Driver of the Sea

When Taisei and his friends arrive at Kokura Station in Kyushu, they are greeted by Tsukumo Umikaze, the driver of Shinkalion N700S Kamome. Taisei and his friends immediately begin simulation training. However, during the training, Tsukumo's Vehicle Combination fails. The cause is not Tsukumo, but the new operators Katsuki and Adachi. Ochiai from the Ōmiya Command Office is appointed to be in charge of training these two.
