Masato Kadowaki

Masato Kadowaki (門脇 将人, Kadowaki Masato) is the major antagonist of the series. He is the former best friend and now bully of Arata Hinohara. He had a intense hatred toward Hinohara since middle school, therefore he plays the major antagonist in the series. After Hinohara helps him defenseless against Ameeno, it is uncertain that Kadowaki now regrets about Hinohara.
