Seraph of the End: Guren Ichinose: Catastrophe at Sixteen (manga)

Story :  How far would you go to get what you most desire? For Guren Ichinose, a fifteen-year-old magic user born into a lowly clan, that journey begins when he is forced to enroll at an academy run by his order's mortal enemies. There, while endlessly tormented by his insufferably privileged classmates, Guren must hide his true strength and weave his way through intrigue and deceit amid the rising winds of war. This all-new manga adaptation of the standalone light novel prequels to the hit manga Seraph of the End follows Guren as he takes his first steps toward inevitable calamity-the apocalypse that ushered in the reign of vampires. It is a tale of catastrophe, of star-crossed love, lies, and the search for an escape from destiny. How far will Guren go, and what-or whom-must he sacrifice for his ambitions?
