Fujima Emiri

Ren's stepsister with an upbeat personality, and a fallen angel who clings onto her brother. Currently in her first year of school. The two are close enough that they can joke around with each other, but doesn't forget her special sister's privilege of being doted on. A long time ago, Emiri used to be a cupid-inspired idol, but decided to retire when urged to become a variety show idol. Having grown sick of the pure and simple life of an angel, she ran away from home. There she met Ren and grew fond of him, and decided to become his little sister. With Ren's parents constantly away on long trips, she and him are practically alone. Whenever Ren grows silent, she suddenly barges into his room, or sometimes digs around the tissues in his garbage -- Emiri is quite the busybody. Also, she can apparently inherit the name of Cupid thanks to her family standing, but absolutely refuses because she would "never want some lame name that sounds like mayonnaise". However, her arrows of love as a fallen angel are aimed straight at her brother.
