Reiko Maguchi (間口 冷子, Maguchi Reiko?) was an antagonist of Mahou Shoujo Site Sept.


Reiko was a light-skinned woman with shoulder-length black hair that is tied in a ponytail and light-colored eyes or dark-colored eyes.

She was seen wearing a white dress-shirt along with a tight black skirt.


Reiko seemed to be a desperate woman, seeing as how she was the one who humiliated Tsurara Takahashi by spreading her pornographic photographs because she was jealous of Tsurara's and Kuraki's relationship, later it was also shown that she was also emotionally unstable as seen in her battle against Hyoka Nagatsuki and Isoko Anjou.

Reiko also shows no remorse and even takes pleasure in messing with her students' lives, being her prime motivation in tearing up love letters and stealing their valuables and has even shown to disdain and even outright hate her students, however, she's shown to also have outstanding acting talents as she initially showed and portrayed herself as a meek, helpful, concerned and kind teacher to her students and coworkers.


It should be noted that Reiko hasn't actually experienced any misfortune in her life.

She "hung" out with Kuraki and it is safe to assume that they were each other's sexual partners until Tsurara Takahashi has caught Kuraki's attention.

One day, while looking through her students' lockers, she found a bracelet, after putting it on, she found out that it had magical powers. She was originally looking through love letters in the student's locker when she found the stick.



Reiko can throw shards of ice at her opponents and can also summon ice from her hands to float to have the upper hand in battle. She can also resist the effects of the Electric Drill while summoning ice from her hands. She can also create ice around her hand and sharpen it, to greatly injure or kill her opponents.This Stick was Originally handed out by Juuroku to an Unknown Magical Girl before Reiko stole it from the girls school locker before she could receive it properly.


  • The name Reiko means "cold" (冷) (rei) and "child" (子) (ko).
  • Reiko's surname Maguchi means "while" (間) (ma) and "mouth, entrance" (口) (kuchi/guchi).


  • Reiko looks to be in her early 20s at the time of her death.
  • Reiko was the main reason why Tsurara Takahashi killed herself, due to her exposing the pornographic photographs of the girl.
    • Reiko seems to have been jealous of Tsurara.
    • Hyoka Nagatsuki who inquired of the grade leader and knew the circumstances of the incident was suspected that Isoko Anjou was the culprit who leaked the photo until Reiko knew it was the real culprit.
  • Reiko confirmed that she has frozen Kuraki's sperm just to have the man's child.
  • Reiko stick's ability is very similar to Kyu's ability.
