Fluxion, SOME grammar cleanup (no offense meant daisy!)?! Sorry this is 12 days late...
1. "...traffickers. Riley..." (the ...s are skipping unnecessary text) this is more of a suggestion than a fact it needs fixing, but I still think you should put a period there and not a comma.
2. "...supposed..." Sopposed is spelling it wrong.
3. "...school of heroes..." I would normally skip this because you could be referring to the schools by the name school of hero (even though I find that a tad odd) but earlier you say "...villains..." which suggests hero in this part should also be plural. Also, I know heroes looks wrong and you may be tempted to write heros but if I didn't mess up somewhere heroes is the correct spelling for hero plural.
4. "...if your lucky..." Is supposed to be (the quotations marks doesn't mean it's an actual quote!) "...if you're lucky..."
5. "...just cause..." This is because, but I understand lots of people (me included) use 'cause but you need to have the ' at the start or it's cause as in it caused the storm.
6. "Hero are rare..." Again, it's heroes.
7. "...who goes..." Who go, not goes. You shouldn't change tenses in one paragraph (I'm working on staying on one tense too).
8. "...heros..." You use plural this time, but it's heroes not heros.
9. "... to me'..." (I used ' where you used " because it was already inside quotation marks) it's to me? You forgot the punctuation.
10. "throw a bucket" is supposed to be throws a bucket.
11. "...'wash..." it's Wash, you forgot to capitalize.
12. "...palace'..." it's palace. (with a period! The period isn't me ending my sentence, it's me putting a period after as a correction).
13. it's myself, not my self.
14. "...outfit it a..." it's "...outfit. It is a...".
15. "...bruises and jeans..." should be "...bruises, and there's jeans..." or you could just do "...bruises, and jeans..." because the way you have written it it can easily be misinterprited as the jeans are covering the bruises. Unless that IS what you mean and I got confused...
16. Like Fluxion said, this part with the sun and sky need a lot more text.
17. Maybe describe the car more like talk about how dark tinted windows and blah blah blah made you feel intimidated or something.
18. "...inside the..." should be "...inside. The..." or "...inside, the..." Also maybe write an actual conversation between the three slaves.
19. "...other two slave..." should be slaves not slave.
20. I'm confused about the last part... you mean kids around a stage? The kids are the stage?
Also, this is way too short even for a short story. You should add more at the end, and if you're going for a cliffhanger there's not enough tension or suspense. Also, you haven't even finished the exposition as I have no feel for the characters or the world. Ok... there's some school of villains and heroes and... I don't understand any of the things the character seems to. If she's also confused, make that more clear. You need a lot more world and character building as right now it's almost non existant.
