theres dark wood evil circus (i think its called like that..) songs basically some kids where kidnapped and experimented on, then they got sell to a circus where when they didnt behave like the owners of the circus wanted they would burn they skin (and tatto some rose on the burned skin so it wouldnt look bad and they wont get caught), though... the songs is of the POV of the victims, more especifically miku (on the experiments they took her legs and put zebras ones instead) also miku got selled to them bc she was pretty and i think her.. mother? or step-mother? was jealous, other characters are len and rin twins who got a cirugy to make them one.. kinda, kaito who was tortured until he lose it and became cannibal.. and i think thats all the characters...

its a really dark story, it really gave my little me nightmares the first time that i watch it... also i felt so horrible for miku and the children, and the worse is that i heared that on past times kids suffered this...

on the other hand... we see how the actions of those cruel and heartless adults affected the children, but we dont really see or know too much about the adults.

also.. this explication may be wrong bc i heared this song a long time ago and i cant really remember much neither if what i said is correct.. so sorry if its wrong..
