Yoko JUST announced it on Recommen and they will be playing it ON AIR next week! YAY!
It will be released in March 12!!!
There`s also a coupling song, but we don`t know anything other than that it is `yabai.` (As Yoko said many times haha)
EDIT: Coupling songs are 「BJ」& 「誰より君が好きだから (Dare yori kimi ga suki dakara)」(maybe?) for K8`s single <3
