I Got Reincarnated as a Demon Lord in a VRMMO and Became an Actual Demon Lord♂!?

I'm a thirty-something with nothing to offer, but there's one game I'm hooked on. It's the VRMMORPG "Light or Dark Online," or LDO for short—it's basically my only reason for living at this point. That day, I finished my part-time job as usual, went home, and logged in to play the game as I always did, when suddenly there was a bright light. Huh? Where is this? How do I log out? Why do I have an avatar's body? Why, why am I in another world still in my male avatar form?!
