3rd pov

Issei hurriedly went inside and scream for his parent

Issei's Mom: " Issei, why are shouting? "

Issei's Mom and dad said as he approached Issei

Issei: " A-are you okay? Did someone with a weird mask come in? "

Issei's Mom: " Issei don't be rude to the guest "

Issei: " S-sorry "

Issei's Mom: " Well either way we have better news! Your old friend come to visit! "

Issei: " Huh? Who? "

Irina then appeared

Irina: " Ya~ Issei! Long time no see "

Issei: " Who? "

Issei's Mom: " What!? Did you forget about her? "

Issei's Mom then shows Issei a picture of when Issei is young with another young child playing with him

Issei: " What!? I thought you were a boy!? "

Issei's Mom: " Issei! "

Issei: " Sorry! "

Irina: " It's fine, honestly I was a bit too boyish back then "

Xenovia was looking at Asia really hard

Xenovia: " You wi-"

Y/n: " Alright stop that Xenovia, don't start a ruckus at someone's house " *Sip tea*

Xenovia: " Ugh... I understand, Irina it's time "

Irina: " Oh right! Well it's nice to meet you again Hyoudo-San, and see you later Issei "

Y/n: " The tea was nice thank you may god bless you "

And so the three people leave

Y/n Pov

Y/n: " Well then excuse me I need to go and check on something first, you two can go ahead and do the search "

Irina: " Alright! See you later Y/n-Sama "

And so I went on a few enthusiastic walk

Y/n: " This town is full of strays everywhere... Oh well it seems I need to purify this town first before I can focus on the sword "

And so I start purifying lots of stray devils, stray exorcists, and stray fallen angel

And after that, I visited an old acquaintance

Azazel: " Huh? As I expected that scary aura that just came to the town is from you "

Y/n: " Now now~ I'm not scary why are keep saying that about me "

Azazel: " Kuh! Says the most known Exorcist that only few High ranking being in the three factions known because of what you did years ago but man... "

Y/n: " Fufu~ You're overestimating me, I'm not that good there are other exorcists that are more powerful than me "

Azazel: " Ha! If there really is one bring that person to me, I wanna check the person's ability personally "

Y/n: " Sure~ "

And so I take my phone and make a call

Y/n: " Good evening, Samson, Azazel said he wants to challenge you in a contest of strength "

[ Samson: Wahahaha! Is that so? Then I shall take a flight to Japan tomorrow morning!! ]

Samson then cut off the call

Y/n: " So he said, he will come tomorrow probably "

Azazel: " Are you serious.... "

Y/n: " Yes "

Azazel: " Well shit... "

Y/n: " You will have fun with him "

Azazel: " Hell nah! I don't mean like fight right now! Let me do some prep first! "

Y/n: " Why? He won't fight dirty at all? He's a man who only uses pure strength and honorable fight "

Azazel: " A man that can punch a dragon and send him across two mountains is no normal man! "

Y/n: " Well then see you again later~ I just come to visit, oh I also eat the cookies in the fridge, later~ "

I say and leave

Azazel: " Wait the sec!! "

Y/n: *Humming*

I walk around the town enjoying the nice sky

And also feel some magic being used but it does not seem to be that dangerous kind so that means the main enemy is not out yet

Y/n: " Let's just leave it those two, for now, time to go purifying again~ "

Time skip brought to you with a meme

-------------------------------------------------------------

A few hours have passed

Y/n: " Hmm... Ah... "

Now I felt the ominous magic

Y/n: " Well then I suppose I should check it "

And so I went to check it and found Irina pretty hurt on the ground

Y/n: " Irina you okay? "

Irima: " Yes... I'm sorry Y/n-Sama, I was useless and my sword was stolen... "

Y/n: " No it's fine, that thing up there is not really something you can defeat alone "

I say as I look up

Fallen Angel: " Heh... Another insect came huh "

Y/n: " Oh my~ Insect as I am may I know is it you that hurt her? "

Fallen Ange: " We'll it seem you know some manners "

Y/n: " Well a priest needs to learn manners after all "

And then I know someone is coming from my right to attack me and so I let it be

The sword which is just made from light magic so it does not really affect me as it hit me, it did not wound me

Freed: " What the fuck!!? "

Y/n: " Sorry but a toy like that won't hurt me "

Freed: " Tch! "

Y/n: " Aw~ don't be annoyed "

Freed: " Fuck! You just make it more annoying you blind fuck! "

The other seems to come

Xenovia, and a group of devil

I worry about Irina and it does not seem like they will fight

Y/n: " Hmm alright I leave them to you, I need to heal Irina "

And so I leave

Few hours later

Things escalated

Y/n: ( Oh well... I'm just an observer unless it is really needed I guess I will interfere but I won't need to right? There are Geremory and Sitri here but they seem pretty weak, hmm... )

I thought as I heard the others fighting Cerberus

Hmm...

Y/n: ( The one name Kiba seems pretty interesting and has a nice convenient Sacred Gear )

Hmm...

Y/n: ( There is a really lot of interesting stuff here, a surviving Nekomata, the red dragon, and a vampire with a pretty nice sacred gear too although It seems he is not participating sadly )

Hmm... Well it seems that all the interesting stuff they have right now

Y/n: ( Hmm... It's pretty boring Rias Geremory power doesn't really impress me much, unlike her Brother and Father )

Y/n: ( Sona Sitri is also not that strong either although she has a Peerage with interesting Sacred Gear, and she is pretty smart, but that's all for them... Unlike her sister )

Kokabiel looking pretty confident and arrogant up there revealing a lot of forbidden information such as the death of God

But it does not matter to me for I have already known about it... But this will be problematic

A light lance was then thrown to beside me it seems he has gone impatient, I haven't even done drinking the rare Wine I just bought

-----
3rd Pov

Kokabiel: " Oi! Stop ignoring me! And sleep the whole fight!! "

Y/n: " Hmm... But is there a reason for me to be interested in you other than the fact you want to bomb this place? "

The Y/n who always closes his eyes opens his eyes and show his red colored eyes that seem like shining in the dark night

Y/n: " I suppose I should take care of you seems like the others are too weak after all "

Rias: " Hey! My Peerage is not weak! "

Y/n: " Oh well... Xenovia can I borrow Durandal for a sec? I'll give it back later but if you don't want it's fine it's not like I really need Durandal to defeat a small crow "

Xenovia: " Eh? B-but about G-god is-"

Y/n: " Well it's up to you "

Y/n approach the dead Freed step and walk on top of the body as he picks up the broken Excalibur and does a few swings with it

Y/n: " Hmm... This should be enough "

Kokabiel: " Are you mocking me!? "

Y/n: " Hmm? No, I'm just trying to find the best way to not waste too much energy "

Kokabiel: " Grrr! "

Kokabiel throws lots of Light lance

And Y/n response was to swing the sword with a broken blade while still standing on top of the dead Freed

And in an instant, all the light lance just pop and destroy in mid-air

Y/n: " Hmm... I guess I overdid it? Even if it is broken it is still an Excalibur "

Y/n then throw away the broken Excalibur

Y/n: " Oh right? You said you want to fight the Demon King? Are you sure you wanna fight with that kind of weak attack? You'll die in five no four seconds probably more faster "

Kokabie: " You dare mock me you mongrel! I am stronger than him!! "

Y/n: " Nope~ you're weak "

Kokabiel: " You dare mock me even more! " he shout as he shoot a lot kind of magic

But Y/n dodge them easily, and no dust even touch or dirty his clothes

Y/n notice the magic circle is about to go off so

Y/n: " Let's end this quick, how about I show you, just how strong you need to be to fight the Demon King Lucifer "

Y/n put up one finger

Y/n: " Gather... "

A massive energy the gather on top of his finger in form of a Redish black ball

Kokabiel: " What!? "

Rias: " This feeling... It can't be! "

Y/n: : Now now~ this is not the thing you call Destruction power thingy, what I am doing is merely a copy it does not have the destruction ability but... "

Y/n then release the ball at Kokabiel who was too late to dodge as when the small ball was near Kokabiel it grows larger

And devour everything even the barrier that the Sitri set up can't hold it

Once it start growing smaller and disappear we can see half of the school and the ground was gone and become ashes

And then there is Kokabie who is on the ground missing 4 wings, and his right hand and arm

Y/n approach the shocked Kokabiel and he holds his chin making him look at home in the eyes

His eyes light a faint red color for a few sec and stop, as Y/n let him go

Y/n: " You don't have the thing I need either... Well I leave the rest to you, white dragon emperor or do you want a fight? "

he say as he turn back closing his eyes and walk away

And on the sky there was a white armored

White dragon: " No, not after last time, and yes we will take care of the rest "
