Disciple of a Demonic Cult 

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.

Tentatively, he set out to hone himself to the bone, burning candles at both ends to stockpile resources in preparation for the imminent Recuperation of Reiki. His goal was to be many steps ahead of all humanity when the time comes.

However, it seemed like fate had decided to play a cruel trick on him.

One year later, the Recuperation of Reiki... did not happen as expected.

Upon hearing these words, the Kimura Kazuki of the past would have felt like he had received some advice from a sage, but now he could naturally understand it.

After he became a private tutor, he thought he could take advantage of being a cultivator to improve the Furuhashi sisters' results.

However, it was easier said than done. Even though Kimura Kazuki felt confident as a teacher, he was still unable to make the Furuhashi sisters more intelligent. Since his teaching was of no help and the Furuhashi sisters refused to learn, Kimura Kazuki felt powerless.

Though it seemed futile, Kimura Kazuki did not give up. He went through many preparations and was entirely determined to improve the Furuhashi sisters' results.
