Description
Hisui Tsurumi is a high school student with chin-length blue hair, yellow eyes, and constantly wears glasses. Splashing her with water within an hour of consuming cucumbers triggers a partial kappa transformation, revealing a shell and a kappa plate on her head—a trait stemming from her identity as a kappa, a reptilian water spirit from Japanese folklore.
Extremely shy and nervous, especially around those outside her small circle, she feels pronounced discomfort around males due to minimal exposure throughout her life. This anxiety often causes her to seek refuge behind her close friend Lilishka. She enjoys reading books, finding common ground with others like Shintaro Tokumitsu through literature discussions.
She comes from significant wealth as the granddaughter of the chairman of the Tsurumi Group and president of the National Kappa Alliance, with family ownership of multiple villas and helicopters. Designated heir to become the supreme kappa, her upbringing was highly sheltered. To preserve her chastity for this role, she attended all-girls schools and was surrounded exclusively by female staff, leading to almost no male interaction before high school. A pivotal event occurred in middle school when she rescued a fortune teller from a canal. This fortune teller advised Hisui to "seek an environment with a male presence," a directive she took seriously due to the cultural significance kappas place on water-related omens. Motivated by this, she deliberately enrolled in a co-educational high school despite anticipating difficulties.
Within the co-ed school, she joins the Occult Club. Her initial interactions, particularly with Shintaro Tokumitsu, are marked by intense nervousness, which he initially misinterpreted. Through shared interests like literature and gradual exposure, they develop mutual understanding and friendship. Overcoming her anxiety to connect with him and other new friends signifies significant personal growth. She explicitly states that enrolling in the co-ed school was worthwhile because it allowed her to meet these individuals. Key relationships include her reliance on best friend Lilishka, a fellow Occult Club member who helps navigate her shyness. Her family employs twin maids, Aoi and Kujaku, and her grandfather is central as leader of the kappa community.
Her character development is showcased through group activities, such as participating in a festival celebration with the Occult Club after exams, indicating her increasing social integration.
