2 What?

Sam was in a pitch black space with nothing going on but him remembering what happened before this. "God damn it. I died from a fucking snowball" Sam said as he remembered that a snowball that was tightly packed, came flying at him and hit him. It caused him to fall off the bridge on the way to work. "Well, this isn't hell so I guess I did something right" Sam said to himself. Several screen pop ups came and went really fast until a final screen popped up. "Do to you having null karma for 420 lifetimes. The gods have decided to all give their blessings and it caused a balance crash on the god system, The system fused all of that divine power and granted you the power of [Unity] which grants the user to use any bloodline possible and for multiple bloodlines to work together even if you use opposing bloodlines. You were also granted a gacha system. Expelling you to a random universe" The system said before he blacked out. 

Sam woke up on an altar on top of a tower and had no clue where he was. "Ha! I summoned something!" a female voice said that sounded familiar. "How could a fat chest elf like you summon something like this? I obviously summoned it" Another very similar voice said as Sam recognized the voices. They were Rem and Shera. "The user is too powerful for the slave charm and reflected ot to them. The plot and other items are changed to the user. Please customize your bloodline" The system said. "Ok, if i can have any bloodline and power. I want rimuru, all black, ghost rider,  Infinity dragon, Meleodus's bloodline, Estarossa bloodline, and Demon God'' Max said as the system popped up and he felt a surge of power. "Synthesizing Rimuru  and All black. Result was All Black outer god slime at 30%,Lets users use all abilities from Remiru and All black. Infinity Dragon is set at 5%, letting users have infinite magic and stamina. Meliodas a Estarossa lets the user have the strength and agility of a level 200 user and access to  full counter for both magical and physical attacks, set at 10% total. Demon God gives access to all abilities and lets the user be classified as a demon lord, set at 40%.  Ghostrider will give users full access to his abilities and set it to 15%. User has a beginners package. User gained [Unity Magic User] [Unity Fighter user] [Heightened Gamers Mind] and [Quick Learner].

[Unity Fighter User] lets the user use any martial arts if the host knows how to do it and it has no restrictions. [Heightened Gamers Mind] lets the user be completely immune to mental attacks, including one that is being implied by a bloodline unless the user wants it. [Quick learner] lets the user learn how to use magic or skills just by watching, the more complicated the more he has to see" The System said. "No, he is mine!" Shera said. "No! Mine!" Rem said as they continued arguing.  "Stop" Sam said as they stopped yelling and looked at him. "Wow, a summon that can talk! I must be a very good summoner" Shea said as she crossed her arms under her big chest. "Let's test it. Let's give it one command and whoever it follows is its summoner" Rem said as they faced Sam. "Raise your hand" Rem said and Sam didn't do a thing. "Ha, that means he is my summon. Bow down to me" Shera ordered Sam and he didn't do a thing. "Sit" Sam said as Rem and Shea were forced to sit down and a metal collar appeared on their necks. "Nooo. the slavery spell backfired" Sara said asshe teared up. "This is impossible. This hasn't happened before" Rem said as she was shocked. "Lisen, i'm going to set out the rules. No stabbing me in the back on your own free will. No telling anyone of my abilities unless I show them to the public. And I will do whatever you summoned me for" Sam said. The two were wide eyed and looked at eachother. "So, you won't order us to do anything else? You sound like that all you are going to order us to" Rem said. "Well you two are cute but regardless of what I am I don't really like forcing people to do things. I'm helpful when I want to be" Sam said. "Oh, my apologies. We forgot to ask you your name, I'm Shera Greenwood and ignore the fact that I share the name with the elven royalty. Um, I want to be a summoner to travel and enjoy my freedom with" Shera said. "I want a powerful summon to defeat an enemy of mine" Rem said with a downcast look. "I'm Nexus. Pleasure to meet you. Shera, please wait for us at the bottom of the tower. I need to talk to Rem,"Sam said. Sam decided to change his name as Sam doesn't sound right in a fantasy world like this one. She had a disappointed look but went down stairs like she was asked to. "What do you want for me?" Rem said as she grabbed a few of her summoning crystals. "Is your enemy the demon lord inside of you?" Nexus asked and Rem jumped back as she threw 3 summon crystals but they never hit the ground to break as Nexus caught them with his speed. "No need for violence. I just sense a demon lord inside of you. I can help whenever it leaves" Nexus said as Rem realized there is no point in fighting him. "Ok, but how can you sense it?" Rem asked. "I am a demon lord as well. Actually I guess I'm a demon god. But don't worry. I have no intention of interfering or killing mortal lives"  Nexus said which greatly surprised Rem and put a lot of fear in her. Nexus handed Rem her summons and went down the tower.
