Taken from translator website:

I was a cicada. Now I’m a dragon.
I who was reborn in a far place of a different world, was given life as a dragon. As this world’s one and only strongest dragon.
Why the cicada was reincarnated as a dragon, i didn’t understand,
or if I had received life again in order to meet her someday.
For her, I will sing again and again. Till the end of my power, till the end of my life.
