Issei Pov

Issei: " So... What's next Prez "

Rias: " We'll since Riser is the only one left... Now it's either we all attack him or would you like to do a one-on-one to exhaust him? "

Akeno: " Fufufu~ so we are going to gangbang him hmm~ "

Issei: " Please don't say it like that... "

Akeno: " Ufufu~ "

Koneko: " As long as I can punch him in the face I'm okay with any plan "

Kiba: " I'm fine with any plan to "

Rias: " We'll then I guess we'll be gangbanging him, of course with extra steps~ "

Issei: " Ugh... The wording just sounds wrong please stop... " Issei looks disgusted and troubled

Rias: " Fufu~ "

Issei: " Ugh... "

Meanwhile with the watchers Y/n

Asia: " Hmmm...? What do they mean by gangbanging him? "

Y/n: " Hmm... Ah! I think they mean they all gonna ambush him from the back I think? "

Asia: " Oooh! Is that what it means? But Issei-San looked pained hearing those words "

Y/n: " Well I don't know what else it means, I mean I only know a bit cause I used to play games with my sister and sometimes she would say 'Alright! Y/n were gonna gangbang his ass!' and so we sneak around and attack the enemy from the back the same time "

Asia: " Oooh! Your Sister sounds like a fun person to be around "

Y/n: " Yeah... She was fun but pretty lazy thought "

And on the sideline

Sona: " Ugh... Can someone give them some real context of what that word means... "

Tsubaki: *Sigh*

The other members just laugh worriedly and are impressed by the two pure beings...

Back with Issei

And so they went and met Riser the falling bird

Issei went in to the room where Riser is alone

Issei: " Alright f*ckface! I'm gonna defeat you! "

Riser: " Ha! What is this puny devil speaking about, like hell you can beat the great Riser! "

Issei: " Of course I can! Oraa! "

Issei then went and tried to punch Riser, as the boosted gear boosted Issei's strength

Riser catch Isseu punch with one hand

Riser: " Ha! Is that a-guhuk! "

Koneko who burst through the wall punched Riser right in the face sending him flying out of the room to the outside

Koneko: " Yosh... That felt better,"

Issei: " Nice punch! " he said and gave a thumb-up

Koneko: " Right, now let's keep it going "

They both head out of the room through the hole that made by Riser punched till flying out

On the outside, we can see Riser having trouble regenerating his left arm that was cut by Kiba

Riser: " What the f*ck did you do! "

Kiba: " I just simply slow down your regenerating ability that's all~ "

Issei: " Huh!? Since when do you have that!? "

Kiba holds the sword with an odd color in front of his face

Kiba: " We'll I suppose... I got a bit of weight off my shoulders I guess... And that helped me to have a more better mindset "

Flashback to a few days before during the training session

We can see Kiba and Y/n were having a sword fight using a wooden sword

And Kiba was down on the ground with a lot of bruises

Y/n: " Um... Can I ask a question? "

Kiba: " What is it? " he said with his usual polite tone

Y/n: " Why... Do you hate swords? "

Kiba: " Huh? I don't understand what you're talking about "

Y/n: " Well... How can I say this, your way of using a sword is rash, painful, and just sad... It feels like you do not want to have anything to do with a sword or even hold it," he said in a sad and sympathetic tone

Kiba: " Tch... Well you're not wrong " Kiba said honestly and not happy

Y/n: " I see... I guess I know how that felt a bit... I also hate swords... "

Kiba: " Tch! Don't just say you understand it! you don't understand anything! "

Y/n: " I'm not saying I understand your pain I just know how it felt although our reason may be different "

Kiba: " No you don't! My reasons are nothing you can imagine! I hated the sword because it took everything from me! They all died! Because of some crazy sword project! And I escaped but everyone died! It should have been me! I should have died with them! "

Y/n: " And that's why I'm saying! I know how it felt! " he shouted

Which surprised Kiba who heard Y/n shout for the first time in a voice that was just painful like it was about to cry

Y/n: " Look at this... "

Dark orbs gather on Y/n's palm as they form a sword

Y/n: " This sword killed my friend, family, and myself... And yet I wield this very cursed sword! "

Kiba: " ... "

Y/n: " I killed them all! I did it by my own hands I wield this sword and killed them all! Just to strengthen this f*king cursed sword! I need to kill my friends and family one by one with my own hands... The sword was meant to be hope to defeat the enemy... They all die... Leaving me alone... "

Kiba: " ... So... Did you defeat that enemy... "

Y/n: " Yeah... I did just as I promised... But in the end, they still died because of me and they have always been cursing me... Every day even now... I see them and they remind me of my sin... My choice... So you know... Every day I always wanted to die and just go meet them and beg for forgiveness... I'm sure you also wanted to do that after you done your revenge... "

Kiba: " Yeah... "

Y/n: " But... You know what, I'm still alive because I make a promise to them to make sure protect the people... Which is probably an invalid promise by now... But what about you? Did you make any promises to your friends and family Kiba? "

Kiba: " ... Yeah... They want me to escape and live... "

Y/n: " Then... Once you have done your revenge you need to Live to the fullest just like you promised with them... And think of that the sword ability you have right now is like a gift left by your family and friends to help your vengeance and live your life to the fullest "

Kiba: " ... "

They both then went silent as they looked at the moon in the sky with tears streaming down their face

_______________________________________

A/n: So I decided to make the reason why Kiba Super Op sacred gear was never really used properly in the anime was that Kiba hated the sword and even though he indeed wanted to use his ability for vengeance he didn't like to think about a sword even a bit

That is why some of Kiba's sword was pretty much normal sword with some having deformed form, because he didn't like the idea of imagining a sword
