うちのクラスの女子がヤバい

During puberty, teenage girls may experience the bizarre phenomenon of "useless powers". Such pointless powers triggered by various emotions may include fingers that turn into squid like appendages, becoming a stuffed animal when seeing something cute (like a horse?), making onigiri that erases memories, and other completely useless things. Note: to coincide with the physical release of the sequel, the original series was re-released in a single volume titled 1-nen 1-kumi Uchi no Class no Joshi ga Yabai.
