Obara Karin♀

Third-year student and self-claimed volunteer of the ministry. She worries about the protagonist's hospitalization and often visits him. When the protagonist and Nanoka were seeking the ministry's help in reviving the gardening club, she did everything she could to help. Cheerful and energetic, but also mischievous, she actively helps with the atmosphere in her circles. She doesn't care about who is the senpai or kouhai with her close friends. Because of her parents' work, they are rarely ever home, so she is basically living alone.
