You know, instead of killing us, Rex Cavalier, you might want to check on Lost Property 771. She's crying again (3:14).

3:14 MEOWWWWWWWWWWWWWW

This is the song for the level, but it plays during the boss too. Just to be clear.

@Ray dere But thanks to English Patch. That vertical text in Japanese Language has translated into the horizontal English Language. Why do you exhume the forgotten legend? What prompts you to chill your vitality. filling your veins with artificial blood, in your search for that which does not exist? Do you find beauty in each reiteration, each time you have followed this path? You will find nothing but the scars that mar us all. Nothing but the remains of a long-dead river, drawing your gaze. We, the echoes of the past, feel it no more. Have you found reason for it once again? When all that remains is a name, abandonded by time, who will notice? Who will find it? Will the words lose their very meaning? Will you end the legend, one and for all? The forgotten legend, masterless and lost! YOU GOT INSANITY.
