Reincarnated Mage with Inferior Eyes: Breezing through the Future as an Oppressed Ex-Hero Volume 4.5 by Yusura Kankitsu

Before I reincarnated two hundred years into the future, before I even helped to defeat the Demon King of Twilight, I was just a young mage doing my best to survive in a world that hated me for the eyes I was born with. Along the way, I met some people who would become my reliable allies, in a party known as the Great Four. This is the story of who we were before we became heroes.
