English translation of lyrics from the Takarazuka original production based on the manga and anime characters. (Translation by kittychan with some editing by chemicalperfume.)

Lupin:
If you’re going to be a deceiver, deceive the whole world
If you’re going to steal, go for the world’s greatest treasure

Keep a fire in your heart and a lie on your lips
Sharpen your teeth and claws–that’s a man’s aesthetic!

Ah, doesn’t it make your heart sing?
This adventure…

After all–
We’re only poor Aventuriers
We’re adventurers
We party and make noise and have fun with life
Come along with us!

The world is a limitless playground
Let’s start the game

Jigen:
When I’m holding my hot Magnum
I can have sweet dreams
I’ll cut through the darkness
And seize tomorrow

Goemon:
If you want to protect something
you must fight for it
In every man’s life
There are these moments

Trio:
After all–
We’re only poor Aventuriers
But even so
We won’t forget our desires, hopes and dreams!

Lupin:
Open your eyes
There’s no time to live as if you’re already dead
Come on, the game is starting!

Cagliostro:
Ah~ the passion I thought was gone
Is burning in my heart

Lupin: Come on!

All:
That’s right
We’re only poor Aventuriers
Aventuriers who just want to have fun
Chasing dreams that might be foolish, we’ll live cheerfully
The treasure will be ours!
