Every so often, we get wild fluctuations in the Thymosphere. One species of Esper will run rampant, or a previously peaceful Esper will turn destructive, or some other unexpected trend will sweep through the world out of the blue. Last year, for example, the normally peaceful Lilyfly turned vicious and began swarming radars. These swarms tend to happen around holidays or times when human thought is focused on one particular subject.
This year, we’ve registered record high numbers of Banshee. Since we’ve gotten so many new specimens, I’ve had more opportunities to study these unique Shadow Espers. They’re frail ghost-types that look a bit like human females, clothed only in a thin white cloth that billows around them as they float. Their translucent hair trails behind their heads like a delicate cloud.
