Part 1: The Teal Mask

The player is invited to participate in a student field trip to the land of Kitakami. Accompanied by Ms. Briar, a teacher guide from the sister school Blueberry Academy, the player travels to Kitakami and meets Carmine and her younger brother Kieran, two Blueberry Academy students native to Kitakami. The player is paired with Kieran and tasked with visiting three signs telling the story of "the Loyal Three". Many years ago, the ogre-like Pokémon Ogerpon, who was wearing the Teal Mask, attacked Kitakami, but three Pokémon named Okidogi, Munkidori, and Fezandipiti sacrificed themselves to defeat her. Ogerpon was never seen again, and the villagers buried the three Pokémon in a shrine, named them "the Loyal Three", and have since held an annual festival to celebrate them. During the festival, Carmine and the player briefly encounter Ogerpon, who drops the Teal Mask before fleeing. Carmine stops the player from telling Kieran what happened, as he idolizes Ogerpon and she fears his feelings would be hurt if he knew he missed a chance to meet her.

The next morning, Carmine's grandfather reveals that Ogerpon was a kind Pokémon who, along with her original trainer, was rejected by the villagers due to their appearance. However, their ancestor, the village's mask maker, took pity on them and gave them four masks; the Teal Mask, the Hearthflame Mask, the Wellspring Mask, and the Cornerstone Mask, which they used to blend in with the villagers. However, the Loyal Three attacked Ogerpon's trainer and stole three of the masks. Ogerpon killed the three Pokémon, but before she could get the masks, the villagers scared her away out of fear she was attacking them. Carmine decides to make amends with Ogerpon by repairing the Teal Mask. However, they are unaware that Kieran overheard their conversation; the next day, he steals the Teal Mask and angrily confronts the player at the shrine over being lied to. After being defeated at the shrine, he gives the mask back. Suddenly, the Loyal Three are revived and head for Kitakami Hall.

The player and Carmine follow the Loyal Three there, but find that the villagers ignorantly gave them the masks and mochi which is implied to be infused with Herba Mystica, as it causes them to grow to Titan size. They then learn that the Three went after Ogerpon, intending to settle the score with her. Realizing Ogerpon is completely defenseless against the Three without her masks, Carmine heads off to repair the Teal Mask, while the player goes after the Three. The player and Carmine eventually resolve to help Ogerpon recover her masks, with the player bonding with Ogerpon in the process. While the player and Carmine pursue the Three and defeat them to reclaim the masks, Kieran tells the villagers the true story, and they apologize to Ogerpon. After returning her to her cave, Ogerpon reveals she wants to stay with the player, but Kieran demands to battle the player for her. After defeating him, the player successfully catches Ogerpon, leading a distraught Kieran to flee home and lock himself in his room. The next day, Briar announces that she, Carmine, and Kieran must return to Blueberry Academy due to a development regarding Area Zero, so the player and Carmine bid farewell to each other.

In a post-story scene, Kieran, now consumed by resentment, swears to get stronger and make the player pay for their perceived betrayal of him.

Part 2: The Indigo Disk

A month after the events of The Teal Mask, Clavell calls the player to inform them they have been chosen for a foreign exchange student program. They go to the Blueberry Academy in Unova, where they meet Director Cyrano and student Lacey. They head to the terrarium, an underwater biome beneath the school, where they attend a class. The player then gets a call from Carmine and the two meet at the central plaza. While catching up, they notice Kieran, who has changed his appearance and is yelling at another student. Carmine reveals that ever since they first met, Kieran has pushed himself and others to be the strongest they can be and has become dead-set on defeating the player. Later, the player meets another student named Drayton, who invites them to lunch. There, he reveals that he and students Amarys, Crispin, and Lacey, who are among the strongest students in the school, are part of the Blueberry League, and he wishes for the player to defeat their champion Kieran. After defeating all four of them, the player battles and defeats Kieran, becoming champion. However, the player is an exchange student and will most likely leave soon, meaning they cannot be champion for long. Just then the player, Drayton, Carmine, and Kieran are called to a room by Ms. Briar, where she tells them she has learned of Terapagos's location, believing it to be underneath Area Zero. She invites them to help her find it; Drayton decides to stay behind as everyone else decides to go to Area Zero, with Kieran hoping to catch Terapagos.

Upon arriving underneath Area Zero, the four arrive at a large crystalized tree and find a small yellow gem, which Ms. Briar identifies as Terapagos. Kieran vents his frustrations, bemoaning how he still has not beaten the player and that his gripe with them is not just because of their strength, but also their habit of making friends everywhere they go -including Carmine and Ogerpon- when he finally awakens Terapagos and catches it using a Master Ball. Ms. Briar then asks Kieran to battle the player with Terapagos, but the player defeat it. Ms. Briar realizes that he must Terastallize Terapagos to unlock its full power. However, this results in Terapagos going out of control; the player and Carmine battle it alongside Kieran before the player catches it. The four return to Blueberry Academy, with Ms. Briar apologizing for getting them all in danger and Kieran apologizing for his behavior.

After the credits, the player can take Terapagos to a crystal pool in Kitakami, where it uses its powers to bring either Professor Sada or Turo from across time. They talk with the professor, learning about their dreams and how they feel about Arven. The professor gives them either the Scarlet or Violet Book in exchange for a copy of a book Briar gave the player, before returning to their time, implicitly leading to the events of the games in the first place.

Epilogue: Mochi Mayhem

The player travels back to Kitakami with their friends Arven, Penny, and Nemona after receiving a letter from Kieran. The group arrives, only to discover Carmine acting strangely. The group sets out to find the source of her infliction the next day, but Nemona vanishes later that night. The player and Kieran find and pursue Nemona to Kitakami Hall, finding that the townsfolk have come under the same infliction as Carmine after eating strange mochi. The pair are called back to town by Penny and Arven, and the group encounters Pecharunt, a Mythical Pokémon who had originally been responsible for the Loyal Three's actions. Pecharunt sends mochi into Arven and Penny's mouths, and they fall under Pecharunt's control. Pecharunt has the two attack the player and Kieran, and after Penny and Arven are defeated, Pecharunt flees. Kieran and the player pursue Pecharunt, and the player eventually defeats a Pecharunt-controlled Nemona during a final confrontation at Loyalty Plaza. Pecharunt attacks, but the player defeats and captures Pecharunt, freeing the townsfolk and the player's friends from its control. A few days later, Carmine and Kieran leave for Blueberry Academy, while the player and their friends return to Paldea.

The Teal Mask

Pokémon Scarlet and Violet: The Teal Mask received a score of 65% on the Metacritic reviewing aggregator, indicating mixed or average reception.^[15] In comparison to the base game, The Teal Mask underperformed by 5–6%, which concludes that The Teal Mask performed noticeably worse than the base game.^[16] This is further cemented by HowLongToBeat, where The Teal Mask has a 66% rating, with an average completion time of 6½ hours on the main story.^[17] Reviewers generally felt that while The Teal Mask enhanced the main game's strengths, the Teal Mask also exacerbated the main game's weaknesses: IGN's Rebekah Valentine cut to the chase on the game's volatility, such as "...the overall ugliness and performance issues did detract from locations that looked like they were probably quite beautiful in their concept art, just not their final execution..."^[18] In addition, Kotaku's Kenneth Shepard says The Teal Mask "embodies the best and worst parts of the original game", through "The story is where The Teal Mask shines in spite of the technical troubles, so perhaps fittingly, this DLC embodies both the best and worst parts of Scarlet and Violet."^[19]

Outside of the worse performance issues (such as frame rates and graphics), the Teal Mask received generally good reception on the story and music. However, one aspect that was not present from the base game is that The Teal Mask lacked the freedom to explore the region, since there was only one story to focus on, resulting in linearity. In particular, Sports Illustrated's Ryan Woodrow shared that "There are plenty of little caves and nooks in the world of Kitakami, but they aren’t as rewarding as the ones you can find in the main game." Despite this, The Verge's Charles Pulliam-Moore claims that "...one of the most unexpectedly pleasant things about The Teal Mask is how strongly it establishes Kitakami as its own distinct space that exists within the larger world."^[20] Further, the Digital Trends' Giovanni Colantonio commented that "That [the] central story doubles down on Scarlet and Violet’s storytelling strengths by telling an endearing tale that’s custom-built for young players."^[21]
