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 knew that everyone's personality was affected by multiple factors.

Mikito Hanzawa's parents died when he was a child, and after he grew up, his brother was always out working. It seemed that both of them were interdependent, but due to work reasons, Akie Hanzawa rarely took notice of his younger brother's daily life.

Therefore, external environmental factors were crucial to Mikito Hanzawa's development. He developed a submissive personality and his attitude of just scraping by as the days passed. Kazuki was sure that Mikito Hanzawa must have gotten used to being bullied during his years in middle school.
