Multi World Harem?

I wake up, startled by what just happened. That's right. Truck-kun. 'Was that a dream? It felt WAY too real for that. And where am I? Heaven? This would be a pretty boring heaven.'

Inside the room is 4 doors, one on each wall. They are plain oak doors, with copper handles and no windows. The room is lit by a clear over head light in a circle shape, with no light switch. 'Is this a maze?' "Hello?" No answer.

Looking down at myself, I see I have no clothes on. Another thing I noticed is that I look younger. I was about 30 when I died, but I look no older than 15. I stand up and look around the room, and mark one of the doors so I don't get lost or turned around. I take my finger nail and scratch a large N, for North on one of the doors. I don't see anything else in the room. As ready as I can be, I enter the north door, seeing a black forest on the other side.

"Huh?" I walk out and look back, but the door is gone. "HUUH?!" I look around and find a large stick, placing it where the door used to be. As I look around I hear a sound in my head, like a massive gong went off.

(First world:??-First world quest:-skills: Return,luck, unnatural body, adaptive, adaptive resistance,anti-insanity-)

As the gong goes off, a screen appeares in front of me. "First world? Do the doors lead to different worlds?!" I yell out in confusion. Seeing the return skill, I try to click it to see if I can use it, but my hand goes through the screen. Instead I try to focus on the word, like the systems in novels. I try to think back at one of them that I have read before but come up blank. In fact, I can't remember... anything. I start to panic, almost hyperventilating, before calming my mind.

' Ok there has to be a reason I can't remember anything.' Looking at my skills, I see a few that are odd. Unnatural body, anti-insanity, and adaptive/resistance. Unnatural body probably makes me stronger? Anti-insanity is just weird, but that might be the reason I'm not going crazy with all my memories gone. Adaptive and adaptive resistance I know are usually powerful, so with all of these weird skills, maybe- I hear the sound of footsteps nearby, and quickly try to use the return skill.

I suddenly jolt awake, finding myself in the room again. The hell? I look around and see the door marked N, proving that this is the same room. As I think about it, the screen appeares again, and I notice a cool down by the return skill for 24 hours. I concentrate on the other skills and pull up information about them.

(Luck- improved natural luck/unnatural body-you become much stronger much faster/adaptive-you mentally and physically get better the more you experience/adaptive resistance-gradualy become more resistant by exposure/anti-insanity-always retain your mind, never losing yourself)
