"Fire Mirage" is a Japanese TV animation work. It tells a series of bizarre stories that happened after ancient warriors were revived in modern society. Yang Mu Takaya is a high school student living in Matsumoto. He originally lived an ordinary and boring student life, but recently he found that many strange things happened around him. His good friend Tian Rang suddenly behaved strangely, so that Gao Ye felt that what he said and did was not what he usually did. What's even more strange is that one day, a man named Naoe came to Takaya and took him to see Kawanakajima. At the same time, he told Takaya and his true identity, and asked Takaya to assist him in completing his mission. Naoe told Gao Ya that their predecessors were all warriors in the Warring States Period. Because they failed to realize their ambition of unifying the world at that time, they died with regret. For more than 400 years, they have been resurrecting their souls with corpses. Naoe and Gao Ya are one of them. Now these warriors have been entrusted with a mission by the military god Uesugi Kenshin to continue the battle with the Dark Warring States. Gao Ye, who couldn't believe it at first, suddenly felt that he had a kind of spiritual power, so he had to get involved in this seemingly impossible war
