God Eater 3的OP歌曲是"When The Light Comes" ，歌詞全文如下所示：
When the light comes and breaks you free
Stars in the sky, the dark will never be the same
You're not alone, I'll be here forever with you
When the light comes and shines on your soul
Chorus:
It's a new day, a new start
The monsters are coming, but we're not scared
We'll fight back, we'll never fall
'Cause we're the God Eaters
Verse 2:
In the dark corners, there's a whisper of evil
We're the hunters, the ones who don't hide
With our courage, we'll take back our world
It's our story, our battle, our victory

It's a new day, a new start
The monsters are coming, but we're not scared
We'll fight back, we'll never fall
'Cause we're the God Eaters

When the light comes, we stand up tall
To face the challenges, we won't be held back anymore
When the light comes, we won't let go
This is our story, God Eater forever.
