Kitsaku, known as Kitsu, is a generally happy person, but when she gets angry its hard to calm her down. When she's angry she tends to tear and start crying, even though she's not sad. She's a very emotional person.
Kitsaku's parents died in a house fire when she was 4, so she doesn't remember them. She was the only survivor from the fire. She went around the country to new homes within 5 years. When she was nine she went to an orphanage and met Katsumi. They became quick friends and we never seen apart. One day Katsumi got adopted and never came back. Kitsaku finally got adopted, and searched everywhere for Katsumi. Eventually she found her and now they live together in a small house.
