Normies reincarnating into a villain or villainess, NEETs reincarnating into monsters, Normies and NEETs reincarnating into the undead, hero or inanimate object, etc etc... we've seen them all.

Follow Airi (or her clones), a goddess of Karma, in her adventures of pushing up the hero/heroine with her blood (literally), sweat (literally?), and tears (literally)!
