Maria Kurose

She is the first crush of Ryuuto Kashima and the fraternal twin sister of Runa Shirakawa. Maria comes across as a sweet girl, but deep down she is cold and underhanded where she rejected Ryuuto Kashima when she confessed. But then, when she found out that he was dating her twin sister Runa Shirakawa, Maria resorted to spreading rumors about Runa to try and ruin her image just to ensure that she is number one. She is also childish in that she will cry when she is called out to try and look innocent.
