FLCL Furi Kuri : Fooly Cooly (Vol. 1)

FLCL - Fooly Cooly, is a story about a 11 year old boy, Naota, and his brother's strange girlfriend, Mamimi, and what happens when they meet a strange 20-year old woman named Haruhara Haruko who claims to be an alien. Most of the background music and soundtrack are rock songs by an excellent Japanese J-pop band called The Pillows, who are simply perfect for every scene they are in.
