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...
I'm so tired, I can barely move my legs...
أنا مُتعبةٌ للغاية لدرجة أعجزُ
 فيها حتّى عن تحريك ساقيّ
Ich bin so müde,
dass meine Beine nicht mehr wollen.
Estoy tan cansada que 
no puedo mover las piernas...
Estoy tan cansada que no 
puedo mover las piernas...
Moi, je suis tellement crevée
que j’ai le cerveau en compote !
Io sono così a pezzi
che fatico a muovere le gambe...
Eu estou tão cansada,
 molenga, exausta.
