hey guys,

i'm looking looking for the name of a manga or mawha where the apocalypse start monsters appear and everyone gets acces to a system

the main protagonist gets i believe a scout class wich evolves in to assasin a little bit later

and his signature skill is inventory wich he uses to drop heavy objects on monsters and crushes them
he also finds a dog which get a shadow control abilitys and a slime that transforms into clothing

also a girl with a sniper on a rooftop sends him messages to join up
