Somewhere in Universe 6
"Another target eliminated." Hit says as he exits the building without being noticed. His client was waiting for him in the forest near the building where the target was. The assassin finally arrived to the forest. "Is it done?" The cloaked man says.
"The target has been eliminated" Hit says. "Great, I knew you were the right man for the job. Here's the payment" The man pulls out the money and hands it to the assassin.
"It's a pleasure doing business with you. I shall be going now." he says as he flies out of the planet at high speed. Later on another planet, he decided to take small break and have some tea. After he finishes, he looked at his next request.
"What's this? A list ?" The request was from a unknown person. "Suspicious.." There was a note and box that came along with the list. "Hello Hit the famous assassin from Universe 6, I have a load of pests I would like for you to take care of. I even had a device prepared for you in the box. You see, these pests are not from the universes you know of. There are universes that the gods, angels and even the omni kings didn't know exist. This device will allow you to travel to them where the pests are. The list will have their names and appearances on what they look like. If you kill all of them, I will promise to give you your payment".
"Other universes? Hit never knew there were other universes besides the ones he knew. "This person seems to know the omni kings too" There are many things strange about whoever requested this but he isn't gonna decline. He doesn't do it for the money but he will fullfill his contract no matter what.
Hit opens the box and sees a strange device that resembles a watch. "This must be that device" as he wears it on his right arm. He wondered how it works. Suddenly, it glows and a screen popped up above and showed a bunch of names. He then looked at the first name of the list.
"Elsa Granhiert.." He looked at her appearance and tried to search which universe she's from on the watch. "The re:zero universe" The watch says. "Interesting. I'll take this one on".
"Would you like to go to this universe?" Hit presses the yes button. The next thing he knew, he disappeared. Now he was somewhere else.
