Whenever I read manga or novels about adventurers who are expelled from the legendary hero's party, I always think: Why do they disdain, humiliate, and expel someone who was useful in both theory and practice? (And sometimes it turns out the expelled person was stronger than the hero or group leader.) And I tell myself, they expelled them because "they had a shortcoming," as a mockery of that cliché and ridiculous premise. And I think, what if I write a story with that cliché premise? This is the result. I hope you enjoy it!

PS: This is my first novel; it's almost a writing exercise, but I really put a lot of love into it.
