Seirei Gensouki

Seirei Gensouki: Spirit Chronicles is a Japanese light novel series written by Yuri Kitayama and illustrated by Riv. It was serialized online between February 2014 and October 2020 on the user-generated novel publishing website Shōsetsuka ni Narō. 

Haruto Amakawa is a Japanese college student who died in a train crash before he could reunite with his childhood friend, Miharu Ayase, whom he hadn’t seen in five years. Next thing he knew his memories resurrected in the body of a boy, Rio, living in the slums of the Bertram Kingdom in the Stralh region of another world. Two people with entirely different backgrounds and values—Rio wants revenge on behalf of his mother, who was murdered in front of him. Complicating matters, Rio suddenly encounters a kidnapping involving the two princesses. After Rio is cleared of abduction, the royalist rewards him with acceptance to the kingdom’s academy for studying magic and swordsmanship. However, Rio is shunned by most of the peers there due to being a peasant. His only companion there is Celia Claire, a young female teacher who invites him into her laboratory on a daily basis. Before graduating from the academy, due to a false accusation, Rio became a fugitive and was forced to flee the country. He promises Celia that he will return once he travels to the far east of his mother’s homeland to find his roots and stabilize his mixed personality. Along with Haruto’s memories, Rio awakens a “special power,” and it seems that if he uses it well, he can live a better life.
