At Least Reincarnate Me as an Adult!

In the Duobu Continent, this is a continent of magic, warriors and dragons. There are many strange creatures scattered throughout the countless mazes. Inside the mazes are endless treasures, secrets, and magic books. A graduate of a technical school, an outstanding factory boy, who worked too late at night or died suddenly in front of the bathroom mirror due to his handsomeness, reincarnated here and was chosen to become a demon-slaying warrior.
