Seven years ago, after their breakup, he disappeared without a trace.

Once I’ve become Immortal, then my attempt to conquer the world shall begin.

Time travelling from the majestic era after the Recuperation of Reiki, he became Kimura Kazuki, a 16-year-old high school student in Japan, one year before the Reiki Recuperation.
