Kyou mo Kitansu ka, Yoda-senpai.

Synopsis

There is a girl who makes herself at home in our house. She is a friend of my sister and she is a senior in the same high school with us. It seems that it take her two hours to get to home from school, so she stays at our house almost every day instead. Yoda-san may act all playful and innocent, but her antics always get me all flustered! This is a love comedy under one roof between a cute devilish girl and an otaku boy!
