she already familiar with the magical creatures, her reaction is because someone try to kidnap Akane, like a strange person just broke in her house and kidnap her kid.I'm just going to assume Mom didn't panic or anything about magical creatures clearly absconding with Akane because the cats didn't seem bothered, so the little magical creatures PROBABLY explained to the cats.
a bunch of chapters back Akane stopped time in basically all of Tokyo.Get to see more Wilder side of the Witchy stuff. Nice!
