What's the cause of these parodies? This one more disturbing than the rozen one though.

rofl this is amazing

omg. *dies laughing*

whos that cat girl? so cute!

The cause is that Renton's face is hilarious.

Also the cause is Nijiura.

catgirl is Sanada from ufo princess valkyrie.

who is the artist of that song and whats the title of it?

Quoting scoop from post #36687 , the flash posted before this, it's "Shounen Heart by Home Made Kazoku".

The vocals almost sounded like Shingo2 (Shing02? sp?) to me. If you like this song and you haven't already heard these albums you may like them. Nujabes "Metaphorical Music" and Tsutchie "Thanks for Listening" both of Samurai Champloo soundtrack notoriety.

hey thanks for the info,i actually found the video on youtube if anyone wants to see it heres the link: http://www.youtube.com/watch?v=xASP0z5jSxA

The song is Shounen Heart, by Home Made Kazoku.

The origins pool is giving me a nice dosis of nostalgia... this used to be awesome and still is.
