His character song is so sad (Ｔ^Ｔ) I don't have the full version of it but this is the full translation:

"When the moon, the sun, and the city fall asleep
In the cold of the slippery darkness
I let the melancholy escape from my lips
Seeps into the gap between my nails

Why do you make such a sad face?
You don't need to worry anymore
Because I plan to disappear when the dawn breaks
I'll bury it far away

Along with the fear inside my heart
And the emptiness that turns my soul into ashes
I'll bid farewell to those woes
Don't cry and be silent
Could you please nod for me?

I can't wake up in this thick fog
The cold morning air that stagnates in the void
The seed of my anxiety
Will eventually eat away my heart

Because the wind from tomorrow will blow
Yesterday's impurity should vanish
Along with the gray snow that is falling
And the loneliness that turns my soul into stone

I'll bid farewell to those troubles
Could you please see me off with a goodbye kiss?

Open the window, a white dove now fly from your hand
If that dove can pass through the darkness
The light will shine on the Trafalgar Square
The soft scent of Lavinia's perfume

Even if everyone is afraid of me and hates me
And you are the only one who understand, that's enough for me
Don't cry and be silent
Could you please smile for me?"
