Wataru Kurozuma

The true leader of the Big Spider whom someone believe that he died from the explosion two years ago from the incident of saving his comrades that has been captured alone. In the present, Mikoto and Kuroko encountered him on the place where skill-out is gathered. He's strong physically and mentally, and Mii Konori's crush since. He often said, "When it comes to a milk, it's definitely Musashino", a brand of a milk he most favors.
