The Guardian

USJ: 'Demon unleashed'

Izuku: "remember...you chose this" as he said this to the villains in front of him...they all laughed 
"are you kidding? it's 21 to 1" 
Izuku: "yes...see your mistake?" and they had enough...but as the first one was about to attack Izuku in one quick motion throws the chain to grab the villains arm and toss him aside...as he rushes in he uses the Masakari to swing widely hitting three more...
"FUCK!" as he then throws the axe...it went into one of the Villains head...killing them
"no way.." 
"he....he killed him!" 
"he's not fucking around gah!" as Izuku smashes him with the Kanobo...some ran...while others still tried to fight...swinging it over head he then reels the chain back in to pull the other villain into the others trying to rush him...
"TAKE THIS BITCH!!!" as he throws his Masakari back at Him...Izuku without looking catches it...
Izuku: "hmph" and they froze from this...and he now holds both weapons...as he slides on the ground he sweeps the Kanabo underneath one villains feet knocking him down...as he drives the pommel of the Masakari into another...hearing them scream he ignores it...as he kicks the axe in further he swings the Kanobo on the sharp spikes on them and he kills the other villain...and he was punched away by a large one...as he tries to go in for a left hook Izuku dodges...rolling back he then brings out his Chakrams...Throwing it it hits the side of his neck causing him to grip it tightly...but he goes in to slash him across the chest twice...as he regains his composure Izuku just stands there staring at him
"Ugh...YOu...Little!" as he was about to grab him the Chakram he threw came back and lodged itself into the side of his head...and he falls forward...pulling the Chakram out and he puts it away...seeing the villains dead or knocked out...he turns to see one left...who was frozen throughout the whole thing...He tried to run But Izuku Throws the Kanobo hitting the back of his leg making his flip on to his back...as he groans in pain he tried to get back up...but the Kanobo was then planted onto his chest...preventing him from getting up 
Izuku: "who sent you" he asked him....he remained quiet not wanting to give any information out..
Izuku: "Your testing my patience...if it involves putting the innocent at risk i will have no other choice but to free your Miserable head from your miserable shoulders" 
"NO...He...It's Shigaraki...he...he told us this was going to be an easy job...." 
Izuku: "what is your mission" 
"To kill as Many students to draw All MIght out...please...that's all i know " hearing him cry out...Izuku then lifts it off 
Izuku: "you still haven't shown intent...for now...you will be spared...but if i see you again...you will die" and with one kick to the head he knocks him out...if he was caught in that portal he needs to find the others!...running up to the exit he then grips the doors...and forces it open now...now he heads towards what seems to be...
Izuku: 'the mountainside Rescue scenario' 
Ochako: "HELP!!" 
Izuku: "OCHAKO!" and he runs faster as the villains keep on rushing through the area..

Ochako: "no" as she was trying to keep Mina up...injured from the fall...the area they're in is extremely cold...
Mina: "where's...where's sero?" groaning out...as they see him unconscious behind them the villains only got closer 
"come on now...we'll treat you nicely" 
"you'll fetch a pretty price...especially that skin of yours" looking at mina 
Mina: "oh god" 
Ochako: "HELP!!" screaming out again...as one of them got closer..about to grab her...his hand stopped inches away from her...to see a chain was wrapped around his neck...and he was pulled back as they other villains watched him fly back Izuku then stood there and stomped on his face...
Izuku: "Kept you waiting huh" looking at them...only holding the masakari...one of them charges him and he blocks the attack and then lodges the pommel into his mouth before ripping it out...one of the villains had a quirk allowing him to shoot ice spikes at him...he deflects it and then in a graceful motion slashes the other villains gut clean open...and then slams it into the next ones head straight down....ripping it off he deflects another spike and he throws the chakram and it hits his neck making him grip it and he activates the device pulling the chakram out...as more keep on coming....he then kicks another and as he swings the axe he turns it at the last moment slamming him with the side of the Masakari making him launch back...knocked out from the force in that slam...as he looks around to make sure no more was coming...Izuku turns back to look at Ochako and mina...who in complete shock of what just occured 
Izuku comes up to them: "come on..we need to go" 
Mina: "get back...no..." whimpering out
Izuku then looks down at himself...seeing the blood....and the corpses behind him...
Ochako: "You...you killed them" 
Izuku: "I know...but i need you to trust me right now...more are going to arrive and i may not be able to protect you...let us hurry" as he leads the way...Ochako and Mina see him carry Sero...checking out in the hallways...Mina was now able to walk a bit 
Izuku: "I need to check up on the others...I need you to use your quirk and take Sero back to the entrance...okay?...I'm going to try and get everyone else gathered up...alright?" Ochako nods...but...she still couldn't believe in his ability
Izuku: "Come on...snap out of it...remember...get them back and i'll try to get the others...go go!" Ochako; "RIGHT!" and they head off away following the signs...as Izuku now starts running in the other direction...seeing the next scenario coming up...the fake city...he looks to see Katsumi and the others...taking care of the other villains...so he knows they have that...he continues on and he sees the next one...the Overseas rescue Scenario as he looks overhead to see Tsuyu and Mineta trying to fend themselves off...well mainly Tsuyu Mineta just threw balls wherever...Izuku now goes in and he slowly sneaks up behind one of the villains...and he swings the Kanobo around and then slams one of them out of the way into the water...as he rushes in he throws the Chakrams and it hits another villains neck and he slides down knocking another onto their back and he slams the Kanobo down on him...knocking the wind out of him hearing the villain gasp for air...throwing the chain to catch another and pulled him back and he tosses them into the water...seeing him kick another back and he then throws another Chakram and it hits the villains hand...he now presses the button to his support gear and both Chakrams come right back and hits another two...this display of skill..is unbelievable...Tsuyu and Mineta could only watch...as they see this Guardian...Attacking like a demon...but guards like an angel...to ensure no harm befalls on them...
Izuku: "HYAH!" spinning around sweep kicking another villain on the ground as he throws the chain and it stabs right into a villains chest...Izuku now pulls with all his strength
Izuku: "COME HERE!!!" and as he was flying towards him he uses the Kanobo as a way to clothsline him with it...and he stomps on the other villain...knocking him out...
Izuku: "GO!!" and with that he snaps them out of their focus...and they start running...he continues his onslaught...as some of them tried to run...and then he was jabbed in the side...with an iron rod 
Izuku: "GAH!" the villain got him in a part of his armor that wasn't very well protected...but he grips it and then slashes his neck with the Chakram...and he bled out...seeing him squirm into the ground...Izuku ended his pain quickly...slamming the Kanobo down which instantly killed him...now he has one more area to look for...he can feel the others are able to fend themselves...he'll have to find Aizawa...now exiting the area he keeps on looking for a way back to where he was...while facing the occasional villain along the way...only using the Masakari he jumps and spins to slam it down onto a villains armored vest...which got caught he then started pushing making him fall back and then with a quick motion flips over him and then grips the hand to slam him into the ground overhead...knocking the axe out of the vest...and he continues...seeing more ahead of him...one of them tried to fire what seems to be fire balls at him...using his chain he starts spinning it while running to disperse the flame before it even hits him...seeing the ambers rushing past him...looking like some other Beast that cannot be stopped...even if they tried...it was no use...then his scarf from the end of it was burning...but he didn't care...which only enforces the idea of him being the Demon Guardian...the Protection of a Shugoki...Merciless as a Hitokiri now making his way through a door...he makes it back to the area he fell through...
Aizawa: "DAMN IT!" seeing him trying to fight this giant beast like thing...seeing other students now coming out from the other doors...he throws the chakram and it hits the beasts head...scraping it's exposed brain 
"Hmm...how interesting" seeing the leader taking interest in him...as he jumps and slams his Kanobo down on him...it had no effect 
Izuku: "what!?" and he smacked off...dropping the weapon 
"HAHAHAHAHA...Such a foolish hero...you think you can topple against the very thing that will kill All Might!...Feast your eyes...On NOMU!" and the NOMU again roared as it picked up his Kanobo...Izuku takes his Masakari out...
"Say good night hero...NOMU...Kill him" 
Izuku: "heh...I'm no hero" and he starts running towards it...and then...both weapons clashed...in the battle that is to come
