A swallowtail appears, like it's flying about
In the middle of a summer night, beneath the moon
Yellow representing the joyfulness, blue taking on the anxiety
Jet-black wings that resemble the ends of the world
I asked to a traveler: "How far will you go?",
"When will you be done with this?"
The traveler replied: "There is no end,
I can bring it to an end though"
It's a long time since I saw him off, having said
"Well then, take care"
He doesn't come back
And now I realized that
He'd be nobody but me
Having met up with you is enough
The world became filled with lights
I'd be fine if I could see you in my dream
I hoped I'd be the one to be loved
The world changed its look
The sky and the sea meet in the ends of the world
