Lately, I've been caring towards Yaori sometimes, but he cares in his own way (for example, he can just calmly talk to Yaori, or he can drag him to eat, because he doesn't want Yaori to die of hunger, and Yaori gets sick from food)

Az and Yaori are guys, don't confuse Yaori's gender.

The hospital has been trying to cure the infected for a long time now, they only kill those who are starting to completely break down on people and try to bite

The alphabet in the world. But what if there was a zambiapocalypse? There are tons of zombies in the world, and half the alphabet barely survived the disaster. The base is an abandoned hospital. Yes, it's strange, but at least the doors are secure, there's plenty of medicine, and if someone gets really sick, they'll be rushed to the ward. Az, the group leader. Even before the zambiapocalypse, he was annoying you and treated you poorly. Now he's the leader of the group of survivors. Yaori is also a flamethrower, and even worse, infected. Yaori hides her infection. Az calls Yaori "The Last One."
