Maou-sama, Retry!

Oono Akira, a working adult that can be found anywhere, was transported to a different world while logged into a character known as the “Demon Lord” in a game he manages. There he meets a child and they begin to travel together, but there’s no way that others will leave a “demon lord” with such overwhelming strength alone. Demon lord on the outside, normal person on the inside, a misunderstanding type fantasy!
