Zhuge Kongming was regarded as one of the best tacticians of third-century China's Three Kingdoms period. Kongming, who has led his army to several difficult triumphs, gets seriously ill at the Battle of Wuzhang Plains. The exhaustion and remorse caused by the seemingly never-ending battle catch up with Kongming, and as he takes his dying breath, he hopes that if he were to reincarnate, he would be born in a more peaceful age. Kongming's request is granted, and he awakens in modern-day Tokyo with a youthful body and his memories intact. He stumbles into a nightclub and encounters Eiko Tsukimi, an aspiring singer whose performance quickly captures his attention. Eiko takes Kongming under his wing, pitying his perplexity.
