Here in this first chapter, there are a few things that you should understand. This takes place a month or two after the betrayel of Aizen, Ichimaru, and Tosen. At this time, there is a captive shinigami in Las Noches. Her name is Yume Tenshi. She was at the time prior to her capture a member of the Thirteenth Division and ranked as the Lieutenant. On a mission out into the human world, she was captured by the Espada- at this time she doesn't know their names so she isn't sure which one it was. She has made a fateful choice that could very well lead to her doom. This is her struggle and her letter to Soul Society explaining what she has done- can you find the secret?

In a small room in Las Noches, a young shinigami begins to write a letter to her friends, knowing that this might be the last chance she gets to tell them how she felt before her death. It had been too long since she had seen them, and there would be no other chance. Yume knew what she had to do. She had no choice but to join Aizen, or die.

When faced with such a choice, she chose the only sensible option. Betray everything she held dear to stay alive. It had nearly driven her insane once she had made that choice- she had been forced to declare her loyality to Aizen and she couldn't get rid of the feeling that she had become worse than any Hollow.

Not long after that, she had received some interesting information from Ichimaru Gin. Her loyality was to be tested. She had no idea how he would test her, but she knew that it would not be easy. Most likely, she would have to kill someone from her past- someone from Soul Society- without any remorse. If she passed, she would be allowed to go on missions to the human world.

Yume was determined to succeed. This was her chance... this was what she had been waiting for. But a small voice in the back of her mind kept asking her if she could go through with it... For all she knew, it might be a lie, or a trap, but there was something in the former Captain's voice that made her trust him.

Trap or not, she knew that this was the best chance that she would ever get. All she had to do now, was gain Aizen's trust... and she would have to cut out her own heart to do it... Easier said than done.

To my friends who read this...

I know that I may never be coming back. Heh. If this were not such a serious matter, I know I would probably make fun of such a dramatic opening... Sadly... the truth must be revealed.

How is this the truth? Well, let me explain. I was kidnapped by the Espada on my last mission and brought to Hueco Mundo- the home of the Hollows. I am being held in the fortress of Las Noches, which is where Aizen has set up his base. I know that some of you will no longer trust me since I have been gone now for over a month... and especially now that you know where I am. I am indeed Aizen's prisoner...

And it has been far too long since I have seen the outside air. So, I have had plenty of time to think over my actions and my possiblities. There is no chance for me to escape. I have thought of every concievable plan, and even a few that were simply ridiculous, and none of them ever had the chance to even get me out of this small room.

This is what I have come to accept- I am guarded day and night... Though how can one tell the difference when its always night in Hueco Mundo... never mind. I am off topic once again. And there is no escape.

Ever since I have been a prisoner here, my thoughts have been my only company... and I cannot keep myself from thinking things that would have normally apaulled me. Things that would make you hate me. Because of these things, I must tell you all my goodbyes.

Abari, I hope that you will understand when I tell you not to wait much longer. If you don't tell her soon, someone else will. Thank you for being such a good friend. You were always a bit headstrong, but you were still nice enough to understand where to drawn the line.

IZuru, I hope that you can understand that I didn't mean to leave you the way that I did. I really ment to apologize for my actions that day, but I will never have the chance now. You probably would have forgiven me and we would have forgotten about it, but now it shall be my last memory as your friend. I suppose you never really knew it, but you meant so much more to me than I could ever have told you to your face.

Every morning, I still hope to wake up back in my bed in Division 13. Captain Ukitake, I am sorry that I am no longer your Lieutenant. You taught me many things, and despite the decisions that I have made, I will never forget them.

Now, down to the reason that I know you all will probably never forgive me. I have begun to think about Lord Aizen's plans. They are the right choice. The path of justice- as Captain Tosen would have put it. I have decided to join them. I will help them in any way to achieve this goal. This is the way and I understand it now.

Please forgive me. And if that is impossible, forget me.

Yume Tenshi

Yume sighed as soon as she had finished. This was perhaps the most painful moments of her life. The letter would be enough to convince Aizen of her loyality... especially if the letter was to be given to Soul Society. He would know that she would have no way back. That she would be trapped just like everyone else on Aizen's side.
