■Content Information

As of 2026, eight years after the establishment of the M.League, the mahjong world remains divided.
This book unravels the history of the formation of mahjong professional organizations to explain why they have not united.
Originally, there was only one professional organization. Why did it split into two, then three?
The author suggests that "emotions" played a greater role than the desire for power or money. The book exposes the truth, revealing the names of actual professionals, and detailing the emotions that drove individuals who dedicated their lives to mahjong, leading to the organizations' splits.
Reading this will not only help you understand the history of current mahjong professionals but also make watching broadcast matches more enjoyable and insightful.

■Highlights

Includes a dialogue between the author and Yosuke Ide, Takashi Kono, and Suriaro BOSS.
