Our final team is also the one with the weakest divergence point, because no one knows exactly how the team in [LEAGUE REDACTED] got its name.
The final team in the Zenkoku League originated in Fukuoka, where the Rings currently play. The team started as the Pilots, as the owner had a relationship with Pan Am Airways, and wanted to honour that connection. That relationship went south, and the team was left looking for a new identity.
No one knows how they settled on this team name, but they've kept it ever since, including a relocation to the northern Tokyo suburb of Saitama.
Saitama Panthers

Found the logo as a concept on
Dribbble designed by Yury Orlov, recoloured to orange because we don't have an orange team in JPBO right now.
Found the font he was using, Hardsign, but only the Layered version is freely available for personal use. That's what's on all the jerseys and the small logo.

Another three-uniform set - home white, road orange, and a black panther alternate that eschews a team name altogether.
The panther itself is from here.
And that completes my set of uniforms! The top post has been updated with
the link to the complete A Set mod.
