The Guardian

A martyrs Oath

as Stain now takes a defensive stance...the hero and guardian await on who will make the first move...Izuku then takes the time...to close his eyes...and focus...remembering what Okuma taught him...
Flashback 
Izuku: "why do i have to close my eyes?" 
Okuma: "Because...this way you can concentrate on the sound...if you hear one movement too late...it won't bode well...now...try again" as Izuku puts the blindfold back on...holding the bamboo stick steadily...he waits for the attack...and like Okuma said...he now swings his stick on the right...hearing the bamboo whistle...Izuku now deflects it...and he does it again this time overhead...and he hears it again...deflecting it once more...
Okuma: "good...you are doing well my boy" as he ruffles his hair Izuku laughs 
Izuku: "does it mean i'm getting better!?!" 
Okuma lifts him up: "You bet you are...and i'm certain you'll be just as great as All Might" 
Izuku: "You really think so?" 
Okuma; "I do" and Izuku cries out..and he hugs him...as Okuma chuckles from this
Flashback ends 
Izuku now hears it...the sword hitting the ground slightly..opening it to see the hero killer going straight for Ingenium...as he throws the chains...Ingenium deflects one sword while the other was wrapped around with chain...Izuku charges in and he then plants the Masakari into the ground and he kicks him away...rolling now he throws the Chakrams at him...pushing Ingenium aside...he now charges full on at him...Stain now getting up deflects the Chakrams..only to lock blades with Izukus Masakari...both now standing off
Stain grunts as he can see the amount of strength this boy has...but he's not fast enough...as Stain now goes into a full barrage of attacks...seeing Izuku trying to deflect some of them...even so much as to spin his chain which ended with it wrapping around a sword and he kicks him away...Ingenium using his quirk tried to help out...but Stain then swings overhead...hitting his helmet...
Ingenium: "what the?!?!" checkinghis helmet...about an inch away from his neck...
Stain now tried to go for another jab...but something unexpected happened
Izuku: "HYAH!!" charging in like a bull he grabs him...and he charges into a brick wall...destroying it...switching to his Kanobo he then swings it upward...making the hero killer go through several floors...
Ingenium: "jesus kid...didn't have to be that brutal" 
Izuku: "less talk come on!" as he leads the way up...heading to the rooftop with the occasional scared resident for destroying their homes...Izuku now sees the Hero killer sitting up on the vents...brushing off the dust on his shoulder 
Stain: "such a brutal fighting technique...no wonder they call you demon" 
Izuku then charges in with his Kanobo in hand...as he swings it overhead Stain rolls out of the way...seeing the Kanobo plant into the roof...he had to let go...trying to avoid a slice...to Ingenium coming in to land a punch on him...but he avoids it and accidentally hits Izuku instead...knocking him back 
Ingenium; "damn it!" and he dodges another attack...using his quirk to charge his attacks...Stain then flips on over to throw one of his swords...and Ingenium catches it and he does an uppercut to hit him...as he falls back Izuku now picking up his Masakari goes for it...and he does his Bulls charge...flipping him over and he tried to slam the Masakari down...but Stain managed to cut his leg...but he ignores it and he rolls out of the way...with a quick effort he slams him in the face with the side of the Masakari while Ingenium now jumps ahead and hammer smash him down through the roof...both breathing heavily...as Izuku looks at his cut...but he ignores it 
Ingenium: "you good?" 
Izuku: "for the time being...where is he" but out of nowhere...he felt the same pain in his heart happening again...
Izuku: "AAGH!" 
Ingenium: "oh crap you alright?!!" but then...Stain comes out from the debris to now begin attacking him 
Stain: "how convenient" as he continues on to  fight him...Izuku tries to get back up...but...the pain was overbearing for him...that same burning sensation he had back at USJ...as he tries to get up...Stain now managed to cut Ingeniums hands...
Stain: "now then..." as he licks the blood of his blade...
Ingenium: 'what is!?!' now losing all motor functions...he couldn't move a single muscle...as he was literally frozen in place...
Stain: "my guess is B...it'll take a awhile for you to get out of my grasp...but sadly...you have no more time
Izuku: "no!" as he then tries to get up once more
'the oath of a guardian is to protect the people' 
trying to get up again as Stain slowly gets closer to Ingenium 
'the save those who cannot fend themselves' 
Izuku: "fuck!" as he now managed to get up...he stumbles towards them 
' even when you have this oath...to protect the innocent' 
as Stain now positions his sword...
Izuku: "FUCK!!" as he now fought through the burning feeling 
Ingenium looked at him...and he could only smile through his helmet...
*stab!* 
'Know you cannot always save them' 
Izuku stopped...as he fell over again...watching the hero killer...stab Ingenium in the chest...as he stood there...and yanks it out...he felt it...
Izuku now grows...as his skin slowly turned red...
Stain: "hmm" 

Izuku: "HYAH!!!" as he rushes at him...Stain dodges but to his surprise Izuku feint the attack and then he grabs him by the leg...even when he managed to stab his abdomen
Izuku: "GRRR!!" as he looks at him dead on in the eyes...Stain could see...all the hate..the anger...the primitive rage that has build up in him...as he was slammed into the ground multiple times...and then tossed aside...like he weighed nothing...grabbing the Kanobo out of the ground...he jumps up and he screams with all he has to try and slam it down on him...but by then it was too late...for stain now dodges again...as Izuku now holds the Kanobo in a form...he is full focused...
Stain: "now i see why the heroes are manipulating you...you have no bounds to your strength boy...such a worthy adversary..willing to kill...to act out for anothers vengence...taking everything loss to heart..." 
Izuku: "I'm no boy...I...Am Izuku Midoriya...the son...of...FIREDRAKE!!" as he now charges at him...the burning sensation can be felt throughout his entire body..but he didn't care...as he and Stain exchange blow from blow...as the swords chime in the wind...the Kanobos earthshattering strikes...the moon casting over them...like it's a duel between two demons...two warriors...as he then sweeps the Kanobo underneath him he rolls out of the way...throwing the Kanobo he then swings the Masakari from underneath him...spinning now two see the blades collide...seeing the sparks fly off as he continues to battle him...
Stain: 'the son of firedrake...he is bound for greatness...or for a great evil...should the anger takeover....' as he then swings the Masakari again colliding with his swords..one of them broke...the blade flying off...as Stain now winces at this...seeing him act out like an entire different being...swinging overhead to feint into a jab with the pommel to then kick him back to to try and behead him...but it wasn't enough..as at the last bit...Izuku felt his heart burn once more...and he stops 
Izuku: "hgh...gAH!!" as he stops...Stain now taking the lead...and he kicks him down...dropping his Masakari he looks up to see a blade just inches away from his head...
Izuku still clenching to his chest...had no words to say...only closing his eyes...awaiting the final blow 
but to his surprise...nothing happened...and he opens it to see...Stain gone...without a trace...now seeing he made his escape...he had to check up on Ingenium
Izuku: "no" as he gets back up...he tried to rush to the knight...as he tried to put pressure on his wound 
Ingenium: "kid" 
Izuku takes a look at the wound...and he can tell he's already called out for help trying to take out a piece of fabric to rip off and hopefully help him
Izuku: "no...no i need you alive...you can't die now...not when the people need you" 
Ingenium: "i...there's no time...." 
Izuku; "just hang on a little longer...your going to see lida again...remember why!" 
Ingenium: "Guardian...can...can you promise me one thing" 
Izuku knows that it's too late...he won't have enough time...he had to hold back his tears...even if he's known him for one day...a life...is a life...the same happened...when he cried out...for those who were killed in USJ...the guilt of taking their lives...but...now he is at fault...failing to save another...when it was his oath to begin with 
Ingenium: "G...Guardian" 
Izuku: "anything..." 
Ingenium: "take....take good care...of my brother...please...make....make sure he doesn't...do anything..s...stupid." 
Izuku: "I will...i Will" as he couldn't hold it in anymore...Ingenium smiles 
Ingenium: "Thank you" before closing his eyes...for Stain had gotten what he wanted...the death....of a martyr
