The Oono Mother is the mother of the Oono family that was murdered by Numazawa.
Not much is known about her personality but she was willing to try to escape with her family from Numazawa's control.
She was an adult woman with long light-colored hair that extended past her shoulders, and wore a light-colored jacket with dark-colored sleeves. Nothing else is known about her attire since the rest of her body was melted away by Numazawa.
Not much is known about her past, but at one point she married a man and had two children. During the beginning of the Era of Chaos she, along with her family, headed to Yamatoyama City to try to escape the goblins' attacks. On their way there, they were captured by Numazawa and his group. Days later they tried to escape, but were found and killed by Numazawa.
Her body, along with her family's bodies, where found by Teppei. Teppei then burned their remains. The next day Teppei learned about him, and his family's, attempt to escape, and that Numazawa was the one who had killed them.
