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.

Kimura Kazuki had always wondered why the four girls would suddenly refuse to study even though they had agreed to be homeschooled by him.

He thought that they were just making a fool out of him, never would he expect this was the main reason.

Apart from their academic abilities, Furuhashi Harunaka and the girls were quite perfect. Although they were born rich, they did not behave like spoiled brats. Furuhashi Natsui used to be a delinquent, but she was only trying to seek attention from others.

It was natural for Kimura Kazuki to feel grateful toward them. Before he had mastered the Yagyu Flying Sword Style, his salary as a translator was not sufficient to cover his monthly expenses. Being their home tutor had helped him to overcome the hardships during the early stage of his practice.
