A protagonist whose reality turned into game; the power of save-and-load bestowed to him; heroines with different and unusual personality traits. This is a story that turns around the whole concept of a romance game.

The ability (power) he attained in the other world was "24 hours with no fatigue"!? "...it really is a bit overwhelming" Taking the blow for a female high school student who was attacked by a slasher, Kagi Tomonori was killed in an unforeseen accident and the curtains to his life came to a close...or it should have, but when he came too, before his eyes was a beautiful girl who called herself a goddess.

Tomonori, equipped with the ability "24 hours with no fatigue" applicable in terms of mind and body, followed the slasher into the other world and began his life as the 4th son in a viscount family.

As a human being his master was very peculiar. One might say that he was open-hearted but to put it frankly he was nothing more than a hedonist with a personality that couldn’t be any worse. He was constantly womanizing and when there was not enough money for lodging they would be forced to sleep outside and live off the land. As a result, the brother and sister went through a lot because of this powerless man.

*"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.
