Kazuya Aoike

Kazuya Aoike is one of Tsukushi's childhood friends and enrolls at Eitoku after his family becomes wealthy through real-estate deals. His classmates sharply distinguish his family's "new money" from their own inherited wealth, especially the F4. Kazuya is fiercely loyal to Tsukushi and has romantic feelings for her, though he is also rather slow to notice what is happening around him.
