After you get the Crystal Cluster and repair the Teal Mask, you have to confront the Loyal Three to retrieve Ogerpon's masks.

After the Crystal Pool

After you get the Crystal Cluster at the Crystal Pool and complete the events that follow, the Loyal Three are marked on your map. You can battle them in any order.

Okidogi at Paradise Barrens

Go to Paradise Barrens in the northwest part of the land of Kitakami, then go north to find Okidogi. When you approach, there will be a cutscene. Then you and Carmine will have a double battle with Okidogi. You can't catch Okidogi, so just focus on defeating it.

Afterward, you get the Cornerstone Mask. Your pokémon will automatically be healed up.

Munkidori at Wisteria Pond

Go to the Wisteria Pond in the southwest part of the land of Kitakami, then go south to find Munkidori. When you approach, there will be a cutscene. Then you and Carmine will have a double battle with Munkidori. You can't catch Munkidori, so just focus on defeating it.

Afterward, you get the Wellspring Mask. Your pokémon will automatically be healed up.

Fezandipiti at Fellhorn Gorge

Go to the Crystal Pool, then go north down the slope, then go southeast, down the ladders, and continue going southeast to find Fezandipiti. When you approach, there will be a cutscene, and Fezandipiti will fly into the nearby cave. Go into the cave and follow the path. You can battle Yoshino the Festival Girl, who has a level 28/63 Goomy. You get 2520 Pokédollars for winning.

You can optionally explore this area, but when you're ready to face Fezandipiti, go east to the lowest part of the cave and go through the tunnel there to find Fezandipiti. When you approach, there will be a cutscene. Then you and Carmine will have a double battle with the level 35/85 Fezandipiti. You can't catch Fezandipiti, so just focus on defeating it.

Afterward, you get the Hearthflame Mask. Your pokémon will automatically be healed up.

After You Get the Masks

Afterward, Kieran asks you to go to the village, so Fly to the Community Center (or go to the destination on foot). There will be a cutscene.

Now fly to Infernal Pass and go northeast up the slope to reach the Dreaded Den. Approach the den and there will be a cutscene. Kieran will challenge you to a battle.

Battle Kieran

Talk to Kieran to start the battle. He has a level 33/71 Shiftry, a level 33/71 Probopass, a level 37/72 Yanmega, a level 38/72 Poliwrath, a level 37/76 Gliscor, and a level 36/72 Dipplin. You get 5776 Pokédollars for winning.

Catch Ogerpon

When you're ready, talk to Ogerpon and will battle it. It is level 20/70. Ogerpon will Terastallize at the start of the battle. The mask it wears will determine its type. The Teal Mask makes it Grass Tera type, the Hearthflame Mask makes it Fire Tera, the Wellspring Mask makes it Water Tera, and the Cornerstone Mask makes it Rock Tera. When you defeat one of its forms, it will switch to another form. After you defeat its Teal Mask form, you can catch it. The catch is guaranteed to succeed, so use whichever type of pokéball you like.

Afterward, go to Loyalty Plaza and talk to Carmine. She asks if she can battle Ogerpon. You can change Ogerpon's mask by giving the mask to Ogerpon from your inventory. Ogerpon will transform based on which mask she is holding. If Ogerpon isn't holding a mask, she will automatically wear the Teal Mask. Ogerpon's "Ivy Cudgel" move will change to the type that matches her current mask. Make sure to heal Ogerpon, then when you're ready, go back to Loyalty Plaza and talk to Carmine to start the battle. You need to have Ogerpon in your party, but it's OK to switch pokémon during the battle. Carmine has a level 33/70 Mightyena, a level 34/72 Ninetales, a level 33/71 Morpeko, a level 35/74 Sinistcha, and a level 34/72 Leavanny. You get 1960/5920 Pokédollars for winning.

Go to the Community Center

Go back to the Community Center. The Caretaker and the others are in front of the building. Approach them, and there will be a cutscene. You will receive a Kitakami Mochi Set. This ends the main story of The Teal Mask. Congratulations!

Post-Game

Now that you have completed the main story of The Teal Mask, there are some new things to do:

• Catch Okidogi, Munkidori, and Fezandipiti. They will be in the same locations where you defeated them before.
• Talk to Kieran and Carmine's Grandmother to get more jinbei.
• Buy masks, glasses, and phone cases from the mask stall at Kitakami Hall.
• Talk to the Caretaker at Kitakami Hall to donate to the Loyalty Plaza restoration project. You get a flashy jinbei and an emote for reaching the donation goal.
