The Romance of the Three Kingdoms is known for the power struggle between the three kingdoms of Wei, Wu, and Shu, but in this manga, Wei, Wu, and Shu are just companies, and the heroes of the Three Kingdoms are just ordinary salarymen. The president of the large trading company Wei is obsessed with salaryman haiku. The president of the toy manufacturer Wu, which has been in business for three generations, is listless. The young president of the IT venture company Shu believes that "virtue is all you need, no money." It's always the employees working under these presidents who end up in trouble. But for some reason, they seem to be having fun, or is that just my imagination? The fun black company, Sangoku-sha, is born!!
