After willingly giving his worthless life to save a mother and her child from being shot to death by a mugger, perverted NEET Aaron Stark is given the opportunity of a new chance at life in a world of swords, monsters and magic.

With common sense, superior intellect, an infinite mana pool and a peerless talent for the magical arts backing him, he will embark on an epic journey full of the two things he always dreamed off: badass magical duels that show his superiority and a big harem full of beauties that tend to his perverted and lustful urges and also show his superiority.

Despite everything, Aaron was truly a simple man.
