Haruna is Yui's classmate and best friend. An ace student, and a whiz at computers, but a bit of klutz. But she's always there for Yui.
Haruna has a fair skin, long pink hair and light blue eyes.
Haruna is a mild mannered girl who is believed to be a computer-knowledgeable genius. Originally, Haruna was a very shy girl and she considered herself as a loner. Once she is first approached by Yui at school, she slowly gets better.
