Astrellia

==Overview==
Astrellia is the main antagonist, and twelfth Hero of TOKU:S4. Using Haouken XrossSaber with the Brave Dragon WonderRide Book, she becomes Kamen Rider Astrellia.
==Appearance==
Astrellia appears as a young woman with long white hair and a white dress, pale skin and red eyes. She has a visible black bra, and black socks. She has golden shackles on her wrists and ankles. On her back is a tattoo of a white wing and a black wing. Her teeth are noticeably sharp, and her tongue is abnormally long and worm like. Strangely, her blood is purple, and she has two sets of organs which can be seen through her skin if the light hits her correctly.
==Personality==
Astrellia is incredibly childish and sadistic. When she gets bored, she reveals a more evil side of herself, showing no care for humanity. Outside of her basic behavior, Astrellia acts alien and strange. She frequently says unusual things and will do uncanny actions. Her personality can shift between the two, and sometimes gets stuck in the middle, making for a uncomfortable and freighting sight.
==History==
Astrellia was born from Grand Father putting a soul into a piece of his body. After incubating for a unknown amount of time, Astrellia was born. Her childhood is unknown. Anything before her appearance is a mystery, outside of her briefly mentioning training.

Astrellia's death was uneventful. After being hit with many strong attacks, she began to get too excited and was tricked into believing death is incredibly painful, which allowed herself to be killed. Upon realization that she's been tricked, she caused the Dimensional Merge to become worse, causing the rest of the Others to appear, along with far more Hero Gear, in hopes of causing a war.
