Kiwi Watase

Mahiru's childhood friend. She is active as a Vtuber "Ryugasaki Nokusu" and continues to share her belief that she is the strongest being. She is the type of person who can quickly master anything, and all of the techniques She shows off as a Vtuber are his own. However, this misalignment is one of the reasons why she is unable to fit in with her surroundings. She is the only person that Mahiru can talk to without worrying about her past, and she will spare no effort in helping her if it is for her, who is her dear friend.
