Yaichi’s natural enemy is Yaichi Yamato, who is an all-rounder and has the nickname of “both swordsmen.” Yaichi asks General Ikuishi Mitsuru, who has the nickname of “Maestro”, to teach him and aim to become the same all-rounder before the rematch with him, who was defeated in the game after a long absence and is about to come three weeks later. Yaichi and Ai go to the public bath and dojo “Gokigen no Yu” run by Ikishi every day to practice. Not only to win the sword cutting, but also to prepare for the battle with the master who was called the strongest genius in history.
