New world
A soul abruptly started moving around in black void. He just floated and floated, eventually becoming in raged and frustrated by his predicament. His soul started becoming darker and gained black spots that contrasted with the white.
Then a ominous purple and black portal started swirling around and a extremely handsome man stepped through.
He was wearing an all black suit with dress shoes to match. He had sharp features and he had black flowing hair that went down to his mid-back.
"You poor soul. Do you want to leave this place?" The mans powerful voice shook the void.
Even though the soul couldn't do anything it's intentions were clear. It wanted out of that place by any means necessary.
"Then will you follow me, Satan , as a my champion?" He said.
The soul was suspicious when he herd who he was talking to, but since god isn't here he'll go with satan and get as strong as possible.
"Being my champion will enable you to tons of perks.
1. You will be extremely handsome.
2. You will have unlimited growth potential
3. You will be able to see through all lies
4. You'll have my own demonic arts
5. you will receive the power to jump worlds
6. You will get a demonic constitution or body."
The soul was impressed. All of this sounds OP as hell. He was curious about the demonic arts though.
"Since you agree go ahead and picture you ideal body and starting world. Your goal is to get as strong as possible and await my call." Satan said.
The soul pictured his ideal body and was ready for reincarnation.
"Your starting world will be Danmachi. Good choice your body can take in the demonic air that's in the dungeon, just a beginner tip."
After he said that the soul disappeared.

<In a forest>
In a forest was a kid who looked to be twelve. He was laid out on the ground in clothes that looked new. He had hair that started off black on the left, but had strands of a blonde brown on the left.
His hair was long and framed his face while his bangs hung between his eyes. He suddenly opened his eyes. The boys eyes were sharp and mesmerizing.
On his left eye was pink while his right eye was a turquoise blue.

He slowly got up and looked around. He then clutched his ears and basically shriveled up into a ball.
.....
<First POV>
I looked around and noticed I was in a forest. The air was fresh and the forest was filled with healthy greenery everywhere. Then out of seemingly nowhere my body felt stronger and I could hear everything.
"AAHHHHHHHHHHHHH." I yelled and curled up in a ball covering my ears. All the sounds of everything went straight to my ears and they felt like they would burst.
I tried to control myself and was trying to get my hearing to get lower. After a few minutes of trying I was able to hear regularly.
My vision was still really good though and I could zoom in and out like binoculars. My body felt like it was bursting with energy and power. I took off the black jacket I was wearing and saw my body.
My arms muscles were visible, but not chiseled out. I flexed and my muscles bulged out and feeling them, they felt like a brick.
I pulled my shirt up and saw a six pack. I felt them and they were just as hard as my biceps. I walked over to a tree and punched it with as much power as I could.
The tree flew from its roots and smashed into another tree toppling it. I looked at my hands and clenched them. I could feel the power.
I raised my right leg up like pitchers do in baseball. I then slammed it down in front of me and I made a small crater.
'So I can be sure this demonic constitution gives me superhuman physical capabilities. I'm also extremely flexible. How do I use the demonic arts then?' I thought to myself.
[Champions helper system online]
'A system?!?'
[Yes host. Satan wants his champion to get strong as fast as possible, so I will assist you.]
'Oh. Can you go over your functions?' I asked in my head.
[I have a [Shop] that uses any type of money to buy things. In the shop are techniques used by the demon kin. I have [Battle Room] function. It's a simulation of monsters that are from the demonic realm that you can fight for rewards. My last function is [Status] to see your strength. Lastly I have [Inventory] to hold your rewards and items.]
'Okay, I'll call you Eve.'
[Thank you for naming me master. You have the kata for the [Demonic Arts]. The Demonic arts range from Novice to supreme.] Instead of metallic the voice changed to a mature and serious accountant or secretary woman's voice.
'Thank you for the note Eve.' I then thought about my inventory and a black hole appeared. I stuck my hand in and pulled out the [Demonic Arts] manual.
Then in a burst of black flames the book went in my head and I gained the knowledge of how to perform the [Demonic Arts].
'Eve right now, what period of cannon am I in?' I asked taking a stance in front of a tree. I lowered my strength to normal.
[Cannon begin in two years. I'll set a timer for when cannon starts.]
'Thanks again.' I said and threw a sloppy straight punch to the tree.
[You have an unopened gift in your inventory.]
'Open it.' I said throwing a barrage of flimsy and sloppy punches.
[Its a gift from Satan. He gave you the [Purging Flame] ability. You concentrate your demonic energy into your hand and shoot out a burst of red flames that destroys anything.]
'Okay. Can you show me my status?'

"Is the demonic grade my overall strength?" I asked.
[Yes. Currently your weak, but that will change soon enough.]
"Okay."
I spent the rest of the day training in the [Demonic Arts] it's a fighting style for high ranking demons, but it's incomplete without [Demonic Energy].

<Next day>
"Eve. Why don't I get hungry, thirsty, or even sleep?" I asked. Right now I'm sitting in a lotus position getting ready to feel my own [Demonic energy]. I didn't sleep last night, because I never felt tired.
[You have a demons constitution, so you don't need water, food, or sleep. You can still do all of it though.]
"That's good, because I have no experience in hunting and I can't see anything besides trees." I laughed lazily.
[Now let's get back on track. First clear your mind and stay calm, lower your breathing and once you feel-]
"I can feel a burning energy in my stomach right now." I said sweating.
[Oh, well you need to contain it. Make it-]
"I just condensed it into a ball." I said breathing a sigh of relief.
[Well, master did say you would be talented.]
"Now I just need to make it slowly flow around my body right?"
[Are you sure you need me?]
"YES! In my past life I just watched a lot of anime, so I sort of know this part." I said.
[Okay. Then yes make it flow over your body, but don't let it out of control. You could die.]
"Thanks Eve"
[No problem Kyo. That is why I'm here.]
Said Eve with pride evident in her voice.
I then started guiding the energy go around my body. My body felt tingly and then warm, I started feeling stronger, but more relaxed.
[Kyo, you have unlocked your Demonic energy and received the following: [Energy Manipulation] [Full Focus] [Energy Reinforcement]. You are now a Novice energy user.]
