Kogarashi
メイドガイ・コガラシ
Kogarashi, The Masked Maid Guy, was hired as a Maid/Bodyguard to protect and serve Naeka and Kousuke Fujiwara until they turn 18 when they are at the legal age to receive their inheritance from their Grandfather.
Yet Kogarashi is also proven to be highly intelligent and a mathematical genius. His social skill seem to flaw under that as he does not understand the meaning of “privacy” in any way, this resulted in him being called a Pervert though he only sees his actions from a professional point of view in aiding his masters well being.
He also was spotted in Goshuushou-sama Ninomiya-kun anime episode 3 as one of the hired persecutors by Reika Houjou to make deeper androphobia to Mayu Tsukimura while she was walking in town.
