Later, the group goes to the docks to meet up with Kiawe's sister Mimo, but find she is nowhere in sight. Sophocles, having spoken to the concierge, informs Kiawe that the boat arrived 30 minutes earlier. Kiawe rushes over to the Manalo Stadium, suspecting Mimo went there.
Meanwhile, Mimo is lost as she wonders atop of the stadium, when she spots Team Skull Grunt trio Tupp, Rapp and Zipp graffitiing the pavement. She orders them to stop, but the grunts decide to send out their Pokémon to deal with her. As they prepare to attack, Gladion's Silvally steps in and lashes the grunt’s Pokémon with an Air Slash. Gladion orders thee trio to scram. Tupp, however, refuses to back down until Gladion’s intimidating glare proves too much and the grunts leave. Gladion recalls Silvally to its Premier Ball. Mimo introduces herself, explaining that she hopes to see brother battle today. Gladion realizes Mimo is Kiawe's younger sister and escorts her to the stadium. Mimo grabs a hold of Gladion’s hand, causing Gladion to remember his own sister, Lillie, though he brushes the thought off. On their way, Kiawe rushes to hug his sister, overjoyed to see that she is fine. He then realizes Gladion is standing there, and Mimo clarifies that Gladion saved her from Team Skull. Kiawe thanks him, though Gladion replies that it was nothing. Lillie and the others suddenly arrive and are relieved to see Mimo is fine. Mimo apologizes for making them worry, though Kiawe remind her that next she should wait till he arrives. Gladion decides to make a move, and Kiawe replies that he will see him at the match. Mimo is left puzzled, and she is then shocked to learn that her big brother is facing Gladion. Kiawe assures Mimo that everything will be fine, declaring that with her support he will be unbeatable. Mimo, however, has her doubts.

On the battlefield, Kiawe and Gladion confront each other. Olivia steps onto the battlefield as the referee, but trips over. After recovering, Olivia declares that she wants to see the most out of both opponents, adding that both sides will now use two Pokémon. Kiawe calls out his Marowak, while Gladion selects Lycanroc. Kiawe makes the first move, but Lycanroc dodges, and jumps away as the Bonemerang makes its return. Lycanroc powers up with Swords Dance before unleashing a Stone Edge. Marowak evades the jagged stones and rushes in for a retaliatory Iron Head. Lycanroc is prepared as it strikes Marowak with Stone Edge, sending Marowak flying onto the field. Kiawe tries another strategy, and uses Flare Blitz to evade Lycanroc's Stone Edge defense before hitting it with an Iron Head. As Marowak leaps away, Lycanroc quickly recovers and responses with a Stone Edge to knock Marowak out of the match.
Mimo starts to cry, but instantly cheers up when Kiawe calls out his next Pokémon, Turtonator. Gladion has Lycanroc use Stone Edge, though Turtonator demolishes the move with its Dragon Tail and swats Lycanroc into a wall. As Lycanroc recovers, Turtonator readies another Dragon Tail. Lycanroc braces for impact, with its Counter staving off the attack and sending both sides backwards. The two sides stand back up, and Turtonator soon engulfs its opponent in a Flamethrower. Gladion has Lycanroc take the attack, causing it to enter its red-eyed state, before launching into an Outrage. Turtonator turns its back and Lycanroc rushes directly into an explosive Shell Trap, which takes Gladion by surprise. Lycanroc, however, is still energized and rushes in for another Outrage. Kiawe orders another Shell Trap, but Lycanroc bypasses Turtonator and strikes it from the front. Kiawe is in distress, as Outrage should've made Lycanroc uncontrollable. Lycanroc then unleashes a barrage of punches, striking Turtonator each time. Kiawe orders Turtonator to focus and endure the attacks. As Lycanroc takes a swing at Turtonator’s central hole in its shell, Turtonator unleashes a ball of energy which Caster announces was a Focus Blast. Kiawe is pleased and has Turtonator follow up with another Focus Blast which defeats Gladion’s Lycanroc. As the battle turns to a one-on-one clash, Gladion sends out his Silvally to take on Turtonator.
