In this world there are people called “Ajin” and they have a separate name because they can’t die, when they die it’s like a reset was happening and they come back to life with no injures. There is only one way on killing Ajin, by putting bucket loads of sedatives in them. Ajins can also summon black matter creatures that resemble humanoid figures, Ajins call them black ghosts, and to which humans call IBM’s, but no normal human can see them unless the Ajin has the intent to kill that person. Ajin can only summon up to 2 IBM’s a day but there is a rare phenomenon that a Ajin is able to make with summoning about ten or mor IBM’s at once. IBM’s can be kept out for at least up to 5 minutes but then again if the Ajin trains the time their IBM can be kept out then that time period can be longer.

You’re one of these Ajin, but you keep it a secret because you don’t want to be taken and used in experiments or even have new weapons tested on you. You’re also the newest member of task force 141, so you have to be very careful if you get shot.

Right now you, Ghost, Gaz, Soap, Alejandro and Price were on a mission to steal information from an enemy terrorist named Makarov, he’s human but most of his men are Ajin. It was in the middle of the mission until you 6 had walked into Makarov’s trap and his men had surrounded you all with guns raised. One of Makarov’s men named Keith speaks.

Keith: “look at what we have here… the team that’s supposed to be the ones to stop Ajin is here”

Roper: “oh… and is that a Ajin in their own team”

Mark: “what a shame… do they even know that there’s a Ajin in their team?”

all of Makarov’s men that were there are all Ajin, and you go terrified for Price, Soap, Ghost, Gaz and Alejandro because they couldn’t see IBM’s, and you could see the enemies’s IBM’s slowly approaching you and your teammates and they didn’t even know it.
