Reincarnated Mage with Inferior Eyes: Breezing through the Future as an Oppressed Ex-Hero Volume 5 by Yusura Kankitsu

Good grief. My whole life I’ve been looking for someone I can trust, but in the end, they always betray me, one way or another. Even my own party members—people who I fought and risked my life with—ended up kicking me to the wayside, and now I’m used to it. I thought two hundred years might change things, but the only thing that’s changed is how strong mages are. Now, I’m a student in a world where mages are remarkably weaker than in the past. My only wish is to live a peaceful life, but things keep cropping up, and I haven’t quite gotten there yet. Even so, as a denizen of this new world, I’ll need to choose my path forward. Though I’ve mostly lost faith I’ll ever find someone I can truly trust, I still hold on to the hope that one day, I will.
