Hyouken no Majutsushi ga Sekai wo Suberu

As the first commoner to attend the prestigious Arnold Academy of Sorcery, Ray White is immediately met with contempt from some of the students hailing from nobility. Unbeknownst to them, Ray's real identity is that of the famous Iceblade Sorcerer—a hero who led the country to victory in a past war and is one of the seven strongest sorcerers alive. Despite his legendary status, Ray wants nothing more than to live out the ordinary school life he never had. Ray quickly makes friends with some of the most influential students thanks to his kind and amiable nature. Unfortunately, as those with nefarious motives begin to make their move, Ray may soon have no choice but to use his true power to preserve the bonds that make his new life worthwhile. Everyone knows of the most powerful soldier, the Iceblade Magician, who led the country to victory three years ago, but few know his true name: Ray White. After weathering through a bloody war, Ray enrolls at Arnold Academy, ready to experience a normal life—a luxury he never had. To further this goal, he keeps his identity as the Iceblade Magician a secret, the scars of the past still haunting him to this very day.
