Lyra leaned in, her eyes swirling like nebulae. "Stay," she whispered. "Why return to a world where you are a ghost in a machine, when here, you can be a god in a dream?" Mumasekai Lost In The World of Succubi
You play as , a 22-year-old cynical shut-in who falls asleep reading a forbidden occult manuscript. When he wakes up, he finds himself in Mumasekai — a decaying dimension ruled by succubi who have conquered all other demon races and reshaped reality into a realm of endless desire and despair.
