Asahi is likely to be an antagonist, I feel. He's the cousin of Yotsuyu and we know that her family turned a blind eye to her torment. I'll be disappointed if Doma's sins end up being linked to Garlemald itself as that would be quite a cheap cop out - though I'd prefer Asahi to be an antagonist over a protagonist as I want the 'Larsa' figure to be a Pureblood Garlean.

I have my doubts that Asahi is the same individual shown clenching their fist in Garlemald's palace. Could that individual show up and expose Asahi as a fraud?
