Saya

Many years ago, Saya was born as an original vampire along with her twin sister, Diva, whom was named by Saya on the days before the "experiment" weny awry. After an altercation with Diva, whom is now her worst enemy, Saya must kill all chiropterans by spreading some of her own blood on her katana and slicing any chiroptera and chivalier in her way. Saya vows to kill all chiropterans, by slaying Diva (whom controls all chiropterans), and then commiting suicide afterwards.
