Issei was staring at his opponent right across from him and could feel every ounce of power you were producing and more kept coming, but he still had to try and defeat you he charged and swung at you the hardest he could and you let the hit happen but you didn't go anywhere there wasn't even a scratch on you.
Issei: 'Oh crap basket-'
His though was cut off by you punching him in his gut making him fly the other way
Issei: Agh!
Rias: Issei!
Issei landed and you were instantly in his face. He tried to throw his guard up but you punched him quicker then grabbed his head and kneed him in face cracking his armor
Issei: 'Shit!'
He grabbed your arm and flipped you slamming you into the ground making the ground shake. You recovered quickly and did a spin hook kick making it land on his ribs.
Issei: 'There's a lot of power behind his kicks! It's impossible to defend my self!!'
He in the air when he refocused and (Y/n) grabbed his legs and slammed him the ground over and over again
(Like This)
Issei: AHHH!!!!
You held his foot and spun him slamming his hard making a bigger caterer and threw him away
(Y/n): Weakling!!
Issei landed with bruises and cuts all over his body and blood ran down his head with pieces of his armor messing
Issei: *Couldn't breathe right* D-Damn it... 'Ddraig I need more power'
Issei then thought of something and stood up slowly
Issei: You know... you're really weak..
(Y/n): Says the one who's almost beaten into a bloody pulp
Issei: How about you beat me with you're own natural power and skill huh?! You used that borrowed power to make yourself stronger. It's not your own!
(Y/n): Oh come on. You really think I would fall for such an obvious taunt?
Issei: Well yeah, if you had any pride in yourself
(Y/n): pfft heh, okay then.
You're armor disappeared and your eyes were the same color and you smirked
(Y/n): Get ready for the fight of your life Issei
Issei charged throwing multiple punches that you were easy to dodge and you grabbed the hand his sacred gear was on you squeezed it. Then it started to burn
Issei: Ah let go!
He punched you with his free hand making you let go then he held his arm in pain and say burn marks
Issei: The hell?
You placed your hand on a tree and blue fire started to appear and your eyes turned Blue
Issei: Why are you doing this why? What do you gain from this?!
(Y/n): You dying! You took everything away from me! Everything I ever loved!
You jumped and got near his face and his eyes widened how quick you got there
(Y/n): BURN!
Issei came out of it barely alright his armor was gone and most of his clothes were torn.
Issei: *Huff* *Puff*
You grabbed what was left of his shirt and beat the living shit out of him
Issei: ....
Ace: Boss he's has enough..
You snapped your head and looked at Ace and dropped Issei
Ace: You said it yourself you won't kill them now.
Rias flew with Akeno and fell in front of Issei
Akeno: (Y/n) p-please don't go...
(Y/n): ...You dont have the right to call me by my name anymore..
Akeno: (Y/n) you have to listen to me please.. my attention was never to hurt you we jus-
(Y/n): Liars! You're a liar! A cheater, a whore! All of you! You just wanted Issei for what?! What does he have that I don't! Tell me!
Rias: (Y-Y/n) c-calm down!
Ace: Boss?
(Y/n): You dare tell me what to do after everything you did?!
(Y/n)'s eyes changed a different color and had a weird pattern on it
(Y/n): Rias! You're no different! I laid down my life for you! I did everything I could to make you and the rest happy and you wanted a pervert!
His hands were balled up Into a fist and blood started to drop from his hands.
Rias: I... We now we made some bad decisions (Y/n) listen there's more at stake here tha-
(Y/n): SHUT UP!!!!!!!!!!!!!!!!!!!!
His voice scared them. A gust of wind came out of nowhere and a strange aura surrounded (Y/n) and he clenched his head and screamed in pain
(Y/n): Ahh-AHHHHHHHHH!!!
The pair of eyes shot at Rias and Akeno scaring them of what you had inside you and what you had become. They got knocked out because of how scared they were.
Ace used a little bit of his powers to calm down the rage and it showed you knocked out on the ground.
Ace: *Sigh* it's okay Boss I got you.
Ace picked (Y/n) up and threw him over his shoulder and walked away with a knocked out (Y/n)
-In Akeno's Head-
-In her nightmare-
She was wondering around on a beach and she saw you
Akeno: (Y/n)!!!
She ran and jumped to hug you but the scene changed and she was at the clubhouse
Akeno: The hell? (Y/n)?! Where are you?!
She did wondered inside the clubhouse to see herself and the rest of the girls sleep with Issei then a door opened to see (Y/n) alone and sad because no one was with him.
Akeno: (Y-Y/n) no...
Tears started to form and she tried to walk closer but a force pushed her back
(Y/n): You never loved me...
Akeno: No that's not true...I'm sorry! (Y/n)!
(Y/n): Akeno...I hate you...
Those words broke her and she saw you hold a sword in your hand
Akeno: (Y/n) No! Please (Y/n)!!
(Y/n) didn't say anything but his eyes looked emotionless and he ran at her and went to stab her, before the contact was made she woke up and she was in her room with sweat running down her face and In bed with her was Rias and she got up and walked out of the room
Akeno: 'I need to get to (Y/n) no matter what I have to do. No matter what it takes..'
