Hello there, and welcome to what is my first attempt at a Tokyo Ghoul fanfiction. Before we get into the story, I would like to say that this is unbeta'd, edited by myself, so please inform me if you spot any errors. Secondly, as for the plot and direction of this fic, I only have a very loose idea of where I want to go with it, and it's a very experimental idea to begin with. Meaning, I'm not sure how often I'll be updating this, because right now I'm uncertain as to whether I want it to be a long-term project or just something I throw out there just to see what happens.

As of right now, I have also not read much of the manga, but I plan to rectify this as soon as possible because I would like to follow the manga's story, at least to an extent, should I continue this.

I do not own Tokyo Ghoul, in any way, shape, or form. This plot and these OCs are definitely mine, however.

PROLOGUE/INTRODUCTORY

She never intended for this to happen. This wasn't what she wanted, not by a long shot. Her sister was the most important person in her life, the only one in her small world who was truly capable of understanding her. The bond between them was something that could never be broken – at least, that's what Yuzumi had thought for the meager seventeen years that she had been alive.

She had always figured, had always believed that she would die first, and she was fine with that as long as she had her elder twin sister by her side until that fateful day. Rio, her sister, she was tough. There was no doubt in Yuzumi's mind that she would be able to keep on living her life even after she was gone. After all, despite how much they cared for each other, there was no denying the fact that Yuzumi was the weaker of the two, the one who always needed protecting. It was sad to lose a loved one, but Rio would really be better off without having to worry day and night about her sickly younger sister.

Yuzumi was ready to die. The moment her legs stopped working correctly, the moment she lost the ability to stand on her own two feet, she knew she was more than ready. If she had been a burden before, then what was she after? Spending her entire life like that, crippled before eighteen? If it wasn't for the fact that her body was already deteriorating, dying faster than any healthy person should, she would have put the gun to her temple and pulled the trigger herself.

She almost did once, admittedly. When the struggle of trying to live in her own frail body became too much to take, and she was at her wits end, her sister had found her with a knife leveled at her wrist, ready to end it all. Rio had been understandably furious, and Yuzumi wouldn't ever forget the way she had slapped the blade from her shaking hands, taking her by her thin shoulders and shaking her until she came back to her senses.

After that Yuzumi didn't ever try to take her own life again. The look in Rio's eyes, the fear and desperation that they had held had been more than enough to set her straight. She didn't ever want to see someone who was as strong, dependable, admirable and important as her sister looking like that again.

However, if Yuzumi had known about the decision that Rio would come to make in the future, she probably would have taken that knife to her wrist again and again, as many times as it took until she stopped breathing.

Rio was capable of living without Yuzumi. She had shown she could many times over. As cold as it sounded, she didn't need a crippled little sister to weigh her down.

Yuzumi, however, knew she couldn't survive without Rio. She knew little about the world, she had depended on her sister her entire life because she had no other option – she wasn't anywhere near ready to embark on a new life without that guidance.

The bond between sisters was a strong one. The bond between twins was even stronger. Throw in a weak and helpless younger twin into the mix, and there's nothing that can sever that link, aside from death.

…

Rio was the only person in Yuzumi's life who could raise her spirits, the only person she trusted.

Rio was the one person who could not be replaced.

Rio was everything Yuzumi wanted to be.

Rio was dead.

And Yuzumi was the reason why.
