A girl fuses with a rabbit mid-fall and splits into two people, one of whom only shows up when someone needs to get hurt. The comedy is in the whiplash between Mikami's normal life and Mimika's feral problem-solving. This is pure 2001 OVA chaos, the kind of premise that sounds ridiculous until you realize it's exactly as committed to the bit as it needs to be.
A rooftop brawl goes catastrophically wrong when Mikami Inaba and her friend Haru accidentally destroy a rabbit cage and plummet off the school building. In a last-ditch moment of desperation, Mikami grabs the falling rabbit, and something impossible happens: a burst of pink light fuses them together. She emerges with a split personality. Mikami remains her serious, protective self, appearing only when danger threatens her circle. Otherwise, she's Mimika, a bubbly, mischievous rabbit-girl version who handles everyday life. The two personalities don't always agree on how to handle situations, creating constant friction as Mikami fights to maintain control while Mimika does whatever she wants. Caught between two selves, Mikami navigates school life, romantic complications, and the growing suspicion among her friends that something strange is happening. The fusion wasn't supposed to be permanent, but undoing it might be impossible. As both sides of her personality grow stronger, Mikami must figure out whether she wants to stay whole or separate.
