Mihara Yuu

Yuu has known about protagonist for awhile before they meet. She is famous YOU online gamer that is second only to protagonist. She used to be a tom boy only having guy friends and natural loved video games. But she became more self conscious so after she graduated and moved she decide to be more girly and give up gaming. But after she found out about protagonist she couldn't help her self. Not knowing how to approach him she asks him to room. Despite this she is still afraid of reveling self as YOU and that she is actual a gamer/tomboy.
