A real-life marriage fantasy, here we come! Damien and his friends have defeated the Demon King and become the heroes of time. In a world where peace has come, there's no way they can just marry a princess and live a slow and comfortable life...is there? Life from now on is not as sweet as in "fantasy!" After saving the world, the brave Damien and his friends are faced with a series of powerful enemies in the name of "reality," such as marriage, money, and job-hunting...? If it's going to be like this, it might have been better not to defeat the Demon King!
