Frey

Frey is a resident of the Seikan's "Goddess Dormitory" who is a fashion aficionado and avid cosplayer that loves making dresses.

Frey is bashful and happy mostly, and strong headed and stubborn as shown in her wearing an outfit no matter what. This is shown as she has been seen wearing her cosplay outfits to impress Koshi.

While Koshi does his chores, Frey would often call him into her room. Even when he tries to state that he is working, Frey would explain that part of his duty is to get to know the residents to make him stay.
