此花 ゆか

A first-year student at Saika Girls' Academy. Yuka is Nana's classmate, and both live in the same dormitory. She has a sunny disposition and usually smiles, even when upset. Her real name is Kazami Yuka (風見 夢歌), the deceased older sister of Kazami Sora. She once lived as a Tamabito, but now she is happily departed to the afterlife with the aid of her brother. Yuka occasionally appears at Sora's bedside and in his dreams while he sleeps. Sora, on the other hand, does not always remember the encounter when he wakes up the next day.
