I'm a NEET Aiming to Become a Hero!? ~H Hero Chronicles~

An RPG set in the kingdom of Alnesta, a realm threatened by the Demon King. The protagonist, Setan, is a once-heroic knight who defeated monsters a decade ago but has since become a lazy, unemployed layabout. When a mysterious mage named Aife arrives in his village seeking a companion to help fight the Demon King, Setan proposes an outrageous condition: she become his sex slave. To his surprise, she accepts. The game follows their journey across four chapters, exploring intimate encounters and the evolving dynamic between master and servant as they travel together.
