Six shorts stapled to the BD volumes, and they know exactly what they are: bath steam, dorm hijinks, and about four minutes of actual plot smuggled in while you're distracted. Episode one does the homework the TV run skipped, filling in character background before it drops you into "Then The Two Go to the Learning Dorm." After that it's Irori getting careless at the open air hot spring, Charlotte and Frey trapped in the fearsome bathroom, and Nadeshiko Akabane turning up in a midsummer night's dream that has no business hitting as hard as it does. There's real foreshadowing buried in here for anyone who caught it, and the final one actually lands an emotional beat. Nobody's pretending this is essential viewing, because it isn't. But if you finished the series and just wanted more time with Raishin and Yaya, five minutes a volume is a fair trade.
Raishin and Yaya return to the Academy's dormitory for a collection of standalone adventures that shift between comedic chaos and suggestive situations. Each episode spins its own story: from awkward dormitory mishaps to unexpected encounters at hot springs, bathroom disasters with fellow students, midnight escapades, private lessons that blur professional boundaries, and a beach day that spirals into absolute pandemonium. The format prioritizes humor over plot continuity, leaning heavily into fanservice and the chemistry between Raishin and the various women orbiting his life. Physical comedy drives most scenarios, with characters finding themselves in increasingly compromising positions through circumstance rather than intention. The tone remains deliberately light and self-aware, never taking its setups seriously. What you're getting here is pure supplementary entertainment for existing fans of the series. These OVAs exist specifically to give devoted viewers more time with their favorite characters in low-stakes, high-embarrassment situations. If you appreciate lighthearted ecchi comedy with zero narrative weight, these episodes deliver exactly what they promise without pretense.
