Eiyuu Densetsu - Sen no Kiseki Comic

Thors Military Academy is a prestigious school in Erebonia, an empire marked by war, where noble and common-born students study together. First-year student Rean Schwarzer discovers that he and eight other students from very different backgrounds have been selected for experimental Class VII, where social rank is set aside. Tensions run high throughout the Empire, and Rean and his new classmates may soon be drawn into conflicts that reach well beyond the academy’s classrooms.
