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.

When Kimura Kazuki was pondering over this, her gaze landed on Furuhashi Sakurakyu, who was the mother of quadruplets.

Furuhashi Sakurakyu was also watching Kimura Kazuki. Knowing that she was a specter, she could feel that both of them were very emotional.

However, as Kimura Kazuki was looking at her, she was able to stay composed and converse with him naturally. It was clear that he was not as simple as an ordinary student. So, as she saw that he was looking at her, she smiled gracefully and knew that he must have questions in mind for her.

As expected, Kimura Kazuki asked, "Miss Furuhashi, do you know how long you have been inside this jade pendant?"
