Y/n was sitting in class when he saw Issei kept looking at him, as the final bell rang ending school Y/n was packing his things when Issei walked up to him

Issei : "hey Y/n"

Y/n :"look if you want to fight lets do it later I have places to be"

Issei : "no that's not why I'm here"

Y/n : "then tell me already why your here"

Issei : "Rias Gremory sent me to come and take you to meet here"

Y/n knew the idiot wasn't going to take no for an answer

Y/n : "you got 10 minuets"

Timeskip

Y/n was sitting across from Rias and her peerage

Y/n : "I'm here what do you want"

just then Rias smirked

Rias : "you see Y/n I brought you here because I know you who really are...Hell Walker"

When she said this Koneko looked shocked while Y/n just didn't care

Y/n : "so"

Rias : "I have a deal for you"

Y/n : "whats that"

Rias : "I want you to join my peerage and when I go public with your real name you wont have to deal with the devils that what you dead"

as Rias and her peerage had a smirk on them Koneko was shocked Rias would use force to get what she wanted, after a few seconds Y/n burst into a laughing fit

Y/n : "that's a good one"

Rias : "I wasn't joking"

Y/n : "you know Gremory you remind me of your father"

Rias : "oh do I"

Y/n : "yeah...he was also a little bitch"

this annoy Rias

Rias : "what did you say"

Y/n : "I still remember that day, he along with the other devils bowed at our feet like the cowards the devils really are"

this annoyed all of them apart from Koneko

Y/n : "oh whats the matter did I upset little princess what are you going to do get your weak ass brother to get me, or get the rest of the devil race which I've seen and all honesty, a blind human with 1 arm and his legs tied would put up a better fight that the weak ass devils"

Rias : "Enough I will not let you disrespect my family's name anymore I challenge you to a rating game and if I win you become my new rook"

Y/n : "fine but if I win"

Koneko : "if you win I'll leave Rias"

Y/n smiled at her while the devils looked shocked

Y/n : "well that's that see then you dumb asses"

Timeskip(in the underworld)

Zeoticus : "YOUR DOING WHAT?!?!?"

Rias was her peerage(apart from Koneko)was sitting on a couch and standing in front of her was her Father Zeoticus Gremory, her Mother Venelana Gremory, her Brother Sirzechs Lucifer and her Sister In Law Grayfia Lucifuge and they were not happy

Rais : "I challenged 1 of the hell walkers to a rating game"

Venelana : "which 1 was it"

Rias : "The Red Reaper"

all of them paled

Sirzechs : "this has to be a nightmare"

Venelana : "what possessed you to challenge 1 of the beings that brought the supernatural world to its knees"

Rias : "I wanted him to join my peerage but he said the devils bowed to the hell walkers so I defended the devils honour and challenged him"

Zeoticus : "Rais what he said was true all the factions begged them to stop we lost so many devils trying to fight them but we didn't even slow them down"

Rias : "I found out his real name we could blackmail him into joining us"

Sirzechs : "Rias think about it even if we know his name do you think it would make a difference, everyone in the underworld fears them not even Ophis the Dragon God of infinity wants to fight them"

Rias hung her head down

Zeoticus : "the least we could do is ask him not to kill anyone but even then he might not listen, you have over stepped the line Rias we thought you would be responsible enough to learn that picking a fight with the hell walkers was not a good idea"

Venelana : "Rias as of this moment on Sona will be in control of Kouh until you can prove to us that you have grown up"

Rias : "I understand"

Sirzechs : "you better start training"

While rias and her peerage trained hard Y/n was making a choose that would change the world forever....

Y/n : "Banana or Cucumber, Banana or Cucumber, Cucumber or Banana"

Koneko : "just pick one"

Y/n : "you can't rush such a important decision like this kitten"

Koneko : "are you sure about taking on Rias I mean I know you can win but she is going to try something"

Y/n : "don't worry kitten I already have a plan"

Koneko : "you do?"

Y/n : "yup any second now"

10 Seconds Later

A portal opened up and Koneko's eyes widen while Y/n just smiled

Y/n : "hello Dad

(I know he doesn't talk but In this he will)

Doom : "hello Y/n I see you found Shirone"

Koneko : "hello again doom"

Doom : "so why did you call me here Y/N"

Y/n told his dad everything and he agreed to fight beside Y/n but then he smirked behind his helmet 

Doom : "so are you to living together now"

Koneko : "w..we're dating"

Doom : "Y/n..."

Y/n : "yeah yeah"

Y/n hands Doom Guy a 50

Y/n : "hope your happy Kitten"

Koneko just giggles

Koneko : "very"

Y/n : "your evil"

Doom guy laughed and then he remember something 

Doom guy : "Shirone I have something for you"

Doom guy handed her a box and she left when she came back she had Armor on 

(I know its halo Armor but in this it will be a Praetor Suit)

Koneko : "I..its a bit revealing"

Doom : "I'm sorry about that the guy would made it was a bit of a pervert"

Y/n : "tell him I own him a beer"

Koneko blushed while Doom guy hit Y/n

Y/n : "what was that for"

Doom : "for being yourself"

Y/n : "well Koneko looks great in a hot kind of way"

thanks to the helmet no one could see Koneko blushing like mad

Koneko : "w..well thank you for the Armor"

Doom : "no problem its the same as Y/n's just looks different"

Doom guy then left to take a shower will Koneko turned to Y/n

Koneko : "do you really think I look good in this"

Y/n : "want me to prove it"

Y/n walked to Koneko and took her helmet off and kissed her 

Y/n : "you looked amazing"

Koneko : "thank you Y/n"

Y/n : "now when he comes down we can talk about what to do but until then...."

Y/n : "Banana or Cucumber"

Koneko : "I have a better Idea"

Koneko grabbed Y/n's shirt and kissed him after they were kissing for a bit Doom guy came down and the started planning an attack...and by attack I mean they agreed to run in head first and punch anything that attacks them....
