'Where did it all go wrong?' I thought, lying on the ground. Around me, the stone floor of the vast ravine was indented, with cracks creating a weblike formation on the ground. 'My right arm is broken, it's completely done for. My ribs are shattered, and my legs are bent in backward.'

"That motherfucker, Cedric. I'm fine with getting bullied since this was our last year, but this fucking piece of shit has the balls to push me into a ravine? I don't know whether to be fucking impressed or scared for the rest of the world, he's got balls of steel."

I coughed, and suddenly I spit out a mouthful of blood. 'Shit.' I used some mana and spread it throughout my body. A piece of the many broken ribs in my body was cut into my lungs, and my talking wasn't helping. I pushed myself up with my left arm and tried my best to look around.

"What the hell is this place?"

I was in the ravine that I was standing over before but on the other side of the waterfall that poured into it. I pushed myself away from the waterfall, farther into the hidden ravine, when suddenly the entire place lit up. "Human life detected, activating laboratory system. Welcome to Lab-548.", said a mechanical voice.

I shielded my eyes while adapting to the sudden brightness. When my eyes had gotten used to the light, I looked around and saw 7 containment units, each wider than a normal human and a good few feet taller. Something was weird though, 6 of them were completely empty. The glass on the far left was burnt through, and the one on the far left was punched through, with a bit of the containment liquid still in it. The second-to-last on the left was opened manually, and there weren't any traces of struggle, while the second-to-last one on the right was just empty, with a glowing, translucent, white liquid, full to the brim. Finally, the last empty one was completely destroyed; the ravine wall behind it was completely splattered in blood, and there were large chunks of glass embedded in various places on the wall.

I slowly crawled over to the only remaining containment unit, which was right in the middle. It had a black orb within it, which was just floating there. While looking at the nameplate of the unit, I subconsciously murmured, "Gluttony." Suddenly, the black orb started freaking out. I could hear some sound coming from it, and the entire thing was spasming. I could feel the vibrations without even touching it. "Come" was the final word I heard before my arm started moving by itself. The last thing I remembered before passing out was my arm touching the glass wall, while all the liquid drained from the unit and the glass walls fell.

'wake up... Wake up... WAKE UP!!'

My eyes snapped open, and I sprang up, looking around for the voice that woke me up. I released a small amount of mana to detect the space around me, but I didn't sense anything. Suddenly, everything that happened before I passed out rushed back to me. I turned around and looked at the now-empty 7th containment unit.

'I'm not there. Humans always look at the wrong places, looking around them but never inside. It's always interesting to witness a human's thought process.'

'Inside me?', I thought. I circulated my mana, only to find my body completely repaired, my mana veins much denser, and the mysterious black orb to be within my mana heart. I quickly looked at the containment unit again and read the name plaque.

"Gluttony..." I muttered. I looked at the other name plaques. There were Pride, Envy, Lust, Greed, Wrath, and Sloth written on the other 6 containment units. Suddenly, I remembered an article I had read a few months ago. It was written by an anonymous user, talking about how there were many hidden laboratories around the world, controlled by 3 separate organizations; the Continental Government, the Rebellion, and the Irregulars.

"What are you?" I asked. A black mass started coming out from my back and wrapped around to look at me, giving me deja vu from watching Venom a few weeks ago.

'I am the Primal Sin of Gluttony, ranked in the Top 7 among those in Hell. I was summoned out of Hell sometime ago along with the other Sins, and for the past few years, I've been alone in this lab.'

"How long is a few years for you? Like, 3-4 or.." I questioned.

'For entities such as myself, we don't think about time in such a short view. We think in centuries, even millennia. I've been in that containment unit for the past two centuries, and by myself for the past 9 decades. Today would have marked a century being alone in this laboratory,' Glutonny sighed. 'The other 6 found hosts that suited them a long time ago, which means that we should get going. Luckily for me, I found a host. The unlucky part is that since today is a new decade, our location as well as host status gets revealed. Right now, there are two in the Government, one close to the Mountain of Light, one each in the Irregulars and Rebellion, and the last two are in the Capital.'

"You don't mean the Capital where I live right? Right???" I asked. "I don't have any combat experience, I'm weak as fuck, and I have no sponsors. And from what I get, your warning me means that there is some sort of danger with you having a host currently as well as our location being so close to them. Bro, I'm gonna die. I haven't even had my first girlfriend yet, pleaseeeeee-"

'Shut the fuck up,' Gluttony groaned. 'I don't plan on letting you die when I'm just getting back to living again. And I definitely don't want to go back to that hot hellhole that I call home. Lucifer's gonna give me all of the shit that the other 6 haven't done ever since getting to the human world, FUCK! Alright, here's the plan. All you have to do is give me complete control over your body, and I can protect the two of us. Super simple. All you have to do is say yes.'

"No," I responded.

'Alright, cool- Huh?'

"I said no. I've read enough webnovels and manhwa to know that whenever some parasite fucking trash comes into the MC's body, you never give them full control. We're in this together, if I die, you go back to Hell. So, teach me. Make me stronger. Surely the title of Primal Sin isn't completely wasted on you, right? Teach me how to use your powers, and how I can kill the other 6.", I responded.

'Fucking humans. Your kind always makes our lives so much more difficult. Alright, then. What's your name, human?'

"Alex Cyatri. And you?", I responded.

'Call me Fabrion,' he responded. 'Alex Cyatri, I, Fabrion, the Primal Sin of Gluttony will sign a contract with you. The following terms will be in place till death; Alex Cyatri will be protected by the Primal Sin of Gluttony, Alex Cyatri will have his physique restructured, Alex Cyatri will grow under Fabrion's instruction, and if Alex Cyatri dies, Fabrion is given permission to inhabit his body and live in the human world. In return, Fabrion and Alex Cyatri are allowed by the Omnipotent, Omniscient, and Omnipresent to inhabit the same body in the human world. Do you agree?'

The answer I gave was something I had never been more sure of in my life. I had the opportunity to become the strongest, get my revenge, and achieve goals that I wouldn't have been able to think of without this encounter.

"I agree."
