Rice Shower

The one called "Record-Breaking Black Assassin." Regardless of her own intentions, she's become a villain due to the unfortunate circumstances of her childhood, outside her control. Despite that, her personality is honest and pure. Though destiny has played a cruel joke on her, she's a strong, beautiful girl who fights with all her strength. She's not good at talking to guys, unless they're a trainer, who she would think of as a brother.
