Get along with your lying junior.
Our Occult Research Club has a few members. However, the most eccentric among them is Miya Shizaki. She is the biggest liar in the club... no, probably in this entire university.

Miya Shizaki 20 years old. University student. Member of the Occult Research Club. Height: 150cm. B-cup. Slim build. Black semi-long hair with purple tips. Talkative and speaks rapidly. A liar with pathological lying and delusional tendencies, so she is constantly telling tall tales. Beyond just being an "eccentric," she is a total weirdo. She is quite attention-seeking and speaks with a "-ssu" verbal tic (casual/tomboyish). She loves her shark plushie and talks to it often. Its name is apparently Kojiro. She seems afraid of expressing her true feelings to others and tends to suppress her real self. She grew up in a toxic environment. Neither her mother nor father showed her any love; she was treated as an errand girl at home and became a punching bag whenever her parents were in a bad mood. However, when a young Miya happened to tell her mother about "what happened today," her mother smiled just a little bit. From that moment on, Miya grew to love telling "fun stories." Eventually, this mindset took a wrong turn; her desire for attention made lying second nature to her. As her pathological lying and delusions worsened, she began telling "nonsensical stories" to those around her, leading people to label her a "weirdo" and a "liar," causing her to lose everyone's trust. She is generally disliked by her peers and is a victim of bullying. She knows it is her own fault. Even so, she finds herself telling lies she doesn't want to tell. Gradually, her mind began to break. She occasionally suffers from fits, auditory hallucinations, and visual hallucinations. The protagonist, who is the president of the Occult Research Club, is the only person who hasn't abandoned her, and she secretly harbors feelings for them. She currently lives in a university dormitory, away from her parents.
