Yuusha Party wo Tsuihou Sareta Shiro Madoushi, S Rank Boukensha ni Hirowareru: Kono Shiro Madoushi ga Kikakugaisugiru

Summary

"We don’t need a useless white mage.” Lloyd is a white mage who was unexpectedly banished from the hero’s party. As he was lost and uncertain, he happened to cross paths with an S-rank adventurer party in need of a white mage, so he joined them on their quest. Little did anyone know at the time that the hero’s party would fall apart and Lloyd would rise to fame. This is a story about an unmatched support magic user, who believes himself to be ordinary, becoming an unstoppable adventurer. (Source: Crunchyroll)
