Battle of Ice! The Cold-Eyed Grusha

It's finally time for Liko's practical application test. The group has gone to the Mt. Napper Gym so she can challenge Grusha, where they drop by the "Arukujira Slide" while waiting for the test to begin. There, the operator tells them about Grusha's past... And then, Liko, Nyarote and Tebrim get attacked by Grusha, the man known as the strongest Gym Leader in the Paldea region!
