This Eevee, nicknamed Marin or Nagisa, is a -type Pokémon owned by Lana, who stars Where is Eevee Going? mini-segments, and eventually made his proper main series debut in Pokémon the Series: Sun & Moon - Ultra Adventures in the episode SM099.

Personality
Since his debut, Nagisa is curious, naive and upbeat, frequently greeting others around him amiably or sniffing in an inquisitive manner, but he can also come off as inconsiderate, such as unintentionally scaring a Wimpod while chasing it and causing a Pyukumuku to punch him away. He is also quite gluttonous as he always gets exhilarated upon seeing any type of food.

Thanks to his past experiences with Mantine, Nagisa himself became an expert swimmer which evenly matches his best friend and teammate Brionne. Also, Nagisa loves the ocean as he loves to swim, play in the water and Matine Surfing in it, especially doing those activities with Brionne and Lana.

Nagisa cares deeply for his friends and would go out of his way for them, shown when his close friend Mantine with other Mantine were captured by Team Rocket. Much like Brionne as Popplio, Nagisa was also saved from Team Skull by Lana as he took an instant liking to her for her kind act. Also, Nagisa is very close and loyal to Lana. In addition, Nagisa is close with his trainer family, especially Harper and Sarah.

Biography
Once a nameless Eevee, Nagisa was walking along happily by the docks until he got hungry eyeing a bowl of food. Nagisa started eating until a Houndour appeared angry at the Evolution Pokémon for eating its food and was soon chased by the Houndour, after failing to make amends with it. Managing to lose the Darkness Pokémon in a crowd of people Nagisa found himself on a boat, brushing his bangs away from his eyes he marveled at the view of the big blue ocean.

When a Wailord shaking the ship reveals where Nagisa is, Nagisa is revealed to be sleeping inside one of crates, which fell into the sea. Once he wakes up, Nagisa begins to panic and is about to drown after falling from the now sinking crate he was in, but is rescued by a Mantine, who soon takes Nagisa to a safer destination. As he and Mantine are almost near the land, they had a little fun doing a stunt on the medium wave, where they happens to passed by the boat where Lana’s father is, who witnessed them.

Although only Nagisa, Pikachu, Sophocles' Togedemaru and Kiawe's Marowak got hit instead, just as the Alolan Marowak scolds Nagisa about touching Turtonator’s explosive spikes, it cut short when Nagisa, Marowak and their friends noticed in laughter that Pikachu revealed to only have head-burn instead of full body burn.

While looking through town, Nagisa saw Popplio in the arms of her trainer, Lana, then followed them into the store they were going to. Nagisa greeted a Persian, who has caused some trouble for Ash and his friends in the past, believing to be a new friend but soon realizes that its not his friend then ran away. Nagisa, who is hiding from the Persian, was dragged by Popplio, who saw him being chased and left her trainer to help him, which made him happy to see one of his new friends again. However, Nagisa unknowingly left his tail open in the bush they were hiding in which the Persian noticed.

Trivia

 * Although it wasn't told, it was quickly revealed that this Eevee, Nagisa is a male, not just his early hairstyle and upbeat personality, due to mostly ever since Eevee species’ late gender differences reveal on the tip of their tail in Pokémon Let's Go Pikachu and Let's Go Eevee.
 * Before his actual capture, a promotional poster and the first opening theme featuring Nagisa strongly implied that he was to be captured by Ash Ketchum due to Nagisa being seen in both shots near the trainer.
 * The poster was later updated just to reflect on his new hairstyle, but he's still next to Ash.
 * Nagisa is similar to the human main characters Serena and Lillie such as receiving newer hairstyles in certain episodes onwards.
 * Nagisa being owned by Lana was foreshadowed by his past experience with Mantine.
 * Nagisa and Snowy are the only main nicknamed Pokémon in Sun & Moon.
 * The name Nagisa means calm beach in Japanese.
 * Nagisa is the first Pokemon to be caught in a Dive Ball in the anime.
 * His capture also marks the longest duration between one of Ash's female friends' first and second captures, taking a 99 episode gap.
 * Nagisa can be somewhat similar to Ash's Totodile, in term of being both upbeat Pokémon who are caught in special Poké Ball respectively, and even closely relating to any sort of -type related from their either encounters and their trainers who has one of them.
 * Nagisa can be also a polar opposite to Ash's Scraggy, due to both always greet with certain attacks (Tackle and Headbutt respectively) rudely, but their traits are different, whereas Scraggy is very intimidating on purpose, while Nagisa is very affectionately naive but unknowing to him rude.
 * Nagisa is the third Eeveelotion to be caught by a traveling companion of Ash's. However, he is so far the only one of them to have not evolved.
