Knights of the Zodiac (Saint Seiya), Vol. 3 — Masami Kurumada

The fiercest battles are often fought within the family, and there can be no greater foes than brother versus brother! When the Andromeda Knight Shun gets an unexpected visit from his brother Phoenix Knight Ikki, all hell breaks loose! Trained from childhood on Death Queen Island and psychologically twisted from years of pain and torture, Ikki has become one wicked warrior, blaming his brother and all that is good for his suffering. Armed with his band of Black Knight warriors, he plans to stop at nothing to achieve his sinister goals! Can Shun, Seiya, and friends stop him so they can return to their tournament--or could this spell the end for our brave Knights of the Zodiac?
