Riku Sasaki

Height: 160cm

A cheerful, emotional and sporty tomboy with a kind heart and keen interest in the paranormal, occult and unexplained. She strongly believes in urban legends and myths, dreaming of one day taking an authentic spirit photo and publishing a book proving the existence of the supernatural.

She's initially unaware of her true nature as a werewolf, losing consciousness on a full moon and forcing Reina to help her regain her senses. Afterwards, the two become friends, with Riku making sure to try and keep her werewolf self in check even without Reina's help.

She has a younger brother who's more rational and skeptical of the paranormal than she is, often making her upset with his logical approach.
