Shio Kobe

神戸しお, Shio Kōbe, Angel, the Moon

Shio Kobe is a young, innocent girl who lives with Satou Matsuzaka in their apartment. She loves and cares for Satou deeply, but often remains blissfully unaware of Satou's endeavors aside from Satou's necessary attendance in school and work, as she is not allowed outside of the apartment.

Shio is a kind and innocent girl who tries her best to work hard and watch over the house while Satou is away at school and work. She routinely greets Satou whenever she returns home and is always genuinely happy to spend time together with Satou. Shio believes that both she and Satou need to stay together, otherwise they would both be broken and incomplete forever.
