While the first two volumes of popular light novel series Ryuuou no Oshigoto! (The Ryuo’s Work is Never Done!) was mostly an introduction to Yaichi’s two disciples, the third volume went on to establish the development for one of the characters that is mainly overlooked before. Being a volume that heavily brings up the theme of talent and hard work, it still remains one of my favorite parts of the series.
Anyway, you can join the Discord server here to talk about the series. And as usual, spoiler warning.
