In 2025, Chen Hao, a 22-year-old history student, was struck by lightning while protesting outside Yasukuni Shrine against Japan's distortion of history. His soul transmigrated to Suruga Province in Japan, at the beginning of the Sengoku period in the late fifteenth century. In his previous life, Chen Hao's ancestors had been brutally killed by the Japanese army during the War of Resistance Against Japan, leaving him with a deep hatred of Japan. Transmigrated with a heart full of rage, he resolved to take revenge on the Japanese in this era. Japan during the Sengoku period was divided among warring feudal lords; the people lived in misery, while the nobility led lives of depravity. It was the perfect opportunity for Chen Hao to exact his revenge.
