English:

"Spread Upside-down" Two worlds
One by one, stumbling repeatedly
In one and two's, the were brought
The sky and ground that were torn apart
We continued overlapping in our hands

The light of the begining is over there
Riding the wish, it will visit
Both of us, surely, someday....

"Resonating Upside-down" Two heartbeats
One by one, we exchanged words
In one and two's, we brought our hearts together
The sky and ground that were torn apart
We continued holding in our hands

The footsteps of the begining are over there
Riding the future, they will visit
Both of us, surely, someday....
