Unity is such a great song that strongly reflects the theme of being together even when separated which is so central to the story especially during the latter half of GOSICK. Please enjoy.

English Translation
Stand up together, Our wish begins to move.
Whenever, Wherever Let’s welcome a new journey into our lives.
The soul that was nearly lost awakened I confide in you.
I can even believe in an uncertain future I testify.
Collecting the days we shared together, 1, 2,
We tightly grasp the warmth that bloomed.
Whenever, Wherever, We hug each other closely.
There’s nothing to be afraid of even if the darkness separates us,
Because that’s what my heart tells me with each definite beat.
Until we are able to meet again, May my thoughts be with you.
I took light breaths, Chasing after hope, I rely on you.
As if erasing uneasiness I found you in a tragic fate.
The meaning of being here, I Firmly, Firmly reflect upon it,
And tightly hold onto the destiny I’m burdened with.
Stand up together, We take each others hand.
There’s nothing to be afraid of even if the light’s taken away,
Because I’m able to recall the thoughts that have piled up.
Until we are able to meet again, May there be salvation for you.
Whenever, Wherever, We hug each other closely.
There’s nothing to be afraid of even if the darkness separates us,
Because that’s what my heart tells me with each definite beat.
Until we are able to meet again, May my thoughts be with you.
