A/N: Sorry for the incredibly short prologue! I will work harder on the upcoming chapters. Thanks to those whom have read the prologue, and a big thank you to Gianti- Faith and Yoshizawa Ayumu who reviewed my prologue! I only own my OC and ideas. Please enjoy!

Mizuki slows down when she spots a young girl dressed in men's clothing. Mizuki decides to follow her as she aimlessly wanders around on the street. Suddenly the girl bumps into three drunk ronin, ' What an idiot.', thought Mizuki, preparing to help her, but then the girl ran off. Sighing, Mizuki followed the girl in the shadows, trying to get an opportunity to stop the ronin. When the girl hid in an alleyway, Mizuki got the perfect chance at getting rid of the rouge samurai. Before she could attack, Mizuki heard a hideous laughing sound and saw two white haired, red eyed men in familiar blue haoris. She instantly realized that they were the haoris of the Shinsengumi.

Suddenly the rasetsu began attacking the ronin. Since they were distracted, she decided to kill the strange men because they were also a threat to the girl. Mizuki instantly attacked, slashing then stabbing her opponents with her twin katanas, unaware of the watchful eyes of three important members of the Shinsengumi. As soon as the last rasetsu died, Mizuki got rid of the blood staining her katanas before sheathing them. Mizuki glanced at the girl to make sure that she was safe, noticing that the girl had fainted. She turned to face the vice- commander, and the first and third division captains, before bowing and disappearing into the shadows. When Mizuki disappeared, Hijikata noticed a letter addressed to Yamazaki floating to the ground by his feet. Puzzled by the letter, he pockets it, making a mental note to give it to Yamazaki later. Hijikata goes over to join Okita and Saito, whom were standing in front of a young girl disguised as a boy.

" What should we do with the bodies?". Okita asked Hijikata, unaware that Mizuki was watching them.

Hijikata told Okita and Saito to get rid of the haoris and take the girl back to headquarters. As Hijikata thought about why Mizuki had protected the girl, Saito gathered the haoris as Okita protested against bring her back. Eventually, Okita picked up the girl, while complaining. The three Shinsengumi members started heading back to headquarters, having completed their task. Mizuki started to follow them, when Saito suddenly turned his head and looked in her direction. Mizuki panicked and quickly hid, scolding herself for underestimating him, he had been more perceptive than she had thought. When Mizuki looked again, they had vanished from sight.

A/N: That's the end of chapter one, I hope you enjoyed it! Please note that this story is written in no one's point of view, so they don't know each other's names, yet. This chapter may be short, but I promise that the upcoming chapters will be longer! Thank you for reading and please review so I can change my mistakes! I will try to post a new chapter every week.
