Maho Kazami is the younger sister of the main character, Mizuho Kazami, in the anime Please Teacher!. She has a youthful appearance, characterized by her blue hair and green eyes.

As a member of a family with ties to the Galactic Federation, Maho is deeply protective of her sister and initially disapproves strongly of Mizuho's relationship with the human teenager Kei Kusanagi. Her disapproval stems from a belief that a member of the elite Galactic Federation Observers, a title which Mizuho holds, should not marry someone she views as a primitive Earthling. This conflict forms the core of her role in the story, as she actively works against their union, even going so far as to attempt to use a character named Miruru to harm Kei. Her motivations are rooted in her close bond with Mizuho and a desire to protect her sister from what she perceives as a mistake.

Despite her initial hostility, Maho undergoes notable development as she witnesses the depth of the love between Kei and Mizuho. This forces her to relent and accept their relationship. However, even after her acceptance, her personality remains playfully devious. She shows a degree of affection toward Kei, such as stealing a kiss from him, but she is also not above using blackmail to get what she wants. Her key relationships are primarily with her sister Mizuho, whom she is very close to, and with Kei, who transforms from an adversary to a brother-in-law she enjoys teasing. While no specific notable abilities are detailed, her role highlights her determined and cunning nature within the dynamics of the Kazami family.
