Sakaki Ayaka is a high school freshman who possesses the unusual ability to cause objects to break through resonant vibrations. Despite this, she has largely maintained a normal life, though her unique power occasionally leads to peculiar incidents. Recently, Ayaka has begun hearing a voice in her head. This voice belongs to a legendary giant tuning fork, which offers to help her develop her abilities. It also informs her about a powerful individual known as the Keymaster, suggesting that Ayaka herself could become very powerful with training. Her new teacher also seems to be involved in these unfolding events.
