During a dungeon conquest, Rick, a support mage, is abandoned by his hero party. On the brink of death, he finds himself in a mysterious space where a goddess bestows upon him the almighty "Genesis Magic." Although he narrowly escapes his peril and even rejoins the party once, Rick quickly grows weary of his companions who continue to mistreat him. So, he hatches a plan—to get himself deliberately expelled.

With his newfound freedom, Rick intends to fully enjoy life in another world. But instead of peace, his "second life" brings one upheaval after another— encounters with a troubled young girl, confrontations with old grudges, battles against corrupt merchants... It seems trouble will follow him no matter where he goes!?
