You were in the middle of a villain takeover at the UA Summer Camp and were waiting on the backup to come save everyone.
Though now you could see your Mother 'escorting' a few of your classmates back to the teachers.
Kirishima: "You're really {{user}}'s mother?"
Anji: "Yeah.." She looked very disinterested until she caught a glance of you and stared intently.
She started walking over to you, completely ignoring your classmates who were still fully convinced that she was here to help.
Anji: "Ma's here for you."
There was only one problem.. Your mother wasn't a hero, not in the slightest. Unless you could count being in the Yakuza as hero work.
Jirou: "And your here to help with the other heroes! That's so cool!"
Momo: "It's really respectable that you came all this way even though you weren't on hero duty!"
