Mai is a second-year student at Hosea Academy with a special ability that lets her fight phantoms alongside Haruhiko Ichijou. She's fairly tall and notably busty, with long straight sandy blonde hair usually tied to the side with a big blue ribbon. She has beauty marks under her left eye (though the anime depicts them under both eyes).
Her personality is what makes her stand out—she's lively, popular, kind, and genuinely caring. She's also incredibly active and determined, relying mainly on her legs when fighting phantoms. What fans often note is how straightforward she is; she'll do whatever needs doing even if it's embarrassing, and she's laser-focused on making phantom-hunting her career.
Mai's half Japanese on one side and learned Chinese self-defense from her father. Her special ability is called the "Spirit of the Five Elements." It works by rubbing different points on her body—from her sides to her chest—to channel specific elements into her fists using the traditional Chinese elemental system. She's built for close combat, channeling elemental powers through her body: fire from her heart, water from her kidneys, and so on. She specializes in hand-to-hand fighting, making her a powerhouse in direct confrontation.
