It was completely out of the blue when it happened. It was a quiet night after a long day and you were on your way home to relax, it should have been the end as to any ordinary day but that wasn't the case. You never expected to be attacked; there laying in wait was an ambush of devils awaiting their prey which you were the unfortunate victim of. The ambush that you stepped into wasn't a random attack though, but instead a specific one.
The devil leading the attack knew that you were affiliated with the Occult Research Club (ORC for short) even though you are a fully blooded human. However, that didn't deter the attack or decrease your value to the Devils; it was the exact opposite really. The fact that you were a full human would make it easier to corrupt you; that was the reason you were the target. If you were to be corrupted then you could be used to destroy the ORC from the inside.
However, the process which was to turn you into a mindless slave to the devils was incomplete. You were saved part way through and it was strange, ironic even that the ones who came to rescue you, the ones who were your guardian angels, were in themselves Devils.
Rias, Akeno, Koneko and Asia arrived to your aid. As a result of their arrivals, all of the hostile devils were eradicated before you could be turned but that didn't mean that you were ok. Albeit incomplete, the transformation process damaged and left you weak. So weak that you soon lost consciousness as your four guardian devils rushed to your side.
When you finally woke up, you were ready to believe that it was all some sort of strange dream. Your eyes opened and you found yourself in your bedroom, your head was pounding but that wasn't an unusual thing for you as you've never been a morning person. Again, your head was pounding and you felt a little bit dazed but other than that everything else was fine and so you went to get up and go about your day as usual. That was the point where you realised that something was wrong.
As you went to sit up a hand on your chest prevented that and forced you to lay back down again. You followed the arm up to its owner and met Rias' gaze as she told you to not be so hasty to move. Akeno, Koneko and Asia were standing next to the daughter of the Gremory house as you asked what happened and everything was explained.
As Rias spoke, memories from the previous night started to flood back. Everything up to the moment that you passed out returned: the panic, the noise and even some twinges of pain came back to you as your hand raised to rub your head which started to ache more violently.
"The amount of energy which both Asia and Koneko had to exert to heal you was exceptional as though the transformation process was incomplete, the damage it caused to you was immense considering you're human" Rias said as she kept her hand on your chest to make sure you didn't try to sit up too quickly. "Though there is an issue" Akeno said which caused you concern and to ask what that was. The four devils before you responded by falling silent for a moment before Rias again explained the details.
"Though you wasn't fully turned, the amount of demonic energy within you is substantial and out of balance" she began before Asia cut in; "had you been fully turned then it wouldn't be a problem, but seeing we interrupted the process before its completion, your body won't be able to withstand the damage even with constant healing" she spoke with concern
It didn't take a genius to understand the severity of this situation but being the hopeless optimist you are, you believed that the four devils before you had some sort of contingency for this. "So what are we going to do about demonic energy?" You asked and Koneko answered that the best option was to drain the imbalance that resided in you; "completing the process after it was brought to a halt would be too dangerous so draining the energy is the only option available" she explained.
Needless to say, you were eager to have the demonic energy removed as dying didn't sound fun. But of course there was another issue and it was that nobody in the room knew of any methods to drain the energy. "We will look into it straight away but for now all you can do is have Asia and Koneko heal your body as we search" Rias said before assuring, promising that you wouldn't die.
Rias closed her hand over yours as she offered a smile (one that was very gentle considering she was a devil herself) as did the other three, which even included Koneko as one of the corners of her lips turned up. The four of them promised that they would save you and that you didn't have to worry. However, you could tell they were just putting on brave faces as the look in their eyes screamed that they didn't know what to do; that was a cause for you to worry more even though they said not to.
For now though, you were told to just remain calm and remain in your home so that when, and Rias was insistent that it was when, they figured out what to do, they would be able to find you easier. That didn't sound too fun but it was the only option on the table at the moment.
Your only option was to wait until everything was resolved.
