Nakaimo ~My Little Sister Is Among Them—To inherit his late father’s corporation, Shougo must attend Miryuin Private Academy to find his future wife. As all the girls are friendly (especially two classmates, Konoe and timid Miyabi), Shougo must choose the right girl. Unfortunately an undercover agent discovers that one of the girls is his unknown younger half-sister, so Shougo can only hope he won’t chose the wrong girl. Due to some mature themes/content, no one under 18 will be allowed into the anime rooms after 10:00 PM unless accompanied by a parent or adult legal guardian
