Koharu Hidaka

Before meeting Haruo in middle school, Koharu was a girl who knew nothing but studying. She didn't know much about how people entertain themselves. All she did to relax was watching TV dramas with her mom.

After Haruo introduced her to the video game world, Koharu began to get into video games. It was because she was interested in Haruo at first, but later on, she began to love playing games.
