The weakest commoner who was banished rises to power and builds a harem! With his 'immortality' skill, he aims to become the strongest and get revenge on those who looked down on him!

In this world, people are born gifted with "Skills" and "Jobs." The protagonist, Heet, possesses the extraordinary skill "Undying," but his job is "Weakest Commoner"—a role that grants zero growth no matter how much he fights.

Because of his lackluster job, Heet is kicked out of his adventuring party. However, Nyune, the A-rank "busty" mage who arrives to replace him, has a major objection to the situation...?!
