AN: Its simple, Mc dupes. It's his ability that he got from R.O.B. And the world is RWBY. I originally wanted to do Danmachi or Asterisk War, but I'm REALLY into RWBY for some reason. Yet I haven't even watched the anime yet. I'm just going off of my knowledge of the many fanfictions I've read about this. And the knowledge equals up to about the Vale Invasion and Beacon falling. But that won't happen why? Cause Duping. Duping is life.
=-=-==-=-=-=
Arthur: "My wish is to be able to dupe anything. The world is RWBY."
R.O.B: "Nice wish, the world is decent too. And your calm, unlike those pink hair banshee, incarnates. And could I look at your memories and all thoughts too? This will be easy for me to evaluate you, It's a part of my job to write an opinion."
Arthur: "Sure."
-Three seconds later-
R.O.B: "Hoo... You are unique. You would've made the perfect soldier with your mindset. You were ready to leave your family at any second, had zero amount of love and compassion towards anyone. It even makes me want to think you lack those emotions. You constantly thought about killing, whether good or bad, family or friends, you wanted to experience the feeling of killing a fellow human by your very own hands. But something would always stop you right before. You know what stopped you?"
(AN: CRINGY AF MC)
-Arthur was now hooked. He truly wanted to know what stopped him.-
R.O.B: You lacked drive. A goal. An end destination. Your laziness overtook everything. You were too lazy to think, so you slept. You were too lazy to do school work, so you procrastinated. You were too lazy to smile, so your face became an expressionless mask. You were too lazy to kill, so you didn't. But in your new world, you can't be lazy anymore. You must find a drive, a goal. And once you do, engrave that drive into your brain, so you won't forget. Don't worry, I will help you.
-R.O.B summons a human being that is bonded by ropes.-
Rando: "WHAT! WHERE AM I, WHO ARE YOU, LET ME GO NOW."
Arthur: "Loud."
R.O.B: I know right! There are very few who are calm. People like you though, are extremely rare. Well, this is what I have to deal with on a daily basis.
Rando: "YOU BASTARDS! WAIT TILL I GET MY HANDS ON YOU, I'LL KILL YOU!"
-With a simple thought, R.O.B prevented the rando from speaking.-
R.O.B: Anyways, I'm going to give you each a random weapon. And you will then use that to fight that rando. Whoever wins lives, whoever loses dies. Quite simple.
-The omnipotent being then removes the rando's binding and summons a random weapon in Arthur hands and the randos. Arthur received a staff that was about his height (5'6) and the rando received a two-handed ax.
Without any warning, Arthur rushed towards the rando who was yet to register everything and gets a swift blunt stab to the neck which leads to the rando back up a few steps covering his neck and coughing. Without letting the rando time to recover, Arthur quickly stabbed the spear a couple times towards the rando's solar-plex, which led him into another coughing fit.
Arthur then ran straight behind the man and did a sweeping motion that hit the rando's knees. The man's knees are now bent, so Arthur uses this chance to deliver an extremely powerful thrust to the back of the rando's head, knocking him unconscious. Arthur then takes the time to drag the man towards the ax.
Now at the ax, Arthur steels himself and tries to ease his shaking body to no extent. Picking up the heavy ax Arthur swings the axe right at the unconscious man's neck, severing his head. Arthur takes a dozen or so steps back and slowly sits down on the ground to rest his body.-
R.O.B: How was it, your first kill?
-By this time, R.O.B stopped looking at Arthur's mind and truly just wanted to know. And the answer makes R.O.B smile.-
Arthur: Other than disgusting, to get all this shit on me. I feel free, like something inside of me finally relaxed. My body and mind feel more relaxed than it ever did in my entire 14 years of life. But I did get a shiver when I killed him earlier, but other than that no.
R.O.B: The reason you feel relax is because of who you are. You are fundamentally a person who will fight and fight until he dies. Contradicting your lazy nature, quite a bit. And there's no way to explain the reason why you feel relaxed. You just do, its a part of you. And the reason for the shiver is quite simple. You don't like seeing something disgusting, like the inside of someone's neck for example.
Arthur: "Ohhh. Thank you, truly. I wish you good luck in your journey of reincarnating people."
-Arthur smiles for the first time in a long time and so does R.O.B-
R.O.B: "You too. Good luck on your journey. Oh before I forget, I made an entire multiverse just for, so no reincarnates will be able to visit your multiverse. Your world travel ability will be available to you when you realize your goal. I also added a little ability for you. Good Bye."
Arthur: "Mm."
AN: His Mm mean yes or I understand. Basically, it means that he is acknowledging something.
