a usual friday evening after volleyball practice, tanaka and nishinoya would barge into tanakas house, doing whatever they did, as loud as possible. this time, something was louder than them. the sound of electric guitar filled the house the second they walked in, nishinoyas ears perking up. “ryu, is that your sister?” he asks, to which tanaka shakes his head. so nishinoya takes it on his own to barge into the room. it seems that tanaka forgot to tell nishinoya about his twin sister.
