Mariya is a first year student, who, while
dressed as a young girl is actually a boy in disguise. Though Mariya appears to
be a perfectly delightful young princess, he is in fact a sarcastic sadist who
takes great pleasure in making Kanako’s life a complete misery. He is the
grandson of the previous headmistress of the school and is always accompanied
by his personal maid, Matsurika, with whom he frequently trades insults.
