After a long journey, Noa finds the "Class Change Book." He's done to all to abandon his bothersome "Hero" role and gain a new class... "Monster Tamer." (Source: MANGA UP!)

I, the Duke’s daughter Carol Ambrose, one day suddenly had my engagement broken by my fiancé his Highness Reyford. I completely don’t have any recollection of harassing or trying to push anyone off the stairs though. But since it’s a good opportunity, I think I’ll propose to the Knight Captain I’ve yearned for ever since I was young. Because towards the white bearded and 62 years old knight captain Wilhelm-sama, there isn’t a single frivolous rumor and he’s still a bachelor.
