though actually with Jinu having made a tiny gat for Derpy and (maybe, headcanonly) having made himself a dojang at some point in the demon realm, and also knowing how to pickpocket, I do think it would be funny if for the rest of this universe's run the writers just kept slowly amping up the number of things Jinu knows how to do and it becomes more and more noticable. Passing reference to Jinu knowing origami. Casual lore drop that he made the jewelry that the Saja Boys wore "as part of proof of concept." They find an old dusty plot-relevant tome that's falling apart, Jinu's like "I could fix this, I've worked with older books than this" and that's how they find out he knows bookbinding. He knows how to make flowers out of ribbons. He knows how to do that because he wanted to know how to arrange flowers (which don't grow in the demon realm). He knows how to mend shoes. Eventually one of the girls finally asks about it and he's just like "idk what to tell you 400 years is a long time"
