Hariu Rinko

A third-year student with a cool aura, and a serious scholar who is always at the top of her class. Her cold appearance makes her seem unapproachable, so she is awkward when interacting with other, so she avoids getting involved with the people around her.
Contrary to her feeling, she can't avoid taking care of others due to her methodical nature, people tend to ask her for help since she can't say no.
She has no experience with love, so is confused when the topic of romance and sex comes up
