Eiko must impress an important music producer, but finding your voice is no easy tactical feat. Perhaps she’ll find a comrade in arms on the streets of Shibuya…

Eiko and Kabe are missing something — something others have but they don't. Under Kongming's watchful eye, each strikes out on a mission to discover what that something is.

Eiko and Nanami have struck an alliance, but opposing forces conspire to break them apart. Can they endure the enemy salvo, or will their truce collapse under the onslaught?

While Kabe engages an old rival in a rematch, Eiko marches headlong into battle against her own inner adversary, and Kongming recalls peaceful days past.

It all comes down Kongming’s final gambit. Eiko will take to the stage in a direct confrontation with her friend-turned-rival, but will Nanami hear the song in Eiko’s heart?
