This dear has a tragic life story! I adore the nods to real world lore of dragons, having him hoard and collect things, and dabble in some interests. I love this trope every time I see it. Additionally, the fact he must hide his wings through such a painful process and not a simple spell is a nice touch. It adds depth and realism to the character, especially with the crippling effects a lifetime of this practice would bring. I hope Jiro learns to fly someday! And Jiro's love for literature and manuscript collection is something I adore. Characters who read are always nice to see.
