As Hibiki is spending more and more time fighting the Noise, it means less time for her studies and less time for her friends.  Miku is feeling alone and isolated, but she makes a promise with Hibiki to go get some snacks after school.  But when school ends, Hibiki gets another call...
The song in my heart!
الأغنية التي في قلبي
Das Lied in meinem Herzen!
¡La canción de mi corazón!
¡La canción de mi corazón!
Questa è la canzone 
che risuona nel mio cuore!
A música em meu coração!
