I actually really love that, did wonder how they were going to catch him out.
Side note I'd love to see a spin off or other series focusing on being a crafter for hunters. I know there's one with a toddler rn but they don't really focus on*how* she makes, sources or creates her stuff. (There was a similar manga but for accessories &armour for adventurers and I'm sad every day that it doesn't have anyone translating it these days.)
