Hana

Hana is one of the 4 girls Arashi entrusted to Ryouta to look after. Though not much is known about Hana, she is usually labeled a "bookworm" and knows quite a lot from her school in the Other World as well as books from there as well. It is implied that Hana has some kind of supernatural ability but this hasn't been shown that strongly yet in the series.

Appearance
Hana looks like an 8-year old girl like the others but has a dirty blond hair color and also wears the same school uniform from the other world as the twins do. She also wears glasses, which is the usual stereotype for smartness.

Relations with Others
Hana doesn't really have relations with others as she is always trapped inside of Dgem's dragon as a sex slave, as Dgem puts it to terms. However, she is usually one a person could turn to if they needed any information regarding anything supernatural.
