Description
Mika began existence as a rabbit born on September 15, 1984. A neighbor originally owned her but entrusted her to Gorō Mutsumi, believing he would provide the care and attention she needed, especially given her susceptibility to loneliness. Gorō named her "Mikazuki" after the crescent moon visible the night she came to him. Her death occurred during a period of isolation when Gorō left to care for his sick grandmother; he returned to find her deceased and buried her under a crescent moon.

Reincarnated as a Senior rank guardian angel, Mika's assignment is to protect Gorō. She manifests physically as a female appearing 17-18 years old, standing 155 cm (5'1") tall with waist-length purple hair styled in twintails resembling rabbit ears and red eyes. Her appearance features an orange color motif. Her measurements are B:84/W:56/H:80 in Season 1, changing to B:86/W:56/H:85 in Season 2. She commonly wears school uniforms or outfits incorporating rubber bands.

Mika possesses an outgoing, hyperactive, and attention-seeking personality. She often engages in flamboyant or sexually suggestive behavior to attract Gorō's affection, driven by autophobia stemming from her death and a persistent desire to become his romantic partner, fueling constant fantasies about their relationship. Her traits include being talkative, selfish, pushy, strict, quick to anger, and bossy, particularly towards other angels. She frequently admires herself in mirrors. Despite these tendencies, she exhibits protective instincts, especially towards children, and has aided fellow angels, such as helping Nana reunite with Gorō.

Her interactions frequently involve arguments with Ayumi (turtle) and Akane (fox), reflecting historical rabbit-turtle-fox rivalries. She dismissively refers to the eldest guardian angel, Yuki, as "mother." Mika views her connection to Gorō through a lens of romantic destiny, believing they will "fall in love and live happily ever after," despite no evidence of reciprocal feelings. Her efforts to impress him often involve imposing her fashion preferences.

Mika's hobbies include gazing at herself in mirrors and fashion, with magenta as her favorite color. Her astrological sign is Virgo.
