Houki Boshi (From Bleach)

Looking up at the night sky alone, I saw a comet
Though it appeared and vanished in a second
When I think of you, my chest begins to hurt
I want to see you right now, but I can't fly through the sky

If perchance I could have become a comet
I would go flying through the sky
No matter what kind of tomorrow comes, this thought is strong
So my comet is unbreakable

As I was complaining about how hateful the rain was
Even now I still remember what you said
How, after the rain, the night sky is beautifully filled with stars
Thinking of that, I could even come to like the rain

If perchance I could have become a comet
I would always spill my overflowing light
As you look at the night sky when you're sad
I want to sparkle more so that you will smile

You are always fighting something by yourself
Being by your side is all I can do

If perchance I could have become a comet
I would go flying through the sky, surely
I would definitely reach you, with this single moment of light
Lighting up your present and passing through the sky
If I could have become a comet
I would surely stay by your side, at any time
