Kouichi Madanbashi

Age: 16

He always says whatever he thinks and doesn't even care if it's in public. He is a real pervert and even touched his teachers breasts, because he didn't wanted to wear the school uniform.
His is one of the factors who can store powerful HI-ERO particles, but he also need to do perverted thing to Kyouko to increase his "Hi-ERO" powers when fighting.
