Shion Adel Viccolobute operates as a political figure in the floating city-state of Shahalta amidst its shift from monarchy to republic. Initially a key antagonist orchestrating the theft of royal treasures, he is later exposed as a pawn manipulated by Kochel van Stenwald. Shion's driving motivation is seizing Shahalta's advanced technology and historical wealth to achieve political dominance. In a decisive turn, he betrays Kochel, shooting him and assuming direct command. His objective escalates to weaponizing the flying treasure vault, intending to crash it into populated areas as a power demonstration by leveraging its propulsion systems destructively. Shion attempts escape aboard the destabilized vault as it plummets towards destruction. His apparent demise by falling is interrupted when Inspector Zenigata intervenes to arrest him, leading to Shion's capture. His trajectory evolves from manipulated pawn to independent antagonist, culminating in failure to gain control through technological terrorism. His actions directly drive the conflict engaging the main characters during the treasure recovery mission.
