to hold, letting character moments breathe between sequences that most shows would rush.

The members of the Hiizumi Life Counselling Office leave for a much-needed break at a mountain hot spring, but trouble hits Sakura Shimachi while they are gone.

Shidou, adoptive father to Kana and her sister Mina, has to take on Rokkaku's formidable strength to bring her home. The three-episode OVA adapts the eleventh volume of the manga and mixes supernatural action, comedy and ecchi moments.
