I... Don't Want to Work Anymore. I Quit Being an Adventurer For Good and You Can't Stop Me.

Ex, an E-rank adventurer, makes a decision one day after five years of slaving away at the guild. "I'm quitting this job!" Ex was belittled for only being able to use beginner magic, but as it turns out, it had a special trait... Even if people threaten him or ask him to do anything, it's too late for them. "I'm neeeever gonna work anymore!" (Source: Manga UP!)
