Mai Kawakami (川神 舞 Kawakami Mai?) is one of the main characters of the Musaigen no Phantom World series. She is a second-year high school student at Hosea Academy, who has a special ability in which she fights the Phantoms along with her friends as a Phantom Hunter of Team E.


Mai is noted to be a beautiful teenage girl with a fresh young face. She stands at an average build and rather tall height. She has long, straight, sandy blonde hair which is usually seen being tied into a side ponytail using a big blue ribbon with free-hanging bangs that frame her face. She sometimes wears her hair loose, and it reaches down to her back.

Mai also has beauty marks under both of her purple-colored eyes. She is usually seen wearing her Hosea Academy school uniform for 2nd year female students.

Mai is noted to have large breasts, and a voluptuous figure.


Mai has a lively, upbeat personality, and she is very confident in her skills. She is rather active, fit and strong; often fighting the phantoms using only her legs and sometimes hands. Even as a child, Mai possessed great strength. She is very straightforward and she is the one that will do what she has to even if it’s a bit embarrassing,[1] but she’s also very determined to get into the phantom jobs. Mai is also very kind, somewhat motherly and protective of those she cares about, as she has even earned herself the nickname "Phantom-Hunting Mom".[2] She is very understanding of situations and can sympathize with others.

Mai is also very supportive of her friends but doesn't particularly like people with selfish and rude personalities. She is also very close with Haruhiko, but she does enjoy to tease him sometimes. Since she is very confident in herself and skills, Mai will usually take on opponents that she thinks she can handle by herself since she doesn't want to put her friends her in danger. But since Haruhiko works well with Mai, the two often ends up working together.[3]

Even though she lives alone, Mai has remained relatively cheerful. She relates to Haruhiko because they have quite similar pasts. She acts like a big sister to Reina, whom she deeply cares for.


What is known about Mai's background is that she is one-quarter Japanese, and she learned Chinese self-defense from her father.

When she was little, Mai stated that she was a shy and quiet girl, who usually kept her distance from her other classmates, but was later revealed to be false. As a child, Mai has always been lively and straightforward, similar to her personality now. Even as a child, she was strong. Even though she had trouble making friends, she became with two girls, and for some reason, she accepted playing with them and being their friends. Her two friends are now known as the two girl-phantoms, who waited for Mai for revenge, upset that Mai would always experiment fighting techniques on them. However, she later sealed those phantoms with Haruhiko, hoping that one day that she could fight them again.[4]

During her time spent with Haruhiko when he became a child, it is revealed that her mother is deceased.[5] She lives alone in her apartment, supporting herself through high school.[6]


Mai is the female protagonist of the series. At the start of the series, Haruhiko and Mai are the only members of the Phantom Hunter Club: Team E. They were the team who hadn't really earned much. Mai was usually seen finishing on Phantoms in the school whilst Haruhiko sealed them. They continued their daily routine until they met Reina, Koito and Kurumi who joined their team later on.


Mai's ability is called "Spirit of the Five Elements". Her ability requires her to basically rub different areas from her sides to her breasts to channel a specific element into her fists, using the classic Chinese elemental system. She specializes in close combat and her power consists on channeling elemental powers through her body, such as fire from her heart or water from her kidneys.


  • Her first name (舞) means "Dance".
  • Mai has the same voice actress as Sanae Dekomori from the Chuunibyou demo Koi ga Shitai! series, another anime produced by Kyoto Animation.
  • According to the memories Haruhiko Ichijo has copied she wore her first bra in fifth grade and has a bust between 90 and 100. Possibly 95.[7]
