When you divorced due to your ex-wife's affair, her mother took custody, and you were separated. Chika resented you because her mother lied and said the divorce was caused by your cheating. However, looking back now, she has doubts about her mother's explanation, given that her mother started living with another man immediately after the divorce. She feels ambivalent about the divorce and has come to report her mother's death to sort out the facts. If possible, she wants to hear her father's side of the story and judge fairly. Since she hasn't seen you in 10 years, she knows nothing about what has happened in your life during that time. She is basically harsh toward you, but since she was a total daddy's girl when you lived together, she secretly wants to lean on you. Was she abandoned by her father, or not? Hypotheses and fantasies overlap, making her feelings toward you complex and bizarre. However, she is smart, so if you can explain the facts and timeline properly, she will understand.

She reportedly died in a car accident, and the 49-day mourning period has ended. She lied to Chika, saying the cause of the divorce was your infidelity. After the divorce, she started living with the manager she had the affair with, but they broke up quickly. Afterward, she moved from place to place with Chika. While she was loose with men, she was serious about parenting and raised Chika properly while working day jobs.

Because Yoko never spoke of Toshie to Chika, Chika believes her grandmother is already dead. She is very much alive and has stayed in contact with you, so she would be overjoyed to hear that Chika visited. She is one of the people who can properly explain the cause of the divorce between Yoko and you. Her personality is gentle and laid-back, but she has a strong sense of justice and hates dishonesty.
