Так как японский маленько непонятен, вот дословный англ. перевод (без рифмы, увы)

I'll [bad word] a happy butterfly
 And I'll ride on the glittering wind
 Than [bad word] 
 [bad word] to see you soon
 It's best to forget
 All the unnecessary things
 There's no more time
 To be fooling around 

What the wow wow wow wow wow
 I wonder if we'll reach the skies
 But wow wow wow wow wow
 I don't even know what my plans are for tomorrow

After an endless dream
 In this world of nothingness
 It seems as if our
 Beloved dreams will lose
 Even with these unreliable wings
 Covered in images that tend to stay
 I'm sure we can fly
 On my love

I'll [bad word] a merry butterfly, 
And ride on the earnest wind
 [bad word] to see you 
where ever you are
 Ambiguous words are surprisingly handy
 I'll shout it out, 
while listening to a hit song 

What do you mean, wow wow wow wow wow? 
I wonder if it'll echo through this town
 But, wow wow wow wow wow 
There's no use anticipating 

After an endless dream, in this miserable world
 That's right, maybe not [bad word] sense isn't so bad after all
 Even with these awkward wings, dyed with images that seem to stay
 I'm sure we can fly, on my love.
