Mahou Shijou no Sekai de Academy no Tensai ni Natte Ita

Born into modern society, Shuichi was nothing more than an ordinary high school student. After losing his father, he struggled desperately to protect his mother and younger sister, but he faced brutal bullying at school and ultimately lost his life in an unexpected accident. However, when he woke up, he had been reborn as Lucas Ryan, a noble boy in another world! It seems Lucas had once incurred the wrath of the God of Magic, lost his life, and was denied the gift of magic. Shuichi inhabits Lucas’s body with his own soul and, at the same time, receives the blessing of the God of Martial Arts, Mars! However, in this world, magicians are revered, while martial artists are looked down upon. A life of being despised by those around him, even after being reborn—he’s not having any of that! As Lucas, Shuichi masters the martial arts and seizes glory with his fists.(Source: Piccoma, translated)
