Demon Lord, Retry!

Akira Ono, a man trapped in the body of his own MMO’s Demon Lord, is just trying to find a way home while building a relaxing hot spring resort. His plans are interrupted when a dangerous Satanist cult launches an attack on the capital of Holylight. To handle the threat without drawing too much attention, Akira adopts his alternate persona, the dragon-riding hero Zero Kirisame.
