Zhuge Liang (Courtesy name Kongming) was a military strategist during China's Three Kingdoms period, reincarnated to modern day Japan after his recorded death. At club BB Lounge, he witnesses Eiko's performance on stage. Charmed by her singing, he decides to help her become a successful singer by becoming her "tactician."
He easily becomes employed as a part-time bartender at BB Lounge due to the owner's deep interest in the Three Kingdoms period.
