Kaga, Kouko

加賀香子

She had a perfect future planned with Mitsuo Yanagisawa as her intended husband, and nothing would stand in her way. She is Mitsuo's childhood friend, having been classmates with him from elementary school through high school. She is so infatuated with him that she often finds ways to isolate him from others and even displays hostility toward any girl who approaches him.
She possesses a non-violent side, as Mitsuo has described, characterized by her loyalty and devotion to those who show her kindness.
She comes from a wealthy family involved in the healthcare business, owning various private hospitals across the country.
