11 years since the previous work. Former Roppongi emperor Kohei Nanase is back! Taisei Katsuragi entrusted Kohei with the world of the night, but two years have passed since he left it to his juniors, Shoji and Hideyoshi. Kohei suddenly hears of Hideyoshi's death and rushes to Roppongi. In that death, there is the shadow of Ginza's host club CEO Le Del Nero, who calls himself the "King of Black"... Kohei abandons his peaceful life and returns to the glaring stage. A new battle has now begun!

A former Koshien champion baseball player suddenly retired and returned to Japan, and became the mayor of the local city. He will propose policies that ordinary people cannot imagine, such as the issuance of community currency and the concept of a casino.
