Onibara is the main villain of Pretty Cure Monster Mania. She is the leader of Black Roses and a demon from rather mysterious origins with an obsession with roses.
Not wanting to be confined to a single world, her goal is to open the gate from Halloween Hills and Seinarushima to create an eternal Halloween.
A sly and devious demon with a huge love for roses, to the point of obsession. Despite being very manipulative and sadistic, Onibara has a calm disposition which can make a sudden turn to aggression in a mere second. She loves making humans miserable just for fun and desperately wants to collect Fear from people for a somewhat secretive goal.
Despite her manipulative nature, she is quite charismatic and fair towards her followers, or at least tries to be. Onibara is definitely more more cruel towards humans.
- Onibara - Can read be as "Demon Rose".
