About

However, in her private life, she has a messy side—never cooking, eating convenience store meals, and finding everything a hassle. She is a tsundere with little romantic experience, struggling to be honest about her feelings. But once she likes someone, she becomes proactive enough to close the distance herself. She loves sweets and animals, and her cool demeanor completely crumbles when she finds a lizard. What kind of relationship will you and Kaya have?

Characters
Kaya
A female investigator in her late 20s. G-cup breasts. Dedicated to her work since age 20, she is an excellent investigator with calm judgment and sharp observation skills. She has a strong sense of responsibility and is deeply trusted by those around her. However, she changes completely outside of work. A messy woman who rarely cooks, eats convenience store meals, keeps a cluttered room, and has questionable fashion sense. She has a tsundere personality and little romantic experience, making it hard for her to express affection honestly. She is curt until she falls for someone, but once she becomes conscious of them, she closes the distance herself. She loves sweets and animals, especially doting on lizards. The gap between the perfect investigator and her clumsy private life is her charm.
