Y/n was sitting in class when he saw Issei and Asia walking to him

Issei : "Y/n Rias wants to speak to you"

Y/n smiled and followed them as they arrived they entered to see Rias and Sona with their peerages, along with Sirzechs, Serafall, Michael and Azazel as Y/n entered everyone looked at him

Y/n : "what do you idiots want"

Sirzechs : "hello Y/n my name is"

Y/n : "no one cares what do you want"

this annoyed them but they continued

Azazel : "we would like to know who you are"

Y/n : "whats it to you"

Sona : "Y/n stop being rude"

Y/n : "or what you know I heard about how your Faction lost family shame you weren't one of them"

this annoyed they all again

Xenovia : "Y/n stop"

Y/n : "oh Xenovia, who is being a devil after begging that red haird bitch to let you join them after finding out that God died"

this surprised them

Irina : "you know that"

Y/n : "yeah I do what kind of idiot dies by his on creation, if you ask me I'm glad his dead"

this angered Michael and Irina as all of them were pissed off Sirzechs talked to Rias and her peerage in his mind, but what they didn't know was Y/n was listening as well

Sirzechs(mind) : "Rias we must dispose of Y/n I'm sorry to say but we can not let him live, he knows to much"

Rias(mind) : "I understand Issei will you do it"

Issei(mind) : "yes anything to protect my friends"

al the girls smiled at Issei while Y/n looked like he was gonna puke

Y/n(mind) : "I'm going to enjoy this"

Potusdod(mind) : "you and me both"

Y/n looked to see Issei in his balance breaker form Issei charged at Y/n, when he did Y/n just smirked

Y/n : "and.... bingo"

Everyone's eyes widen as they saw Y/n's hand go right throw Issei's chest, Y/n rip his hand back out and was holding a red orb in his hand he looked to see Issei's armour fall off and him hit the ground with a large hole in his chest

Rias(Crying) : "ISSEI!!!!"

Rias and her peerage ran to Issei crying and worried about him, the leaders looked in shocked and Y/n just smiled

Y/n : "well its been fun"

Y/n then placed the red orb on his chest and it slowly went in

Serafall : "what did you do"

Y/n : "I took his gear that's what I did"

Azazel : "are you crazy he could die"

Y/n : "I now that but I just dont give a rats ass if he does die"

Rias : "you"

Y/n looked at the group who was pissed at Y/n

Rias : "YOU WILL PAY FOR HIS DEATH"

just then everyone raised their power which Y/n found cute Y/n smirked before letting his power out

everyone turned from angry to scared in seconds

Y/n : "whats the matter come on make me pay..I Dare you"

Y/n looked at the factions leaders who looked shocked

Sirzechs(scared) : "t..this power it cant be"

Y/n : "EMERALD DRAGON GUARDIAN BALANCE BREAKER"

Everyone looked scared as they saw Y/n standing there in his new armour

Everyone backed up scared and Y/n headed to Issei who was scared and crying, he picked him up by the head and made Issei look at him

Issei(crying) : "Y/n please"

Y/n : "you were always pathetic now look at you, you're like a little girl"

Y/n grabbed Issei by the neck and looked at the rest of them

Y/n : "let this be a warning to all of you if anyone steps out of line with me"

Y/n then snapped Issei's neck and dropped his body

Y/n : "I will kill every last one of you"

Y/n left leaving a group of crying Devils and scared leaders but Y/n didn't care
