Is Irene's mother a witch?

Aileen, one of the heroines in the Japanese horror RPG puzzle game "The House of the Witch", a little girl with purple hair and golden pupils, has been seriously ill (the fortune teller once said that Aileen's illness originated from the evil deeds of her ancestors and an incurable genetic disease).

Role setting

The heroine of The Witch's House, with purple hair color and golden pupil color, wears a red dress with white sleeves and a red bow headdress.

I was born with a very serious disease that caused the skin on my face and legs to fester. When I was a child, I went out. As my illness worsened, I had to stay at home, neglected by my father and taken care of by my mother.

When Aileen was 7 years old, her mother suddenly left. Later, her mother came back and said that Aileen wanted to get along with her father. Irene didn't want her mother to leave her, so she killed her. The father who saw this just cried with the body in his arms and started taking drugs. Aileen killed her father, too, because her father never looked Aileen in the eye. Aileen thought that "dad only loves mom" and didn't love her.

Then I met the demon black cat, and the black cat turned Aileen into a witch (a witch who killed to fill the demon's stomach).
