Yu-Gi-Oh! Spirit Caller?

Question

How to register someone? I hate to duel some like Jasmine, Mindy and previous duelists..

I want to avoid them, I had battled Ryouka Tanaka 11 times, and Im sure i have registered him, it is just that i dun know how to prevent him from appearing in my map...

Answer 1

Just keep dueling them, eventually they will register you and you won't have to worry about it anymore. 10 times or so should let them befriend you.
