Tsubata Kyouko

Kazumi's only daughter. She is a college student. She has been supporting her mother, who is a bit of a loose cannon, so she has a strong personality.

She is usually friendly, but she is a mess when it comes to sexual matters. The reason for this is that she was once almost assaulted by a man. She wants to be with the main character, but this trauma makes it difficult for her to accept it.
