Legend has it that in the imperial capital of Tokyo, there is a mysterious Yin-Yang family, with origin as its surname, color as its name, dreams as its ability, and specializing in spells. Inherited from the Heian Era thousands of years ago, it is an old enemy of the great nightmare demon Suzu.
Thousands of years later, this generation of dream spellcasters is named Suiyuan Qinglan, and the only shikigami is named Kyōka Suigetsu, or Kyōgetsu for short. The strongest of the younger generation of the Dream Tapir clan has a mysterious cousin named Kirigakure Rei. In the process of strengthening the seal on Su Ling, I accidentally encountered a strange monster who claimed to be married, and was sent to a thousand years ago...
Inexplicably, he fell into the courtyard of a man who called himself Abe Seimei. He was inexplicably involved in a monster incident. He accidentally used a dream-based spell in front of Seimei. He was inexplicably recognized as a miko with a psychic constitution. Inexplicably, he ended up living in that Seimei's house...
Facing this assembly line-like development of God, Wei Lan silently said: Cousin, please save the child! The child doesn't want to play anymore... Also, I obviously look more like a girl, but I'm really not a girl!
Facing Yamata no Orochi and Su Suzu from a thousand years ago, Wei Lan was speechless; Kirigakure Rei, who had a strength comparable to that of a great demon, actually appeared a thousand years ago, and his appearance and personality were no different from Kirigakure Rei a thousand years later. It seemed that Yamata no Orochi still knew him...
What is going on? Who is the mysterious cousin? And that Kaguya Shiro, why does he seem familiar...?
