Rōmaji
Ano hi hontou ni ushinatta mono tte nan datta kke?

Tou ni wasurete shimatta yo

Yuugure de futari sukoshi zutsu mienakunatte ite

Sore na no ni bokura kaerezu ni ita

Dokoka ni kowaresou na moroi kokoro

Tsuyogaru kotoba de ootte kakushite'ru

Ootte kakushite'ru

Sayonara aenakunatta tte

Bokura wa tsuzuki ga aru kara

Kimi no inai sekai datte hashiru yo

Itsuka no itami wo…

Koete…

Koete

English
What did I really lose on that day?

I forgot long ago

We lost sight of each other in the twilight

What's more; we were unable to return

Somewhere our brittle, broken hearts

Try to hide behind strong words

Try to hide

Farewell, although we couldn't be together

We will carry on

Even in a world where you no longer exist, I will run

Overcome… Overcome
