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, the legal age to receive their inheritance from their Grandfather.
Despite his "evil" appearance, Kogarashi is very loyal to his assigned Master and will take any measures necessary to complete his given tasks, using a wide variety of special powers at his disposal along with a practically indestructible body. However, he tends to act on his own intentions when he feels like it, and his approach only tends to make matters worse most of the time.
Yet Kogarashi is also proven to be highly intelligent and a mathematical genius. His social skills seem to falter 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 was also spotted in Goshuushou-sama Ninomiya-kun anime episode 3 as one of the hired persecutors by Reika Houjou to deepen Mayu Tsukimura's androphobia while she was walking in town.
