When the floor of the Higurashi Shrine cracked a space-time gap, and when the Shikon Jade fragments were stained with unfamiliar blood, the mysterious woman with the same appearance as Kikyo and no pupils in her eyes knocked on the door with the invitation of "another time and space".
Strange black blood oozed from the wound on Inuyasha's shoulder, a twisted spell was implanted between Kagome's eyebrows, and Shippo's tail gradually became transparent in the mirror - the reflection of the world in the mirror was swallowing reality, and each mirror contained a completely different fate: some Kikyo killed his companions for the Shikon Jade, some Inuyasha became Naraku's puppet, and some of them had already been enemies of each other.
"At three o'clock in the morning, the mirror will bloom and fall, and the first person to disappear will be the person you care about most."
In order to undo the curse of the mirror world and retrieve their devoured companions, Inuyasha and Kagome had to step into the rift in time and space. They will travel through intertwined time and space, face "themselves" who have gone astray due to different choices, and will also uncover the true face of the "fake Platycodon" - who is she? How does the "stolen thing" she talks about have any connection with the Shikon Jade and the past with Kikyo?
When the mirror image overlaps with the real body, when trust wavers in suspicion, this mirror world mystery spanning time and space will eventually reveal the cruelest truth of fate. And can they maintain their unchanging bond with each other in the reincarnation of mirrors, flowers, water and moon?
