issei was approached by two people and what made this unbelievable is that one of these two people were Sirzechs Lucifer and his wife Grayfia Lucifuge he could feel the power rolling off the current Lucifer like holy shit it was like a ocean of destruction even though he Sirzechs wasn't flexing his power he could tell the power was just his base form.

Issei was in shock this guy was a terror to behold if he was to get on his bad side but since he didn't hate all devils or any other supernatural beings just the one who mess with his family so he did not want this guy to be on his conscious, oh hell no! he would be crushed like someone crushing a walnut with there boot. and top 10 strongest beings what the hell is that?
Sirzechs: Issei Hyoudou its nice to meet you and thank you for taking care of my son you have my gratitude we were searching the whole underworld looking for him but I must ask why are you opposed to the marriage between my sister and riser phenex?
issei: no problem, your son was a nice kid I can tell he will be someone like if you if he trained hard enough but the reason why I'm oppose to this its because its nonsense it doesn't matter if there trying to repopulate the devils but ruining people lives by making people have an arranged marriage is foolish and my mother also had an arranged marriage but she beat the person in a duel and that's why I'm opposed to it
Sirzechs was happy, he could see that issei was a man with a strong will that will not bend the knee because of someone told him to do something that he more than likely wouldn't do and now he knows what issei is like, Grayfia can also be seen smiling by the courage and heart of issei.
Sirzechs: I appreciate you doing this for my sister you have my thanks issei Hyoudou, you will be fighting a devil named zephydor he is arrogant who looks down on a lot of people so he will most likely insult you for being human, are you ready?
Issei: I'm ready, he better put up or shut up ill show him the power of humanity and why we have so much potential to be great!
Sirzechs approaches issei and puts his hand on his shoulder and teleports to a place that looks very extravagant and sees rias and her peerage, sona and her peerage, riser, and zephydor.
Zephydor: so you must be the human that wants to end this marriage, do you honestly believe you can beat-
Issei grabs the arrogant devil face and throws him to the arena.
Issei: I had enough running your motherfucking mouth already either you put up or shut up.
Zephydor was seething in rage, how dare this human grab him! he will flay this humans bones
Sirzechs: ENOUGH!! Zephydor you will fight this man named issei Hyoudou for the freedom of rias Gremory and riser phenex do you have a problem with this?
DCM(Devil Council members): WHAT?! Lord lucifer this for the benefit of the underworld why should it because of this dumbass human with and hero complex he should be killed right now-
but before he could finish the rest pf his sentence issei activates his conquers haki which covers the whole underworld alerts the other supernatural beings with the killing intent they felt
issei: you shut the hell up you ignorant old prune no ne will remember you if I killed you right now let the adults talk while sit there like a useless speck of dust you are do I make myself clear clown?
The man didn't answer but who is this human where did he come from and he could make an excellent peerage member. Zephydor who was heavily sweating THAT pressure coming from a human how the hell was that possible?
Zephydor: No Lord Lucifer ill show this human who he's dealing with! he answers while still shivering
Sirzechs: issei, are you ready?
Issei: yeah lets do this!
they both teleported to the middle of an arena and activated there magic and rushes towards each other and issei activates his observation haki and easily doges him and zephydor completely misses him he goes on to throw hands but issei just doges him and trips him where zephydor easily recovers and goes in the air to throw a green energy spear and throws it at issei who just bats it away and just looks at him with bored eyes
issei: is that your best? I though you were going to show me who I'm dealing with? or are you just talking at of your ass?
zephydor: you insignificant human I will make you scream out for your mother-
but before he could do that he was cut off by a sword that cuts his cheek he then saw issei with a bow in his hands and some type of drill like sword
Issei pulls back the string
issei: My core Is twisted in Madness CALADBOLG!!
zephydor looked up and saw a big blue spiral of energy zooms straight toward right him and screams in rage and horror.
Issei: ah I missed I was aiming for your head but I haven't shown you anything special yet? you ready to quit?
zephydor who was missing an arm eye dyed red from the blood vessels popped from seething in rage HOW DARE THIS HUMAN MESS HIM UP LIKE THIS AND TALKING SHIT HE WILL PAY FOR THIS?!\
zephydor: KILLKILLKILLKILLKILLKILL!! IM GOING TO KILL YOU DO YOU HEAR ME YOU LITTLE SHIT?!!!
Issei: so you still won't quit, I suppose I should show you my sword that I inherited from. but first ill show you all my world
everybody who was watching this was in shock how can this human mess up a devil like this he should be nothing but paste and he's just playing with at that, and what did he mean by show them his world?
Sirzechs couldn't believe this issei Hyoudou is I prodigy in the making he will definitely see if he can help keep an eye out for people who were opposed to the peace treaty the faction were trying to get done he believe he could do that judging by the amount of talent he has.
Issei then says these words that seemingly make the arena heat up and what where is the blistering heat coming from?
I am the bone of my sword
Steel is my body and fire is my blood
I have forged over a thousand blades
Unknown to death nor known to life
Have withstood pain to forge many weapons
Yet those hands will hold never hold anything
This is my path, My forged world made real
This is my Unlimited Blade Works!!
Flames shot up out of the ground and blinds the audience and as soon as they open there eyes they were teleported to a world not there own blistering heat, blades, spears, axes coming out of the ground.
Everyone: Where the hell are we?
issei: Welcome to my world Unlimited Blade Works, my world and my rules.
everybody was shocked the only person who could make a world was a god could this human be the biblical god reincarnated this was unprecedented
issei: now zephydor its time to end This!!
Issei: I am lead here from a multitude of studies, a heap of blades massed by my grandpa's construction, karmas shall be severed, now may your Fall be Humble!!
zephydor is completely enveloped in fire and is seen knocked out with a big scorching slash mark on his chest
issei: it's over!
Grayfia: Zephydor retires! Issei Hyoudou Wins!
rias runs at issei and envelops him in a hug which knocks him down and he just pats her head and he looks up to give riser and gives him a handshake and his thanks
Sirzechs: congratulations issei on your victory but can I ask what was that sword?
issei: I suppose I should reintroduce my self
issei turns around to let the whole world know who was watching this game
issei: MY NAME IS ISSEI MURAMASA HYOUDOU AND WHAT YOU SAW WAS MY GREAT GRANDPA SWORD TSUMUKARI MURAMASA!!
Devils, angel, hindu faction, Greek faction, hero faction, all went wide eyed
