Before the School Duel

Sometime before the School Duel...
Chazz took a look at his deck wanting to know a effective strategy for the School Duel.
"Hello?" Chazz turned and saw Ritsu standing behind him.
"Oh hey Ritsu." Chazz greeted her.
"Want some help coming up with a strategy for the upcoming School Duel." She offered.
"Sure, that would be nice." Chazz accepted her offer. 
"I'll even train you for it." Ritsu added.
"Really?" Chazz was shocked.
"Absolutely. You need to be ready for it." She nodded.
Chazz felt compelled to accept her offer.
