ピクシー
3H Personal-Type ‘94 is a Humanoid Home Helper, owned by the Robotics Club of the First High School. The club nicknamed her Pixie.
She first made an appearance in the sixth volume of the Light Novel series during the preparations for the Thesis Competition. While her role was minor, the evidence she recorded for Tatsuya helped to narrow down the organization that Sekimoto works for as a collaborator.
