Shuichi was born in modern society as an ordinary high school student. After losing his father, he struggled desperately to protect his mother and sister, but was brutally bullied at school and even lost his life in an unexpected accident. However, when he woke up, he found himself reborn as Lucas Ryan, a noble boy from another world! It seems that Lucas once incurred the wrath of the magic god and died without being granted magic. Shuichi's soul resides in Lucas's body, and at the same time, he receives the blessing of Mars, the god of war! However, in this world, magicians are revered and martial artists are looked down upon. Reborn as Lucas, he would rather not live a life of despise by those around him—that's the last thing he wanted! Shuichi will master martial arts as Lucas and seize glory with his fists.
