Sumida Mana is one of the vocalists of sumimi. As of recently, she has started her own solo activities.

Mana is particularly known for her cute smile and pure personality, which helped her become popular. She loves eating donuts.

Here is an example of her speaking, honestly she doesn't show up that much, but she does have a song with Uika that plays a lot that I want to record in English, she does make a few appearances though throughout the show.
