The youngest of the three sisters serving the Order of the Sun as a Hitsuka.
She is trying her best to become a good Hitsuka, and puts effort into helping her sisters. It seems she is also trying to do her best talking with others, but that doesn't seem to be faring very well.

Through her interactions with friends, she begins to think about who she really is. Sometimes, she tries too hard, which leads her to fawn over Otsuu and Little Mermaid.
