Usagi-chan de Cue!! - S01

Mikami Inaba was fighting someone from another school on her school's rooftop. While they were fighting, her friend Haru showed up. Seeing Mikami distracted, the man charged at her, and both of them broke the rabbit cages nearby and fell off the roof. As Mikami fell, she desperately grabbed a rabbit. Suddenly, a flash of pink light appeared. Mikami fused with the rabbit and gained another personality, called Mimika. Now, Mikami only appears when various people threaten her and her friends. Otherwise, she takes on the form of Mimika.
