Meanwhile in modern-day Japan, a boy named Arata Hinohara is starting his new life in high school. He wants to put memories of his difficult past behind him, but things aren't going to be simple when he discovers a mysterious connection to the first Arata... While on a mission disguised as a girl, Hinohara becomes utterly dismayed when Shinsho Kugura takes a liking to him. Meanwhile, Hinohara's rival Kadowaki shows up and initiates a showdown! Will Kadowaki manage to best Hinohara?
