You play as the infamous and apathetic Undead King, one of the “bosses” in an already dead MMORPG where NPCs are now the people living their so called “normal life”.
Everything starts when the Demon King visits you after X years of your capture for the first time, asking a huge favor in exchange for your freedom: inherit and become one of the seven sins, Lust.
After accepting the said Sin, you also unexpectedly gain back the humanity that was lost long ago ever since you turned Undead.
Now is the time for your redemption. Transform your daily life, from a former passionless zombie, into the ultimate Casanova, since the effects of Lust not only applies to you but everyone by your surroundings.
