Kirigaya Midori

Kirigaya Midori (桐ヶ谷翠) is the mother of Suguha and aunt/adoptive mother of Kazuto. She is an extremely busy woman and leaves the two kids to care for themselves, only coming back to the house late in the night and leaving early in the morning.

Background
She adopted Kazuto in 2008, after her sister's death and kept it in secret until Kazuto discovered the erased documents in the National registry in 2018. She herself also played virtual games like Kazuto yet never reached the level of seriousness that Kazuto had.

She told Suguha the truth while Kazuto was trapped in Sword Art Online at the hospital.
