I don't really get the V-Tuber thing (other than wanting to stay anonymous) but having code explained to me by an anime character is hilarious.
He's been clear that he's not Asahi Lina... and he's also not a GPU hacker as far as I know.
I'm not really willing to indulge the greater discussion, but marcan has done some serious GPU hacking before, reverse engineering the microcode (not shaders) of the PS4's GPU to fix bugs that the PS4 hacked around in the drivers.
He even did a super-cringe "take over" video, where Asahi Lina "broke into" one of streams: https://www.youtube.com/watch?v=effHrj0qmwk
I honestly find it very hard to take someone seriously who chooses this kind of persona, even though it's hard to argue with their technical ability and results.
You cannot be this gullible. "Asahi Lina" is a pseudonym for Marcan.
/home/marcan and /home/lina on the same box.
I have no specific knowledge, but it seems very clear to me that at the very least marcan is a collaborator in the persona of Asahi Lina; and absent further contrary evidence, them being the same makes sense.

¹ And if stream key exfiltration actually happened, I find it hard to imagine anything but acrimony arising.
Probably some pre-recorded, agreed upon advertisement to promote a new channel.

He/she is quite the creative person I must say.
