Tsuyoshi, the second son of the hardcore Yankee family "Namba Family", actually said "I want to quit Yankee" and "I want to be a normal high school student". In front of his family, Yankee Tsuyoshi, who wore special clothes, started a double life as a serious high school student in uniform at school. There, he joined the art club as an honor student, but I couldn't leave my friend being bullied, and when I changed into a special attack clothes and helped, I was steadily rising as the strongest unidentified yankee. The cracks in human relationships that arise from double life, and the anguish ... but the friendship and family love that arises from them! It is drawn novelly as a completely new youth yankee drama.
