Japanese name:

服部 半蔵

Hanzo Hattori is Sen's servant and head of the Student Council police, wearing a maid's outfit and glasses. It is hinted that she has deeper feelings for Sen and may be a masochist longing for her abuses. Her weapon is a double-bladed pole that can split into two individual katana, and she can shoot a number of shuriken, kunai or any throwable material under her skirt. Her glasses allow her to detect an individual's power level.
