Don't get the wrong idea.

Is this a barrier? Is this to prevent anyone else from our team to join in? Or is it to prevent her team members to come in here...

This barrier is the same as yours. It's built so it doesn't allow the opponent to escape.

Well, you're my opponent now isn't it? It'll be a trouble for me if you try to run.

Heh, talking big for someone who's outnumbered.
