罪之王冠的OP歌曲是《lost ones》，歌詞全文如下：
I was once lost ones among the masses
Living life through the eyes of shadows
Lost ones follow the beaten path
But I chose my own way
The world is built upon a foundation of lies
And lost ones are trapped in this game
But if you believe in what you are
You won’t lose your way home
Lost ones gather up the shattered pieces
Pieces of hope and dreams lost and scattered
Lost ones stand up and embrace the pain
Embrace the unknown
The world is built upon a foundation of lies
And lost ones are trapped in this game
But if you believe in what you are
You won’t lose your way home
For all we are and have we are lost ones
And we will rise up and we will fall
But we won’t be defeated by this world
We will fight for our own way
The world is built upon a foundation of lies
And lost ones are trapped in this game
But if you believe in what you are
You won’t lose your way home
Home lost ones don’t look back
Keep on walking towards the light
It’s not over until you say goodbye
And until then we fight fight fight
Home lost ones hold tight
This journey may be long
But we won’t lose our way
Through endless storms we will soar soar soar
