Three years ago, "extraordinary fragrances" that could not be smelled but could invade people's consciousness appeared in the world. They condensed into a pocket space - the fragrance world. Violators are assimilated and their consciousness is dissolved. The scent sniffers of the Scent Suppression Department use their skills as their blades and their five senses as their wages to go deep into the fragrance realm to crack the rules, and the source of all strange fragrances is far darker than anyone imagined.
Intention: People will learn to leave traces when they die - even if it is just a momentary touch, a trace of residual body temperature, a smell that others can smell. It's not scary to disappear. What's scary is that no one remembers you were there.
