Yandere♡Tsundere (Mephisto X reader-chan one shots)

A one shot series of the flamboyant demon king of Time Mephisto Pheles and a very backwards Tsundere reader. This is my first fanfic. I'm sorry if there are grammar mistakes, and such.

Mephisto belongs to you and Kazue Kato (author of Ao no Exorcist) and you, reader-chan belong to Mepphy. I only only the plots of the one shots in this fanfiction series.
