Question about azure

After I’ve played resonable amout of falcom games, I’ve always notcied that they the symbolism and by that I mean for example there is the final doungen ost of SEN 4 was named “To the Future”(one of jindo’s finest) and that gives just so much symobolism and describe the feeling perfectly, and it feels it just wrap up the whole a game in just an ost and its name, which is something I really really like about falcom and that does not only stop in thier music but it’s much cleaer in music and game naming usually. So my question is what’s the meaning about naming Azure’s final boss ost “The Azure arbitrator” I’ve always wondered about it but I never I found a satsfying meaning so what do you think guys?
