Takamiya Honoka finds himself caught between two powerful witches with very different intentions. His sister Kazumi and her friend Evermillion have cooked up a scheme that pushes the boundaries of what Honoka thought he understood about his family's magical connections. What starts as an ordinary day spirals into chaos when their plan kicks into motion, forcing Honoka to confront just how deep the supernatural world runs through his everyday life. The OVA doubles down on the series' blend of action and comedy, delivering the high-energy magic battles fans expect while leaning into the absurdist humor of watching ordinary situations get hijacked by witches. There's real stakes underneath the jokes, though, as the episode reveals more about the relationships between Honoka and those closest to him. If you connect with the main series' balance of supernatural conflict and character dynamics, this picks up that same thread without breaking stride. The animation handles both the bombastic spellcasting and the quieter character moments with equal care.
