Road of the Wedding: Yuusha no Konkatsu The Road of the Wedding: Marriage Hunting of the Heroes

Synopsis

Damien and his friends have defeated the Demon King and become the heroes of time. In a world where peace has come, all that's left is to marry the princess and live a slow and comfortable life...yeah right! Things aren't as easy as that "fantasy!" After saving the world, 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! (Source: GOT, translated)
