As an apprentice Gym Trainer to
Kabu at Engine Stadium, she hopes to achieve that goal but hadn't passed a single battle test. She battled against
Liko's Sprigatito and
Roy's Fuecoco in a Double Battle with
Kabu's Centiskorch. After Centiskorch defeated Fuecoco,
Kabu told her that her Gym Trainer test would be to finish the battle against Sprigatito but
Liko gave up the match as she didn't want to hurt
Wakaba by defeating her as she seemed to be winning the battle. After apologizing to each other,
Wakaba vowed to keep training.
