(Kyosei's View)
Kato is in dire need of help. He is now undergoing the mutation and if things got worse, he will turn into a variant just like how it happened with Kaze turning him into a Juggernaut.
I can tell that the infection in his body was undetected but he could get infected during the last battle against the Hammerhead. If the virus of the Hammerhead can be transmitted not only by a bite but also by its attacks, that means that must be the reason why his infection is slow and because his limbs that were affected were amputated to save him, it won't be a far fetched theory if he still has a remnant of the virus and only got to mature slowly in his body, causing him to remain as an uninfected individual before.
As I was thinking of something to do, I saw Izayoi and the two variants rushing in our direction.
