Hinagiku Katsura Friends

Hayate's former classmate and yet another love interest. Nicknamed "Hamster" by Nagi during a humorous Toradora reference.

Hayate is a combat butler for the Sanzenin family with a debt of about 150 Million Yen that he has yet to repay.

Izumi is a student and the younger fraternal twin sister of Kotetsu Segawa.

Maid of Nagi Sanzenin with a slight crush on Hayate. Often plays the voice of reason compared to the other two.

The young, short heir to the Sanzenin fortune who happens to be in love with her butler and rescuer, Hayate.

Risa is the head of the disciplinary committee at Hakuō Academy.

Sakuya Aizawa is a cousin of Nagi and from Kansai. Like Nagi, Sakuya is very rich and has a similar personality — loud, arrogant, abusive of servants, and unwilling to accept defeat in anything.

Teacher at Hakuō Academy and older sister of Hinagiku. Obsessed with money and booze, and largely in debt because of that.
