Summary: Mizushima Kaoruko wanted nothing more than to stay invisible until her graduation from Twilight High. Unfortunately, fate had other things in store, and she suddenly found herself the enemy of the most powerful boys in her entire school: the Twilight 4, consisting of Kamenaya Riku (the hotheaded leader), Rizuya Roxas (the quiet, mysterious Prince Charming), Sekiguchi Seifer (the somewhat innocent-looking playboy), and Ebiku Sora (the dictionary definition of "don't judge a book by its cover"). What will she do when T4 issues a "red card", a challenge, out to her? The only thing she CAN do: fight back.

KH remake of the HYD franchise, but you don't have to know the series to read this.
