The Banished Court Magician Aims to Become the Strongest

Overview

"This party does not need a useless magician who can only use support magic. You are fired, Alec Huguette." One day, Alec, a court magician who had been chaperoning the Crown Prince's dungeon-crawling party, was suddenly fired and banished from the court by the prince. The only one who reached out to him is Yoruha, his former party member from their Academy of Magic days, that had split up four years ago. "Hey Alec— would you like to come explore dungeons with us again?" Thus the legendary "Lasting Period" party was revived, and the name will soon became known all over the world once again.
