Prologue

This story starts in a world devoid of any light. A place that many refers to as the void. A place where many of the lost souls could be found, floating silently in the pool of darkness that was this area. One of those souls in particular was about to experience something that many dreamed of.

This soul was just floating aimlessly in the void when a sudden light appeared in front of it. Said light was so blinding that it could illuminate the whole void, but it only lasted a few seconds. And in those few seconds, the soul disappeared.

****************

( World of Attack on Titan, Wall Maria )

Morning came for the humans behind the walls. As the first rays of sunlight appeared, the citizens started to wake up, while the soldiers of the Garrison started their patrols. But not a single person was aware of the incredible thing that had just happened.

On the wall maria, a portal had appeared. And from this swirling black portal, a young man fell. A man like no others. For he was dressed in clothes that no one in this world possessed or had ever seen. But this wasn't even enough to prove that this man didn't belong here. What really proved it was the two things that he had in his hands. A cellphone and a sniper rifle. Now one would wonder what a man like that was doing here ?

Well as the man's eyes slowly opened, looking around in panic, it seemed that he too had no idea of what he was doing here. The man looked at what he had in his hands and immediately dropped the sniper rifle while gasping.

" W-What....What am i doing here, with a sniper rifle in my hands?!" Asked the man rather loudly, before he looked around once more, finally noticing that he was on a fifty meters tall wall." Where the hell am i ? Wait ! Who am i even ?!" Yelled the man. He quickly brought the phone to his face, and used the screen of said phone to see his face. He was a rather plain looking plain, but he was a bit chubby and had incredibly bright blue eyes. His long black spiky hair were donned in a ponytail, while a few wild locks hanged on his forehead, he also noticed that they were a bit greasy. Looking down, the man saw that he was dressed in a plain black shirt and a black and white short that reached to his knees. He also wore some black sneakers on which was a brand symbol that he couldn't recognize he felt that he had already saw it somewhere.

After looking at his face once more, the man began to panic even more than before. Which was normal considering that he couldn't even remember where he was, what he was doing here.....Or even who he was ?!

[ Well i could answer this answer, user ]

" What ?! Who talked ?!" Asked the man, surprised that someone had talked when he was sure that there wasn't anyone around. " Where are you ?!" Asked the man, after he had checked that there was really no one around him. But he didn't receive an answer, instead the phone that he had in his hand began to vibrate. The man looked at it and gasped when he saw that the interface of the phone had changed. It now looked like a game interface, an rpg to be more precise. With a lot of things, like the inventory, the settings, the quests or even something called gacha. For some reasons the character screen couldn't be found.

[ Allow me to introduce myself, user. I'm the Muliverse Gacha System, or just MGS. I was created by a primordial being, the same one who sent your soul back in your body and then sent your body in this world. I could tell you why you were sent here, or even why i was given to you to aid you in your quest, but we don't really have the time. A group of human is heading this way. So i will just tell you something. As you probably already noticed, you don't have any of your memories. You remember absolutely everything about your old world, except for the memories of your own life, and that's better, trust me. You were sent in the multiverse to live a new life. One filled with adventures and dangers, and you will absolutely love it. For now find a place where you can be alone and i'll explain the rest ]

While the man was a bit confused, he did remember what a gacha was, or even what a system basically was. He remembered that some stories back on Earth had those systems, but he couldn't remember any of the stories he had read. However it wasn't the time to think about it, because he needed to find a way to get down from this freakishly huge wall, which strangely enough was quite familiar.

[ Jump ]

" What do you mean, jump ?! You can't seriously expect me to jump from such height ?! I might now remember who i am, but i'm pretty sure i can't survive a fall like that !!!" Screamed the man. But he didn't get any answer, and once again the phone vibrated. This time there was a direction sign that pointed to his left. The man turned around and when he saw that the direction sign now pointed right in front of him, he walked until he was on the edge of the wall. That's when he looked down and saw an enormous stack of hay. It didn't take him more than a few seconds to understand what it meant, and he suddenly shook his head as fast as he could.

" Absolutely not!!! Even with that huge stack of hay, i'm pretty sure i'm gonna turn into goddamn mash potatoes once i land !!" Yelled the man.

[ Do not worry about that, user. As this is only the beginning, i will help you a bit ]

" And what do you mean by tha-ARGHHHH!!!" The man didn't have the time to finish his sentencethat an invisible force pushed him and sent him hurling towards the ground at a frightening speed. At this moment there was only one thought in his mind. He was gonna die for sure, and he didn't even had the occasion to curse the system.

But luckily, just as he was about to hit the ground and most certainly turn into paste, he began to float slowly. Opening his eyes, the men let out a sigh of relief as he softly landed on the floor.

" While i'm quite happy to still be alive, why did you show me the stack of hay if you were gonna do that ?" Asked the man, though he wasn't ready for the answer.

[ Because you wouldn't have trusted me. So i just showed you that to make you sightly less stressed.]

"....."

[ Anyway, i'm not called a Gacha system for no reason. As you most likely know, a gacha system would allow you to summon pretty much anything and your drops would depend on your luck, and only your luck. By using the Gacha you can get pretty much anything, be it equipments, skills, perks or other things that could help you. Those drops have ranks, which are tiers, going from Zero to Ten. You can only obtain something from a certain tier by being at this tier yourself. You are currently tier Zero, so you can only have tier Zero drops. But do not worry, for this rules only apply to normal gacha, which you can use everytime you complete a quest. As you are a beginner you can use a special gacha that can give you anything from any world in the multiverse, be it a Tier Zero trash weapon to a Tier Ten stupidly powerful servant. Also remember this, no matter what you get as long as it's the same tier as you , you can only have it one time. Per example if you are tier four and get a tier four servant, you will only have this servant. But if you were to drop a tier three servant, you will get copies of it. By the way even if you are just Tier Zero you can get copies of tier Zero drops, because they are basically trash ]

" Next time please explain things one at a time, that's just too much informations to take in. But anyway, i will just use the special gacha. " Said the man, as he searched for the special gacha, and after he found it, used it. The screen then showed some sort of roulette on which was many parts. Be it equipments, servants, buildings, skills, perks, pets, companions or just whatever you could think of, it was in it. The roulette started to roll until it stopped and the arrow pointed at servant. Then his prize was shown on the screen.....And the man fainted.
