Tena on S-string 5

All Kyousuke wants in life is to make music that puts smiles on the faces of others. But with he, Tena, and their friends imprisoned within the fortress-like walls of the Tuner Headquarters, that idyllic goal seems like nothing more than a pipe dream! And the nightmare shows no sign of letting up as the whole story behind the note retrieval missions comes to light, and the group find themselves lost for words and hope as Tuner Governor-General Gloria seeks to throw the world into chaos with a catastrophic "grand performance"! Will the curtain fall on Tena, Kyousuke, and the world as they know it?!
