(Anime Crossover) Listen, Loneliness Is Singing

Hush. Be quiet. Listen, loneliness is singing. Monarch once thought that dying at A Xue's hands would mean she had completed the mission her leader gave her. But she never imagined that this wasn't the end, but the beginning of another cycle. She would go on living in this world as the pureblood princess, Yuuki Kuran. So many people disturbed her once-peaceful life from the moment she became Yuuki Kuran... "Hey, A Xue, was I wrong from the moment I died at your hands?" This is simply the story of a girl wandering through different worlds. PS: The heroine is a transmigrated assassin, and a thoroughly wicked one at that. If this is already a red flag for you, please quietly look to the top-right corner and leave... Other stories will be better than mine. Things to know before reading: - The heroine isn't all-powerful. This pureblood Yuuki Kuran's body can't use its powers at all. Against boss-level characters, she can only be bullied, and even smaller bosses could very well overpower her. - There is an 80 percent chance of a 1v1 ending. The rest will most likely be alternate endings, though there may be no CP. - Characters may be out of character, so beware. Honestly, I'm the one quietly making them all act out of character. - The heroine's personality may be a deal-breaker: she's cold to an extreme. I'll try not to make her act out of character, but you absolutely won't see her being gentle. (Except with A Xue, of course, but they've already gone their separate ways.) A note from the author: I'm back... Updates are slow as a turtle, and I can't help that, so please forgive me! Of course... please don't rush me for updates. If you do, I'll go crazy. General route: Vampire Knight -> Katekyo Hitman Reborn! -> (undecided)... Worlds she will probably visit (subject to change): Vampire Knight, Katekyo Hitman Reborn!, Shaman King, Yu Yu Hakusho, Hunter x Hunter, D.Gray-man, Naruto, Hikaru no Go, D.N.Angel, Shonen Onmyoji, and Fullmetal Alchemist. ---->>>> My profile page.
