just a tanong :P

i was wondering does anywhere on this planet exist an anime where the characters know that they are in an anime....i know, sounds pretty cool XD
to be honest, i saw a meme today, this meme: link
and asked myself this question, so....
or does exist a anime where "a widowed dad takes his 10 taon old daughter to the carneval, and then the apocalypse happens, so he has to fight demons and other evil creatures to protect her. and his dead wife is one of the 4 horsemen " --->omg sounds so epic !! :D
or the one with the loli attack xDD
ah, people are so creative these days ! :)
