Shiranui went inside the Mart and donned his Silph Scope so he could see any Ghost-type Pokémon for what they really were.  He defeated a Gastly, a Haunter and a Gengar in battle with the most recent one being the trigger for Ashika to evolve to a Primarina.  When he made it to the back of the Mart through the maze of aisles and shelves, he spotted a Mimikyu that was twice the average height and deduced it was the totem.

"Nayamashii, I choose you!"  Shiranui sent his Salazzle out and the trial battle was on.  "Nayamashii, start with Toxic!"  The Salazzle spat out some caustic toxins that left the totem Mimikyu badly poisoned and in retaliation, Mimikyu came up to Nayamashii and gave her a Feint Attack.  Mimikyu called out and a Banette showed up to be the totem's ally.  "Nayamashii, use Flame Burst on Banette!"  Nayamashii's tail ignited as the Salazzle breathed out a burst of fire that inundated the two opponents, leaving Banette scorched and Mimikyu with a broken Disguise.  Mimikyu gave Nayamashii a Shadow Claw and Banette pulled a gambit move with Curse, knocking itself out to put a curse on Nayamashii.  Nayamashii succumbed to the curse and was knocked out as well.

"Nayamashii, return; Bakeru, I choose you!"  Shiranui switched out his fallen Salazzle and sent out his own Mimikyu.  "Bakeru, use Shadow Claw!"  The totem Mimikyu leaped at Bakeru and started roughhousing with him.  Bakeru's Disguise was broken after that Play Rough and the normal Mimikyu gave the totem a slash with one of his ghostly arms.  The hit was critical and the totem Mimikyu was knocked out before it could call in another ally.

Shiranui gave Banette and Mimikyu a Revive each and enough berries to restore them to full health and in congratulations, Banette gave him a Mimikium Z and Mimikyu gave him a Ghostium Z before they showed him the dances to activate their respective powers.
