Maou-sama, Retry!

Oono Akira, an everyday working adult, is transported to a different world while logged into a character known as the "Demon Lord" in a game he manages. There, he meets a girl with a disabled leg and they begin to travel together, but there is no way that others will leave a "demon lord" with such overwhelming strength alone. While being targeted by countries and saints that are trying to subdue the demon lord, they cause turmoil wherever they go. Demon lord on the outside, normal person on the inside, a misunderstanding-based fantasy!
