Time skip

The battle has been raging for almost 5 hours now almost half of them were almost beaten down by the 666 beast.

Ozpin: our attacks ain't doing nothing against that beast!

Ironwood: not to worry my forcing will arrive here in 1 hour!

Bakugo: I don't think we'll survive that long you fucking extra!

Issei: come on you freak after I defeated you I will become a harem King!!! He shouted charging at it but then got swiped away by its massive tail.

Ozpin thought: damn it at this rate we're all dead.

Meanwhile at bread boys house

Y/n: SON! WHERE'S MY HOLY WATER!!! A voice was shouted in the house then it shows the sun running with a cup of water

Son: oh shit, oh shit, oh shit! He said in a worry tone. We have reached the basement and found his father hitting a mannequin with a hilt of his sword.

Son: hi Father here's your holy water. He says handing him the cup of water to him.

Y/n: all right but this is a test we'll see if it's real holy water! He says in a serious tone he took a sip out of the cup he's about to say something until the TV turns to the News channel.

News anchor: this just in I might as well explosion has just appeared on the outskirt of Union City and the beast of 666 has peers be released yet again. Union academy already on the situation it is best for everybody that stay indoors and get away of the fight as far as they possibly can that is all.

The two just silently looking at the TV after hearing the news, son Ben's decided to sit down on the couch and watch some anime but the TV was suddenly shot by father.

Son: father what the fuck! I just bought that TV! He shouted in frustration this is like the fifth TV this month.

Y/n: NO ANIME!?!? Oh and grab your things we're going to Union City. He said heading towards the stairs.

Son: wha-what? Why are we going to Union City do you not hear what's the news just said? He said to his father in confused.

Y/n stop in he's tracks slowly turn towards the Son and son can tell in his eyes that there's something in it that's not right.

Y/n: because son it's time I show you what are a crusader can do in a fight. Says in a dead serious tone he leaves the basement with a very half nervous son.

Time skip Izuku pov

We were defeated by the 666 beast the heroes of Union academy were all beaten or either dead.

Ruby: we failed, we're not even strong enough to beat it. She said in a sad tone.

Bakugo: damn it! I was not strong enough.

Izuku: so this is how the world ends and yet I haven't explained my love to y/n.

(Arthur note: some of these guys are chicks)

The beast beginning to fire it's last attack on us we were waiting for our death, suddenly a blast of pure light appears out of no where after the flash die down it shows two individuals. One wearing a crusader outfit and the other one who's wearing normal clothes but also a crusader helmet.

We're were stunned to see the sudden arrival of two individuals, the beast was also surprised of a new arrivals but then shook out of its state before compare its attack on it's new arrivals.

????: you have breathe your last air on this planet demon and prepare to meet your last!

The beast fired it's attack at the individuals we are already expecting for them to be killed without the bat. But what shockers is that the crusader just blocks it with he's sword before deflecting it back at the beast causing a great damage to it.

Rias: WHAT!!!! How is he able to block it and deflect it's attacks! Our attack did nothing to it and that did something! She shouted at what she just saw.

Asia: is it just me or am I seeing light coming from the these two? She said.

Xenovia: you're right Asia, I'm seen it as well it looks as if these two are blessed by God himself. She said in disbelief.

????: SON!!! I need you to blow its arms off! The crusader shouted who is barking a another attack.

Son?: Yes Father! Says the other person.

He quickly aim his shotgun at the beast then strange energy of light appear around it, then suddenly a streak of light shot out of the gun immediately blowing off two of its arms which earns him the scream of agony of the beast.

????: Great work son now let me take care of the rest! says the crusader.

The crusader quickly runs towards it we try to stop him but he somehow was faster than us, he suddenly teleport on top of the beast shoulder the beast have done regenerating it's arms and will try to swat him off. But the crusader somehow cut its hand off completely, the crusader managed to reach the top of his head before he cut the other beasts hard.

????: I am Justice! I am vengeance! I am your salvation and annihilation! The crusader shouted.

The sword on his hand begins to Glow bright so bright that it hurts some of our eyes from looking at it directly. The crusader then brought down his sword on top of the beasts head cutting it clean in half. Which caught us completely by surprise by the event play out before us.

The crusader then caught the beast on fire burning the body into Ash. The crusader then turn back towards his son.

????: Well son our job here is done, let's get going and get something to eat.

Son: all right let's go I'm starving.

The two begin to leave then stop by headmaster ozpin.

Ozpin: hold it right there you two who are you and how are you able to do that. We don't recognize you as any heroes we know. Ozpin says in a unsure voice.

????: Fuck off. He said before slamming him on top of a table.
