Асаґі Міка

Mika Asagi is the unfortunate victim in the series. The daughter of Big Daddy and Maria, Mika grew up knowing nothing of her father's involvement with Millennion. It was only when Millennion came to kill her and her mother that she learned the truth of her past. Before Maria died she told Mika to find an old friend, Brandon Heat. Carrying a case that contained the twin guns Cerberus, Mika sought out Brandon Heat, only to find that he is now the undead killer Beyond the Grave. With his help, Mika may finally avenge her mother, but does she really want to fan the flames of death that surround her? She acts as Grave's caretaker and technician in the sequel to the videogame.

She uses her own blood to sustain her guardian's body, which has left her physically weak and ill, but does so as only her blood is compatible with him.
