Rie Sekiguchi's Links
Although neither of them talk very much, Ichika seems to have a grudge of some kind toward Rie.
Rie is also a 1st year who is mature for her age, though Suzu tries to get her to loosen up and be a bit more kind to those around her.
Another first year who, although also quiet, intimidates Mimi and acts superior to groups like Tropical Vapor.
