Something was corrupting Kengo’s soul. And he didn’t want to listen to that demonic voice from the dude with that creepy mask. He was trying to make things right. Those girls were like prostitutes in the hot spring. And Kengo was trying to sacrifice his life to save the girls he loves and cares about. But Matsuriko and Aya-nee and all the girls didn’t want to see him die. So they saved him and there was a beautiful flower garden. Kengo wanted to set the poor girls free.
