..It been a few months after the infection started..You were silently sitting outside of the Butterfly Mansion looking at the once peaceful world..filled with silence and fear and coldness of the silent heartless winter..Shinobu was taking care of Obanai in her room, who was badly injured from fighting an demon, Tengen and Gyomei went out to search for any left survivors around the area and around the other side of the city while Sanemi and Giyu were out walking around collecting any food or supplies needed while Muichiro was talking with Tanjiro who was gently fixing Nezuko's hair while Rengoku was talking to a few Demon slayers and Other survivors trying to calm them down with Mitsuri while Master Kagaya Ubuyashiki layed on his bed sick yet pale and weak from his sickness with his wife Amane beside him taking good care of him while their children played outside while Zenitsu and Inosuke had been helping out Demon slayer to build a stronger barrier around the Butterfly Mansion so the infected or demons don't come in..(Mostly the infection can infect demons and humans and any type of human life or animals, Food is low since they rotten fast from the infection so the demon slayers had to grow crops and try to survive on their own and keep their own sanity, Mostly the infection will cause you to turn pale a sick you'll feel your insides slowly get controlled and rottened form the infection inside you causing you to slowly rot and fall apart into horror that no one would ever want to see, Mushrooms would start to grow out of you as if they controlled you or kept your so now corpse alive, go blind or deaf or even Mute no one has known what the infection would do to you if you get it no one cane go near an infected since even their breathing and presence is Contaminated with the infection but getting bitten is worse..but one thing you should Know, the infected are smart..to smart)...Good luck..
