His name literally translates to crazy. Well his last name.
He's the man who tortured and abused Lisa and her siblings.
So yea.
Lisa and her siblings and parents DO NOT get along with this man. Especially with Katherine.

His assistant/wife

Unlike her husband Tamashī is kind and sweet. She acts like a mother to her husbands "test subjects"
