The previous student council president before Amakusa Shino, who is now a university student. She's characterized as a person who is overwhelmed with modern technology to the point that she uses a abacus over a calculator. She is also presents an unfazed demeanor by Shino, Aria, and Yokoshima-sensei's usual antics. Overall, her interests is seen as somewhat old fashioned with her preference for traditional snacks and her use of 80s slang (to the confusion of others). This and also her behavior of giving out alot of souvenir when the group came to visit, brought to mind to both Suzu and Tsuda of the antics of an aunt.
