The World's Strongest Rearguard - S01

After dying in a bus accident, overworked salaryman Arihito Atobe wakes up in Labyrinth Country, where newcomers become Seekers by picking their own job classes. He hopes for a quiet second life, but instead ends up stuck with an unprecedented Rearguard class whose true identity even the Seekers Guild cannot figure out. As Atobe puts together a party and heads into the country's labyrinths, he slowly learns that his mysterious abilities have extraordinary support potential. But with neither allies nor enemies able to grasp the full nature of his class, mastering its hidden power may turn out to be his biggest challenge.
