Kurokamen, secretly Macht Ewigkeit, operates behind a mask, his obscured face rendering his expressions and motives initially veiled in enigma. His actions and words often appear deliberately unclear, yet his partner, the Magus AI Schnee, exhibits profound understanding and trust, enabling their seamless collaboration. Born in Amasia's underground city, he is the elder brother of Tokio, later known as Licht Alter. Both siblings were recognized as skilled drifters, pilots of mechanized Cradles battling Enders to collect AO Crystals. Their bond shattered when Tokio attempted to flee Amasia, culminating in a confrontation where Tokio seized a weapon, threatened Macht, and escaped. This betrayal instilled lasting animosity, causing Macht to display uncharacteristic anger and impatience specifically toward Tokio, contrasting sharply with his otherwise calm and patient nature. As Kurokamen, he adopts this masked identity, frequently opposing Tokio's endeavors. However, his underlying history and familial connection drive a complex transformation. Despite their conflict, Macht ultimately reconciles with Tokio, forging an alliance with the protagonist Kanata and others to confront the antagonist Weisheit Blaurecht. This shift from adversary to ally underscores his dedication to larger survival objectives beyond personal grudges. Throughout his journey, his essential partnership with Schnee remains constant, her unwavering trust facilitating their tactical coordination. His development culminates in defending humanity against existential threats, leveraging his expertise as a drifter and intimate knowledge of Amasia's societal struggles.
