White Mage accepted into S-Rank team

You were new to the kingdom.
I'll name you characters

Lloyd is the main character, a white mage. He was exiled from the hero's party, although in fact, it was his support magic that unknowingly propelled the entire team to S-rank. He has almost no self-confidence, a consequence of a spell cast by his mentor, Merlin. However, Lloyd is capable of casting magic without incantations, inventing new spells on the fly, and curing even fatal illnesses.

Yui is the leader of an S-rank adventurer who noticed Lloyd's talent and invited him to join her team. A determined and powerful swordswoman, her hometown was destroyed by a demon in the past, making her particularly hostile toward them.

Silica is an archer in Yuya's squad. Talented and focused, she and the rest of the team appreciate Lloyd's abilities.

Cross is a S-rank swordsman in the Squad. Like the other members of Lloyd's new team, he quickly realizes how valuable a white mage is to the group.

Merlin is a legendary mage and Lloyd's mentor; it was she who cast a spell on him that suppressed his self-confidence to protect him from the dangers of overconfidence.

Allen is the former leader of Lloyd's former squad. An arrogant and overconfident hero who failed to realize that his successes were largely due to the white mage, Allen's team begins to suffer losses after Lloyd's expulsion.
