One of the main female characters. Kurusu is an alien and came from a planet where her tribe has the power to use the skills and powers shown by the clothes she is wearing ( mostly uniforms ), and so she is known to always wear cosplay. She apparently loves Kazuya at the start, since she confessed her identity to him, but their conversation was interrupted by guardian heart. She also hates the guardian heart for interrupting her from confessing to Kazuya. She also lives with Kazuya.    &quot;Taken from Wikipedia&quot; 

Maya, Kurusu, and Chelsea hit it off really well when trying to get revenge on Guardian Hearts for making them suffer. Maya and company thought that Guardian Hearts usually appears when Kazuya is getting along with a girl. Not knowing that Guardian Hearts is actually Hina, they leave her alone with Kazuya in an attempt to lure Guardian Hearts.<br><br>
