Kujira no Kora wa Sajou ni Utau [Stage Play 2016 opening]

I don’t know if it’s the OFFICIAL op nor if it’s the FULL version, I found this ost in a live video, so it’s not confirmed but I’m almost sure that it’s the real.

EDIT: so it’s not the anime official one but it’s the stage’s official opening 🙂
