Kiwako has faith that her grandchildren can handle the cult situation not because they come from a line of powerful mages; but because they've demonstrated their strength through training. Being concerned about their health, she arranges for a well-known doctor to help them in their task.

The Kusanagi head is shown to be strict and stern to both her grandchildren and strangers alike, terrifying the latter.

Appearance
"Those turquoise eyes that have lived through war, were reborn and now see generations’ worth of peace. She looks at no one except for us four. Doll-like in the way she holds herself and I can pinpoint her genes passed onto us."

Backstory
Kiwako met Daniel Vincent when they were both in their younger years.

During her youth, the Kusanagi and Hoshizora were rival families; to the point they started a war with one another.
