Prologue: A Promise to Kill, A Resolve to Die
She slowly reached out and with a moment's hesitation, finally touched the back of her companion's hand with hers. "Haji...I need you...to do me a favor..." She couldn't look him in the eyes, she couldn't bear to see the sadness she was about to inflict upon her most trusted Chevalier, she could hardly hold back her tears at the thought of hurting Haji.
Yet this was something she had to ask. This was something only he could do.
With a smile, Haji whispered, his greenish-grey eyes looking lovingly at the girl, who seemed to be no older than sixteen. "Saya, you know that I will do everything that I can to help you get what you need."
Saya bit her bottom lip, to the point where she could barely stand the pain. "I need you to make me a promise..."
"A promise?" He could feel her grip his hand more firmly than before. "Saya...what kind of promise?"
A tear fell, and slid slowly down Saya's cheek, and when she spoke, her voice shook. "That when this is all over, Haji you'll..." Another tear fell, and her body trembled as badly as her voice had, the silent sobs of anguish tortured her. When she felt she couldn't take any more of it, she did the first thing that came to her mind and cried out what it was that she needed Haji to promise to. "When this is all over, I need you to kill me, Haji!"
Every breath that Haji held onto escaped at that moment, only he wasn't allowed to die...he couldn't die from this kind of wound. "Kill you? Wh-what do you mean, Saya?"
Her shoulders slumped forward in defeat, she'd hurt the one person she'd vowed to never hurt, at least no more than the damage she'd already inflicted on him. "Haji...you and I both know what I am...and I could never co-exist with humans...not after learning that I'm..." She looked down at the hand that was still using to clutch onto Haji's. "That's why...after I defeat Diva...after I complete this mission that I'm setting out to do...I want you to kill me with your own hands...Haji, you're the only one who can do this for me..."
"But Saya...I-"
"Promise me, Haji!"
With a sigh, he quietly whispered, "I promise that when this is all over, I will kill you, if that is still your wish at that time..."
Saya nodded, and released Haji's hand, "Thank you."
