Fiore

He was one of Darien's friends after Darien's parents died in a car crash. After Darien had given him a rose as a goodbye present, which as it turned out is because Fiore's kind cannot breathe Earth's atmosphere much longer, Fiore searched the universe for a flower to give to him in return, which was the Kisenian Blossom. The Kisenian Blossom had tricked Fiore into believing that since Serena was his girlfriend, he couldn't be friends with Darien and take him over.
