Hiroki Kurogane never asked for a second chance at life, especially not one that begins with pain, memory loss, and a strange book. After a strange accident pulls him from modern Tokyo into a world unlike any he's known, Hiroki awakens in a place known as Yumix, in a world of conflicts and hidden supernatural forces.

With no clear path and the danger closing in, Hiroki meets with a mysterious white-haired girl in his vision called Ayuri, whose her true motives were concealed behind her golden eyes.

Now Hiroki must uncover why he was brought here, and what his presence has awakened in a world that may not be ready for the answers.
