Punch her again

You do not let her blocking your previous punch deter you.

While her partner, the Indian girl, as well as your own friends, watch on in shock, you wind back and strike a powerful punch to the black girl's head that sends her to the floor.

Seeing that this situation is serious, the Indian girl begins to intervene. For a brief moment you debate whether to immediately confront her or to run, which was your original intention anyway.

You decide there's no use sticking around in a bad situation and turn toward the exit, but you are again stopped when you feel a powerful kick into the back of your knee, knocking out your right leg and sending you to the floor again on your knees.

You glance back and see the Indian girl rapidly move toward you, apparently with the intent of restraining you.

At that moment, your friend intervenes. Michael, a tall, fit boy grabs the Indian girl from behind in a bear hug maneuver to keep her from striking you. This gives you time to get back up.
