Hyouken no Majutsushi ga Sekai wo Suberu

Ray White is a former war hero known as the Iceblade Magician, but at Arnold Academy, he just wants to be a normal student. He keeps his identity a secret, but soon he finds himself unwillingly on the hunt for a suspicious spy.

Ray does his best to fit in and make friends. He befriends Amelia Rose, a proud but kind girl, Evy Armstrong, a muscle-brained boy, and Elisa, a shy bookworm. With his new friends at his side, he is determined to protect them and the people he loves, no matter the cost.
