Yeah, okay, first off all, its not a virus reincarnation. It might as well be a ghost reincarnation since he has possession ability, and thats probably going to be his main thing... forever.
If you are going to do a virus reincarnation, at least make it about him being a virus instead of having possession abilities.
I have actually never been more disappointed in a series premise until now. I thought I was going to be reading an isekai with actual biology in it, and not just another isekai.
I guess I'll have to wait for my Pandemic manga where the POV is on the Virus. But I guess that might not sell because of COVID and everything.
