Grandma in the Magical Girl

[MysteryShadow]

After being nice to a fairy creature a Granny is granted the gift of being able to turn into a young magical girl. She seems happy about it until she discovers she now has to fight demons running amok. I originally noticed it on ExHentai than traced it to this facebook of a Chinese author. https://www.facebook.com/pg/animesto...89984955012948

I've seen a few other manga like this one
