These bonus episodes return to Rito Yuuki's chaotic household, where alien princess Lala lives alongside her younger sister Momo. Rito still cannot choose between Lala and his longtime crush Haruna. That makes him the center of Momo's scheme: marrying Lala would one day crown him King of Deviluke, so Momo sets out to gather every girl who likes him into a single harem. The shorts string together body-switch mix-ups, childhood memories, and the trouble the plant-girl Celine causes around the house.
