The Mediator
Voiced by: Mai Nakahara

A sensible mediator between humankind and the fairies. She is one of the few humans left capable of creating sweets, which causes the fairies to naturally flock to her. Having observed the slow decline of humanity, her outlook on life is grim.

  • Bad Liar: She's not that good at making excuses for the fairies' mischief. Y explicitly calls her out on this during their school days.
  • Chronic Hero Syndrome: Despite being overly pragmatic (and somewhat lazy), the Mediator will usually go out her way to help others. This was most prominently featured in episode 6, in which she sabotages the electric generator in order to prevent P-ko and O-taro from leaving the solar system.
  • Defrosting the Ice Queen: Starts off as an aloof and distant individual during the beginning of her first year in school. She loosens up after making friends.
  • Advertisement:
  • Everyone Calls Him "Barkeep": Everyone refers to her as the Mediator.
  • Fire-Forged Friends: Grows into this with Y, after the latter coughs up some interesting information on the individual members of the Wildrose Society...
  • First-Person Smartass: She has her moments.
  • First Person Snarker
  • I Just Want to Have Friends: Episode 11 focuses almost entirely on this.
  • Jerk with a Heart of Gold: Beneath all that pessimism and apathy is a genuinely nice person.
  • No Name Given: The ending credits list her as "Watashi".
  • Prehensile Hair: A side effect of the Fairy Co. hair grow Lotion
  • Rapunzel Hair: Her hair starts out as short in the first episode, but then she uses a Fairy Co. hair tonic that makes it grow down to her hips.
  • Sugar-and-Ice Personality: Aloof and standoffish (more so when she was younger) but a sweetheart when you get right down to it.
  • Advertisement:
  • Sweet Tooth: Possibly, seeing as how she bakes sweets as a hobby.
  • The Smart Girl
  • The Stoic: Very much so.
  • "The Reason You Suck" Speech: Delivers a particular nasty one to Y when they were in school.
  • Tsundere: During her school days.
  • You Gotta Have Blue Hair: Pink hair, in her case.
