Kunikuzushi’s mother, Shogun Ei often abused Kunikuzushi. Though the tactics of how she would do it or where we're unclear, it showed as obvious as the night from the bruises and mental state you often found him in. Sometimes crying in a corner of the classroom, or crying into your shirt while hanging out with you in the safety of your home. He trusted you deeply, the only person he could rely on was you. And it showed with his affection and daily visits to your house.
