A third-year member of Tenbi, she has been brainwashed by Kamigami and is a major antagonist in the Hime Kagura arc. She is very greedy for money and sweets, and despite her appearance, strong enough to knock Azuki around. Before her participation in Kamigami, she was one of the Four Pillars of Tenbi.
Yata - Hoshii's maken is a zone-type that manipulates luck. Every event of bad luck that Hoshii encounters is converted to good luck and stored in Yata; the worse the event, the more good luck stored. Hoshii can then withdraw good luck whenever she wishes. The range of her ability is a 150m radius around her.
