lets presume kvoth and fuji are in cahoots and kvoth saved Fuji
is there a benefit to it?
Well Kvoth said the only way fuji can be mafia is if he is GF... But GF isn't the only role to have invest immune.
That being said Kvoth could be lying, risky but doable, is there a benefit to it? Well if Fuji is a power role, pillar of mafia team then yes, you wanna keep that alive as much as you can, especially if you can trade it for lesser mafia
If Fuji is buyakuya i can totally see some kind of AOE/Multikill attack in his arsenal which is def worthy being saved.
Plus Kvoth could be playing invest that cleared Fuji so that other invests don't bother with Fuji. That being said if either dies other is doomed.

If those 2 aint in cahoots and Kvoth hit a invest immune person how can we be sure down the line Fuji gets discovered?
having a invest result is one thing, but Fuji's playstyle is something else. The fluff, lying about PR on prof and lying about the ability is just too much. He got called out for it and dropped his supreme being persona and gave a shit starting d2 to avoid more sus

All in all i still think Fuji is prime target to go down, yes if he flip town i will look supper bad, but i just feel like his actions and his play this game were too relaxed, like he was sure in case shit goes down he has a backbone to fall to
