Yukari Kobayakawa, an accomplished author at the age of 17, writes with amazingly accurate details about historical Japan. As it turns out, he has the ability to slip into his past life in the Edo period - as a beautiful, renowned courtesan named Yumurasaki!

Seemingly afflicted by Yumurasaki's fatal illness of the past, Yukari begins to get very sick in the present day... Meanwhile, Mahoro vows to kill Satomi before he can kill Yukari (as she believes he killed Yumurasaki in the past)! Are these three fated to repeat their tragic connection?
