V2 ch 2

Ok before we get into this listen to a song called transformation from the world ends with you it's a great song and during part of this chapter I listened to it because of well you'll see and the title of course but let's get into it
__________________________________
Y/n: "I'm sorry you want to make a a WHAT?!"
Ddraig: "Hear me out it would make you stronger while also giving you something else to pour you power into, allowing your pieces to try and catch up."
Issei: "Is that even possible?"
Ddraig: "Theoretically although I've never met someone who could handle the transformation as it changes every aspect of your being, you'd be made of energy, have a new kind of Aura and your physical and magical prowess would grow beyond your imagination, but you'd be giving up your humanity-"
Y/n: "Fuck humanity if you think I can survive being turned then I'm all in."
Ddraig: "I thought you wanted to keep your humanity and that was the reason you asked Rias to stay human."
Y/n: "That was for being a devil and that's lame but this, this is on a whole new level."
Issei: "Hey I'm a devil you know."
Y/n: "Shhh the adults are talking."
Issei: "You did not ju-"
Y/n: "Shhh, now Ddraig how do we do this and what do this and how long will it take?"
Ddraig: "It would take at least 24 hours."
Y/n: "Ok Issei tell everyone I'm going to be MIA for a while as I'm doing something Sirzech told me to. Alright I've got a pen and paper to write the process down, let's get started."

Time skip
Issei's pov
I walk into the orc building with Rias, Koneko, Mittelt, and Asia all looking worried and or angry.
Issei: "H-hey before you do anything to me I've got a message from Y/- Gahh"
Koneko: "What did you do perv."
Issei: "I didn't do anything he's on a personal mission from Sirzech. Please don't hurt me."
Koneko let's Issei go as he take a few steps back and clears his throat.
Issei: "He told me to tell all of you he got a last minute request from Sirzech and that he'd be gon for at least a day."
Rias: "Then I'll talk to my brother so find out where he is at the very least."
Issei: "NO DON'T... Uhh he said not to ask because he wanted to bring you all something back and if you knew where he was it might spoil the surprise, yeah that what he said."
Mittelt: "Of course he'd bring me something back he clearly loves me."
Koneko: "No he loves me."
Asia: "I won't lose to you two he loves me."
Rias: "You three need to know your place he's mine."
Issei: "I need to change the subject before something bad happens... Wait where's Kiba?"
Rias: "He said he need to handle somethings after we told him about what happened yesterday."
Issei: "Oh and when are we going to be meeting with Irina and the other girl from yesterday."
Rias: "That will be after school today."

Meanwhile
Y/n pov
You are in the woods just outside of Kouh and you're currently drawling a magic circle and preparing the process for your transformation before you sneeze.
Y/n: "I feel like I'm being talked about, then again I did leave everyone with out notice and told Issei to give them a message. HAHAHA he's so dead I doubt he'd even be able to finish a sentence before being threatened about what happened to me... on that note I'm so dead when I get back... oh I'm done ok so time for the spell." You begin to speak the incantation and when you finish nothing happens.
Y/n: "Really? Nothing, did I mess up-"
Right when you were about to start over you feel like every done in your body breaks before coming back together and every atom of your body rips itself apart and comes back together.
Y/n: "Ahh this is the worst pain I've every felt it feels like my very soul be changing its shape."
This process continues for what feels like and eternity before it finally ends but before you can even comprehend what all has happened or your surroundings or even what you look like you pass out from the pain of the experience.

Back to Issei
Ddraig: "We never properly thought him the incantation in its native language did we?"
Issei: "I'm in class and what are you talking about?"
Ddraig: "That definitely not good his transformation may end up being slightly different that what we hoped."
Issei: "Ddraig what does that mean?"
Ddraig: "Best case scenario he turns into what he wants worst case he'll be a nekomata or hell hound maybe even one of the three biblical races."
Issei: "And you're just remembering this!"
Ddraig: "Don't worry he can still do the spell again but he'd probably end up keeping some aspects of whatever he turns into after this."
Issei: "So there's a chance we can convince him not to kill us?"
Ddraig: "Yes"
