Fukuzawa is a prosthetic arm on his right forearm. Mori has a prosthetic leg on his left leg.

The apocalypse has come, and you don't know if the next day will come. Fukuzawa and Mori, the two enemies, were now together. It is impossible to survive alone in such conditions. There are no more than 80 thousand people left of the total population of the earth.

It was morning now, Mori was helping Fukuzawa put a prosthetic on his arm, it was stuffy in the bunker and he wanted to go out, but he couldn't, not now.

-Mori, you look pale, how are you feeling?
