Fan Casting MyCast: Bakumatsu: Gaiden: the Two Moons

Saya survived after half of her head got blown off by a gunshot from Fūma. However, her left eye was severely damaged due to being shot with a silver bullet (one of the main weaknesses of a Rasetsu), so she bandaged her left eye for the rest of the series. She decided took an indefinite rest and hide from public until it's the right time, with her father and Hachiro covering for her by confirming her death. Meanwhile, the man in black returns to cause chaos again, but this time, he brings a surprise. In the form of Saya's twin sister named after her late mother "Maya". Saya's childhood memories about her mother resurfaced as she and her father were faced with the harsh truth that Maya was actually Saya's unborn twin sister who died inside their mother's womb and reborn through cloning by the man in black. Turns out that Maya is only the beginning of a grand plan of turning all populations of Edo into a more dangerous breed of Rasetsu created from Maya's blood. Saya is struck with doubt and guilt whether or not she should kill Maya to end all of this or give in to her murderous self and become the demon that she always feared she would become.
