There Is a Succubus in My Room: A Succubus Reverse Isekai Harem LitRPG (Earthbound Succubus Harem #1)

Two succubi fell through dimensions into my apartment. Neither of us knows why. But if I don’t help them survive, we’re all dead.

I was having a normal Tuesday until I found a beautiful woman collapsed on my floor.

She had small horns. And a tail. And absolutely no idea how she got here.

Lyra is a succubus—banished from her demon realm through a portal she didn’t open, pulled by a beacon she can’t explain. That beacon? Apparently me. I don’t know why. Neither does she.

But here’s what I do she’s starving. Succubi feed on sexual energy, and without it, she’ll die. So when she nervously explains what she needs to survive… I help her. What kind of guy would let a stranded demon starve?

Things get complicated when a second succubus crashes onto my balcony.

Cherry is pink-haired, impossibly stacked, and radiates an aura that makes my neighbors confess their deepest secrets. She doesn’t understand why humans wear clothes. Or use money. Or get embarrassed about anything.

Now I’ve got two gorgeous demon women trying to figure out refrigerators and TV remotes while something monstrous hunts them across dimensions. The Inter-Realm Wardens don’t care that they came here involuntarily—they just want to drag them back to prison.

And the glowing seals that appear on the succubi during… intimate moments? I’ve seen those patterns before.

In my dreams. Before any of this started.

What the hell is happening to me?
