[Read up to chapter 5, you won't regret it.]Haru Mizuki died the lamest death possible: alone in his room, playing a hentai VRMMO. No heroic sacrifice. No tragic accident. Just... pathetic.But instead of oblivion, he wakes up in Aethelgard.Cursed by Chronia, Goddess of Time, Haru gains an ability no one else has: he can't stay dead. Every time he dies, he loops back to his last checkpoint. What seems like a curse becomes his greatest weapon, infinite retries mean infinite opportunities to learn, train, and seduce.And seduce he must. Because Haru's cheat ability, Touch of the Goddess, lets him steal powers from anyone he touches... but it works best through intimate contact.Armed with death loops, a hacker-class system that lets him sabotage rival players, Haru begins building the ultimate multi-species harem. But he's not the only player in this game, and they all want the same thing: absolute domination.
