An absolute god-like champion and master with six titles of eternal qualifications. The Ryuo battle will be held in which the master will "challenge" the current Ryuo Yaichi. The venue for the first station is Hawaii, an island of everlasting summer. At the resort-like eve, Ai's 10th birthday is also celebrated, and innocent comments asking her to win are praised. And the first station that was greeted. The master sets up an unexpected "one-handed loss angle replacement" in Yaichi. Yaichi, who is familiar with this tactic, seemed to have an advantage in the situation ...

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! !!
