The Days When the Brave Is Not Around

The Demon's Birthday Calendar is a calendar that uses the day when the Demon King was born as the first day of the first year of the Demon's Birthday Calendar. In the 3976th year of the Demon's Birthday Calendar, the Demon King was defeated by the brave, and that day was the first day of the Peace Calendar. However, just a few years after the good days, the devil came back. He relied on the magic of reincarnation to be reincarnated into the heir of the brave man. It was the thirty-eighth year of the Peaceful Calendar. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
