The song, named "demian" is composed from inspiration of same title of novel written by Hermann Hesse.
The lyrics in English (Sorry for any mistranslated, awkward expression )

When birds fly over,
Winds comes from
where I languish,
I looked up my head
to see the sky

Chasing to foremost breathlessly
Now I know there's nothing
where I finally arrives,
I'm going forward without hesitation

It's not far away that free you up
from your shackle,
Against all wind and regrets,
as a bird soaring when it plummets,

Endless road, forgotten memories
Now I realized
the precious cannot be restored
only after I lost it
I'm going forward without looking back

It's not far away that free you up
from your shackle,
Against all wind and regrets,
as a bird soaring when it plummets,

Behind the bar, from the shackle
It's not far away that free you up,
Against all wind and regrets,
as a bird soaring when it plummets,

The mask we made became our face
Life is too short to mourn,
also too early to regret
Against all wind and regrets,
as a bird soaring when it plummets,
Go Forward Go, Go- Go Forward

Forgetting nights full of regrets
like a running kid,
Feel like being full of my heart once again,
once again
