Ninjadork and Kaarme are on point.
It was refreshing to see the "impossible" solving of the quest achieved by Desir. I suppose he lied to his teammates to keep them focused. Desir's goals are refreshingly uncommon in Isekai. He doesn't desire to dominate--he wins definitively but closely--but to spur his talented friends to grow. They grow, but he still wins in the contests. This series is fun to read.
