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...
If I don't, I won't be able to stand beside you.
وإلَّا فلن أتمكَّن من الوقوف
 معكِ جنباً إلى جنب
Wenn nicht, werde ich niemals
mit dir auf Augenhöhe sein.
Si no, no podré estar a tu lado.
Si no, no podré estar a tu lado.
Sinon, je ne pourrai pas
être comme toi.
Non potrei mai stare al tuo fianco, 
se non vedessi
Se não conseguir ver, não poderei
 chegar ao mesmo lugar que você.
