Tekkon Kinkreet: Black & White (All in One)

"In the sprawling Japanese metropolis of Treasure Town as a Disney-esque corporate empire is slowly gentrifying the darkest of its corners, Black and White live like insane Lost Boys, twin cat-shamans of the city and yin to one another's yang.  Black is all action and cruelty, violence and rage; his maybe-brother White is love and magic, wonder and... well he's pretty violent, too.  They hop from rooftop to rooftop and power-line to power-line like punk rock avatar superheroes of their chosen home, tights made of junk and capes of trash their uniforms, the abandoned cars they sleep in their headquarters.  These two erstwhile boy-kings have, however, finally met their match as the cops, the crooks, and the corporate empire decide it's their turn to run the show."
