[TOMT] This online anime game where you shoot a guy riding a bike into the air.

I just remember that when you start the game, a girl kicks you or punches you (a guy on a bike), sending you flying into the air. And you land on people start riding really fast...or something...can't remember. I just knew there were several characters, and a girl hitting you. It was on some website. I was like...8-11 years old, somewhere around there. Pretty sure the game wasn't for kids and I had no business on the site.
