It took me six reads to understand it, so I'm just gonna spell it out here for anyone as dumb as me:
Wtani isn't spiritually perceptive in the slightest.
Mta (young-looking guy) is still alive. So is Akawa. "Main" guy (dyed-looking hair) is dead and doesn't realize it.
In panel 3, Wtani isn't reacting to main guy, he's reacting to Akawa coming in, where he notices Mta.
