At the request of Kudan, the chairman of the Shogi Federation, Yaichi met Yasha Shinteni, a selfish young lady in the 4th grade of elementary school. Although it is a twisted and high-flying garment, the skill of shogi is quite good. Yaichi, who thought that the existence of his rivals would strengthen his relationship, secretly decided to welcome Tengi as a disciple. Yaichi trains his garment at the Shogi Dojo in the New World, refraining from being in a bad mood when he takes another disciple. Of course, Ai couldn't have noticed such a suspicious master ...

The 4th station of the Ryuo battle between the master and Yaichi, which is held at the hot spring inn Hinatsuru. If he loses here, Yaichi loses the title of Ryuo. But his heart was calm and clear. Aito, Ginko, and Katsura watch the biggest battle in Shogi history in the waiting room. And Tengi watching the online broadcast from home. No one knows the whereabouts of the game. Supported by the eyes of Ai who believes in the victory of the master, Yaichi challenges the fateful battle! !!
