"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.

"I don't need a worthless mage who can only use support magic. You're fired."
 
Alec, a court magician who supported the crown prince from behind the scenes, suddenly finds himself exiled from the royal court. Now jobless, he pays the magic academy a visit and runs into Yorha, one of his party members from his school days. Their renowned party once set a record in the royal dungeon—and now it's time to reunite and start a whole new legend!
