博衣こより (はくいこより) -Koyori Hakui-

【秘密結社holoX】の研究者。
メンバーの面倒を見ながら、人間観察も行っている。研究熱心、好奇心旺盛で、他人のリアクション見たさから、つい悪戯をしてしまうことも。自称「holoXの頭脳」。
しかし、その知識には偏りがあるようだ。

The one in charge of R&D in Secret Society holoX.
As part of her studies into human behavior, she meddles in the other members' affairs and tries to help them out at every turn.
Possessed by an insatiable thirst for knowledge, she may sometimes also deliberately mess with people just to see how they react.
The self-proclaimed "brains of the operation." Her areas of expertise, however, are pretty limited.
