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.

Kazuki left at 8.30pm, but of course, he would not demand any remuneration for the extra half an hour.

Before he left, he could feel how relieved Harunaka and the others were. Perhaps studying was indeed a tough task for them.

Moreover, he had brought two sets of test papers with him, one from the Senior High School Entrance Examination and another one from the Junior High School exam. He had left the Senior High School test papers with them along with a copy of his own Junior High School textbook.

He hoped that when he was here again the coming Wednesday, the Senior High School test paper would be filled with answers as they were allowed to refer to books and research for information. As long as they were earnest enough, they could basically find all the answers they needed from the textbook he photocopied.

They should be able to finish it... right?
