So i was listening to a song called "A tale of six trillion years and a night" and was wishing Roselia made a cover on this, my wish has been granted in the past. I just found out Roselia did make a cover on this (why do i find out now? this song is on JP, you guys all know i play on EN) Can someone tell me when this song got released on JP? (like, what event was taking place when this was released?)
