Really enjoying this so far. It took five chapters, but with the Stone of Dullahan absorbed, we've finally gotten the final puzzle piece described in the description. Now it feels like the real story can begin.
I'm a little wary about the last bit in the description about "being chased by an assertive fiancee and Female Knights." It's obvious who the fiancee is—even though he was five and the engagement gift was kind of accidental—but I hope that the story doesn't devolve into a full-on harem. (I don't automatically hate harem stories, but this one feels really wholesome so far that turning it into a harem would detract from that. Also, I think it would be nice to have a star-crossed romance between Ain and Claune that occurs between adventures, separated by their two kingdoms but destined to end up together.)
