Saal Cooper served as the family's shield, enduring injuries meant for Eren Cooper while remaining loyal and bound by magic. His role made Eren appear invincible, but once his usefulness ended, the family cast him aside. As he faced death, Saal uncovered the cruel reality behind his suffering and used his last strength to undo the spell. Instead of dying, he was reborn as a three-year-old. Now given a second chance, he aims to no longer remain in the background.
