One of Yuichi's friends who participated in the Tomodachi Game with her friends. She is portrayed as a shy and timid girl and often becomes victim of minor bullying.
In game 2 it was revealed that she engaged in Enjo Kosai (compensated dating) during junior high because she was in dire need of money. In junior high she was a victim of serious bullying and realized that she could protect herself from it by simply offering the bullies some money. That's why she got involved in compensated dating with an adult man but she claims that she never slept with him and that she ran away when she got scared.
Shiho was the only one who knew about this. That's why she blamed Shiho for spilling her secret during the second game.
