Anyone can help me finding a game I forgot?

it was a NDS game about some guys fighting each other for a girl in a city-street atmosphere kinda like jet set radio,the only gameplay moment what do I remember was painting a graffiti with the touchpad

The World Ends with You?

Is it The World Ends With You?

Hmm, a little vague...
Like TNRKAMUI and Swabbleflange said, it could be The World Ends With You.
Anyway, here's a video-list of fighting/action games: it could also be Futari Wa PreCure or Katekyoo...
