Otoboku: Takako Itsukushima 1/8 Scale Figure

The main character, Mizuho, is a nice guy who is part of a good family, is smart, and moral. But one day, he has to transfer to an all-girls high school thanks to his grandfather's dying wish. Unfortunately, he has to disguise himself as a girl to go to the school... Takako is a Tsundere character, meaning she is cold to the main character at first, but becomes lovestruck later on.
