[Izuku Pov]

Today was the day I was going to the Aggressive Tea Bar to become a contracted assassin.

???: so, you must be the Green Demon.

Izuku: How did you figure that?

???: I did request him to come here, plus, you seems like his height, the name Greg Daniels.

Izuku: I'll only tell you I'm Green Demon.

Greg: It's ok, and understandable, anyway, the contract is that you'll gotta work for me and then, I'll give you a paycheck.

Izuku: how much?

Greg: $100,000 after each contract assassination completeion per day.

Izuku: Sounds Good and Fair.

Greg: Yep, even though I was a former assassin like you then after the years, I retired.

Izuku: How many have you killed?

Greg: Hundreds, thousands maybe, even Unionies.

Izuku: I see, you're a man of Anti-Union as well, I hate those heroes.

Greg: what did they do to you?

Izuku: Neglected by my "heroic" parents, bullied and abused by my "heroic" sister and her "heroic" friends, dumped my ex-girlfriend, and most likely they all will be attending Union by now.

Greg: Damn, that's rough. Never trust any fake heroes like those fuckers.

Izuku: Damn right. So, who's the target?

Greg: This Guy...

Izuku: He seems like an enforcer type.

Greg: It's because he is; he works for the Schnee Corporation as their private army, they go to Towns and Villages of Faunus and Monster-Girls and put them into the mines, doing illegal forced labor.

Izuku: and those heroes allow this?

Greg: It's because Jacques is falsely feeding them information, telling them that they are working there willingly.

Izuku: Fucking Fools.

Greg: so, you'll take this?

Izuku: Oh yea, I'm definitely taking this.

Greg: Good, see you when it's done.

After that, I left to head back to my hideout in the city.

[Timeskip]
[No One Pov]

Outside of the warehouse of the Schnee Private Army, we see Izuku aka Green Demon standing on the roof across from the warehouse, wearing a new suit that he created.

Izuku: Alright, let's do this, Soundless Barrier.

The outside of the warehouse was put into a barrier, so that no one outside could hear what was going on inside, plus, it blocked any to all communications.

Izuku teleports himself within the warehouse and hides, as he scans the warehouse.

Izuku: 8 Enemy Combatants, 10 innocent Civi's, including the Leading Enforcer.

Izuku then summoned his suppressed combat rifle.

Izuku: alright, Going Dark.

And then, Izuku became completely invisible, concealing him completely.

Izuku pointed his gun at one of the enforcers henchmen's head and silently shot him in the head.

Another enforcer's henchmen approached the dead henchmen, only to be shot in the neck, but not before shooting his gun, alerting the others.

Izuku: shit.

Izuku moves to hide as two more enforcer henchmen appear, searching, but then Izuku appears behind one and pulls out his combat knife.

Henchmen: where are you fucker?!

Izuku: Nowhere~.

Before the henchmen could even turn, Izuku plunged his combat knife into the man's neck, as he was bleeding out while Izuku was silencing his screams.

Izuku then pulls out another knife and throws it at the henchmen across from him, as he was stabbed in the head, killing him instantly.

Enforcer: Remaining Henchmen, Form on me!

Henchmen: Yes sir!

Izuku sees the remaining four henchmen form with the Enforcer as Izuku jumps down to their level and lands, before becoming visible again, displaying the blood of the other henchmen on him.

Enforcer: who are you?

Izuku(GD): You don't need to know such information.

Henchmen5: Yes, you will!

As henchmen 5 lunges towards Izuku as he was standing there, before he shoots black whip out of his suit and plunges into the henchmen and throws him away.

Henchmen6: N-No way, That's the Green Demon!!!

Henchmen7: You have got to be kidding me!

Izuku: Now, You will pay for mistreating these innocent people.

Enforcer: People, they are nothing but freaks of nature, humans are the rightful rulers of earth, nothing more nothing less.

Izuku: tch, scum like you don't deserve to live.

Henchmen8: you take that back, you bastard!

Henchmen8 lunges towards Izuku followed by Henchmen 7, as Izuku pulls out his pistols and shoots Henchmen7 in the head, as Henchmen8 was shot in the legs, before the neck.

Izuku: You're losing men, Enforcer.

Enforcer: I'll deal with the so-called Demon.

Henchmen6: B-But sir...

Enforcer: Get out of here.

Henchmen6: O-Ok, Sir...

Before he could finish, Henchmen6 was shot in the head as he dropped to the ground, as the Enforcer turned to see Izuku pointing his gun.

Izuku: Cant have an enemy witness now, don't I?

Enforcer: You bastard!

The enforcer lunged towards Izuku with his greatsword in his hands as Izuku summoned his own greatsword, as the two clashed.

Enforcer: why do you side with those freaks, we know your human!

Izuku: formerly human, I removed my humanity because of how much I despised them for what they have done to me.

Enforcer: what have we ever done to you?!

Izuku: not just me, but more like me, the powerless, the true human race, not you superhuman scum.

Izuku then headbutt the enforcer, knocking him off balance, before kicking him back.

Izuku: humanity was disgraced like a forgotten memory by your supers, everything humanity has accomplished was instantly forgotten and degraded within 300 hundred years, humanity would be better, if powers were never around.

Enforcer: Y-Your insane, without powers, the grimm would run without supers like us, without heroes like us! Without us, this world would be long dead!

Izuku: tch, heroes like you are fucking scum, you bring nothing but suffering to everyone, imagine the news discovering the truth of heroes, if people discovered who created me, what "heroes" created the Green Demon you see today.

Enforcer: No one could ever create a villain such as you.

Izuku: Hero, Villain, they're nothing but mere children, playing with their toys.
(Reference?)

Enforcer: Shut Up!

Enforcer lunged full speed at Izuku as Izuku pulled out a sword, which was switched from his greatsword and plunged into his chest.

Izuku: You'll never change, no matter what.

Enforcer: W-Who are you, behind that... f-fucking mask...

Izuku: someone the heroes will wish never gave birth to me, especially the Number 1 and Number 12th Heroes.

The Enforcer's eyes widened as he was trying to say his name, but his eyes turned dull and he died, as Izuku dropped the enforcer on the ground.

Izuku: alright, time to free the prisoners.

Izuku then went over to the cells as he opened them all as the Faunus, Monster-Girls and Powerless Humans ran out.

Izuku: here.

Izuku opened a portal to Monsters Island as the Faunus, Monster-Girls and Powerless Humans went into the portal and appeared on Monsters Island.

Izuku closed the portal and opened another to the Tea Bar, as he stepped through.

Greg: so, it's done?

Izuku: Yep, The Enforcer is dead and the slaves are free, on monsters island.

Greg: Good, as promised, $100,000 will be sent to your account.

Izuku: Thanks.
