11. Hayate Matsudaira
Needless to say, Hayate is an otaku. He collects manga, anime DVDs, collectibles, and even figurines and action figures. From when he was seven up until his late high school days, he was obsessed with a character named Cool Blue Sky.
Even after having given up his obsession in order to concentrate on real life, he still continues to find a woman that resembles his past idol.
