Net King: I, the Blood Demon King of Rikkaida

Fujiwara Seiji, who once dominated German street tennis and was selected for Germany's U17, was nicknamed the "Blood Demon" because he had a berserker ghost hand on his left arm. After receiving an invitation from his childhood friend Genichiro Sanada, he returned to China to join the High School Affiliated to Rikkai University, with the goal of helping the team achieve three consecutive national championships. I thought that the junior high school game was just a pastime, but who would have thought that a mountain collapse smashed the court ground, a cross cut tore apart the regular ball path, and the rampage state directly crushed all kinds of talented players. Yukimura Seiichi marveled at his hidden destructive power, and Atobe, Shiraishi, and Echizen were defeated by the bloody wind one after another. When the Japanese junior high school tennis circle was shocked, the German U17 invitation arrived again: The world arena belonging to the Demon King has just begun.
