Rewatching again, okay, I feel like Evil is Kadota, and then he loses the belt and then Daiji becomes Live.

I have substantial evidence!

Kadota is holding the phone gun.

One of Kadota's teammates say "Will everything go alright?". Kadota responds by giving a very suspecting smile, "Yeah, everything's going to be alright." before he points his gun at his team.

The next scene we get of the FENIX team, everyone's knocked out including George. Kadota is missing. Daiji isn't responsive.

This is evidence that Kadota is likely Evil. Although, it could also be Daiji aaah
