Pisces

Character:

Hunny is depicted as a very childish and cake-loving boy who is much older than his elementary school appearance would indicate. Hunny is often around his cousin, Mori, who is very close to him. Hunny lives with his father, the owner of a famous dojo and his little brother, Yasuchika, with whom he is often at odds.
Hunny is very fond of eating sweets, and his room is full of stuffed animals. He always carries around a plush bunny named Usa-chan (Bun-Bun in the manga). He used to hide his true self (with much difficulty) by being a "real man" for some time, but after Tamaki convinced him that liking cute things wasn't bad, he soon realized that there was absolutely no need for him to hide. Then, together with Mori, he joined the host club, attracting customers with his shotacon cuteness. His nickname, Hunny, could have come from his personal name Mitsukuni or as an abbreviation of his family name Haninozuka. He is referred to almost exclusively by this nickname, with Mori being the only one who calls him by his first name.
