空は青さを失うだろう。 the sky will lose its blueness.

不幸せが今の幸せの土台だとしたら 

その愚問が世の中の曲解した奇を照らす。 

鯉も掴めない空を登り武者に還り 
人が虚空を指差し 
青いと言えば空は青さを失うだろう。 

If unhappiness is the foundation of the present happiness 

That foolish question illuminates the mysterious curiosity of the world. 

Climbing the sky which the carp can not grasp, becoming a warrior 

A person points to the empty space 
Speaking of blue, the sky will lose its blueness.
