Episode 2 introduces Setsuna Aikokuin, who can transform into Gavan Bushido, despite Reiji initially believing that the title of Gavan belongs to only one individual. That creates one of the most important questions in the entire series: what actually qualifies someone to be a Gavan?

If different universes can produce their own Space Sheriffs, then “Gavan” may be less like a single identity and more like a role that can manifest in different realities. The series could eventually reveal a common origin connecting these apparently separate Gavans, potentially explaining why their armor and abilities share recognizable characteristics.
