Samurai Champloo

A young woman named Fuu is working as a waitress in a tea house when she is harassed by a band of ruffians. Another customer, Mugen, offers to take care of them in exchange for food, but ends up instigating a brawl. Jin, a stoic young ronin in samurai garb, enters the tea house in the midst of the fight. Mugen accidentally swings at him and they begin fighting one another, ignoring a fire that started during the brawl. They both faint from smoke inhalation. When they awaken, they find they have been arrested for the arsonous murder of Shibui Tomonoshina, the magistrate's son, and are to be executed. This is the Champloo series. I have been watching it for 3 years now, and I love it.
