I think I read it about few weeks ago but I forget the title. The novel is about former member of hero party that going to kill demon Lord. The mc is the hero's brother. He thought that he is at the limit of his strength so he decided to leave party. Edit : it JP btw
I Was Kicked out of the Hero’s Party Because I Wasn’t a True Companion so I Decided to Have a Slow Life at the Frontier Someone read it and tell me if it's any good.
