Luck Franzen

This S-rank adventurer disappeared after a dungeon raid, only to reappear a decade later having conquered all the monsters within. Upon his return, he finds himself hailed as a hero with a statue in the capital, prompting him to reconnect with old friends and restart as an F-rank adventurer named Lock. He teams up with Ario, a fireball caster, and Genie, an archer, while also encountering the B-rank adventurer Sia on his new journey.
