Regina is the yandere to Mana Aida from Doki Doki Pretty Cure.
She is King Jikochuu's daughter. After her first lost against the Precures, she decides to become friends with Mana - for selfish reasons. However, her relationship develops to a true friendship; she eventually goes through a Heel–Face Turn, but not much later she's thoroughly brainwashed by her father. It's later revealed that she's the dark half of Princess Mari-Ange's psyche, with the light half being Aguri.
Regina has long yellow hair that reaches down to her ankles , decorated with a red bow on the top of her head. She wears a dark grey dress decorated with red details and a black jacket. On her evil outfit ,when she is brainwashed by the Selfish King, her bow and details on her outfit are purple. Regina's eyes are normally blue, but when she is brainwashed, her eyes turn red. Her skin and hair even becomes paler once she is brainwashed.
Regina is selfish, vain, and spoiled. She treats everyone else as if they were her servants and hates anything more beautiful than her. If she doesn't get the Selfish Trio to do what she wants, she acts like a child, talking to them as if they were her older siblings and using her father as a threat. She is also playful and tries to haul Mana around and make her play instead of going to classes or being responsible.
At the end of episode 16, she recalls what Mana said about true friends, but she doesn't know what a true friend is. In episode 17, she is controlled by the red royal crystal, in which it makes her eyes turn red, and it gives her more dark powers. Later when her eyes turn blue again, she starts to learn what love is and becomes more caring, but is turned evil again by her father's dark power.
Yandere Traits Edit
She goes to great lengths to make sure that she is Mana's only friend - by getting rid of her other teammates. This backfires hard.
