Uchi no Class no Joshi ga Yabai

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.*
