In the Abyss, Parasites such as the Amaranthine-Deceptors rely heavily on perfect camouflage (their wings look exactly like flower petals) and floating around flower fields to latch on to targets and parasitize them. These flying insects are a huge risk to hybrid kitsune children and cubs innocently playing around the 4th layer. Trish creates these specific fans for children to ward off these flying pests and blow away the humid air.
