Hina Tsuruno

She lives at the same home as Rin Namiki, Misa Aoi, and at least three other girls. Her mother Minato Tsuruno owns the house, and Hina does all the cooking for the residents.

When Rin is in need of members for her Jet Racing Club so that it can become an official club, she convinces Hina to join by offering her food.

Hina does not participate in the races, but she provides food for all the club members and joins them in getting a part-time job when the club was in need of money for a new part for the Orcano.
