Born in the underground refuge of Amasia as Licht Alter following the apocalyptic Tears of the New Moon, Tokio escaped to settle in Rocktown. There, he took the talent-deemed Drifter Kanata under his wing, establishing himself as a mentor and brother figure despite his disruptive free-spirited hedonism. Tokio sports spiky blonde hair and yellow eyes, typically clad in wasteland-suited jackets. His open-hearted yet teasing personality coexists with heavy drinking and a fundamentally good-natured core. Though seemingly unreliable, he ranks among Rocktown’s most skilled Drifters, leveraging environmental tactics with peerless adaptability. His history intertwines deeply with Ideal des Himmels. Raised in Amasia to restore it, he rejected their ideology and betrayed Ideal twice—first by fleeing, then by infiltrating them under the alias "White Mask" alongside his Magus partner Mouton. Posing to capture Kanata and Ciel, he instead engineered their escape, opposing Ideal’s cost-blind revival agenda. Mouton counterbalances Tokio’s impulsiveness with hyper-competent formality, managing practicalities like finances. Her ultra-rapid calculation Magus skill grants temporal perception advantages that synergize with Tokio’s improvisational combat, sustaining their partnership through shifting allegiances. Tokio’s bond with Kanata defines his growth, marked by protective interventions—taking Enders’ hits in "Drifter’s Pride" and executing an Episode 11 rescue. His mentorship evolves into pride over Kanata’s progress, tinged with melancholy as the younger Drifter’s independence reflects their changing dynamic. A fraught history links Tokio to Macht Ewigkeit (Kurokamen). Their ideological clash and personal hesitations culminated in an aerial battle where Tokio and Mouton confronted Macht to resolve unfinished strife, forcing Macht’s conviction reevaluation and advancing Tokio’s reconciliation with his past.
