They claimed to be visiting students from Haven, but I suspect that part was a lie. I didn't watch their first tournament match, but they fought Coco and Yatsuhashi from team CVFY in the doubles round.

Then Mercury fought Yang in the singles round, and that jerk - those jerks - messed with Yang's head. She would never hit someone when they're down, not normally, but whatever they did to her pushed her to do it.

She got disqualified from the tournament. That's really when things started to get bad...
