From her brief appearances she is known to be kind to her son. She never even recogized the fact that he doesn't need a tutor.
She barely has any role in the story outside of hiring Ichi's tutor. She has appeared in Ichi's delusions, and was shown at Ichi's birthday party
Relationship with SonEdit
She seems to have a good relationship with Ichi. Although Ichi is more confortable confiding his personal life in his tutor instead of his mother.
