Lana 'Opunui

Hokuhelele'i Lana 'Opunui is from Hau'oli City on Melemele Island in the Alola region. She's traveling with the Mokusetsu through Paniola Town as they look for Hi no Tama, the Fire Plate. She's the older sister of Harper and Sarah 'Opunui.

Background
The 'Opunui family was already mildly struggling financially, but Lana's parents figured they can afford the expected child, since the wife was pregnant. However, after further tests, it was revealed that Lana's mom was having twins. This shocked her parents and kept them uneasy. The twins were born and Lana loved them dearly. She enjoyed playing with them and was a major part of their early infant days.

When the twins were 2 and Lana was 12, however, it was ultimately decided that Lana's parents couldn't afford 3 children instead of 2. They gave up the twins to a foster home. Lana was furious at this and had begged them for weeks not to do this. When it was done, Lana was extremely upset at her parents and couldn't find it in her heart to forgive them. Alola doesn't have a foster home, so the twins were sent to a different region. Knowing the foster home system, when one home can't maintain a certain capacity, children might be sent to a different home at sporadic times. Lana had no idea where the twins were.

Lana was highly upset at her parents for a long time. She ended up wanting to move out. She talked to her best friend at the time, Mallow, who allowed her to move with her to the apartment of her older brother, 'Ulu, who had recently gotten the apartment since he was 18. It worked out and Lana has been living with Mallow and her brother for 7 years by the time the series starts. Lana rarely visits her parents.

Present
Lana officially debuted in Episode 30. She's one of the few students of Professor Kukui's Alolan summer academy, along with Mallow, Kiawe, and Lillie. This academy isn't official; it's meant for more specialized knowledge that can only be learned in Alola. It was Kukui's idea and since participation isn't certified, student numbers remain low.

Lana was in the classroom in Hau'oli City when Alain, Ash, and Dawn arrived there to recruit people to the Mokusetsu while they look for the two Plates in Alola. Neither Lana nor her classmates knew who they were at first and thought they were new students, until Kukui informed them about their mission. Lana introduced herself to them. For some reason, probably due to her mainly ocean blue attire and wave pattern on her pants, she's erroneously referred to as a mermaid by Alain. Regardless, she's generally cheerful and is happy to be a part of the academy. After Kiawe and Mallow decide to go with the Mokusetsu to help get the Fire Plate, Hi no Tama, she does the same, followed by Lillie.

In Episode 31, Lana traveled with Division A of the Mokusetsu through Hau'oli City. Alain kept referring to Lana as a mermaid, despite repeated times that Lana said she isn't one. Later, also overlapping in Episode 32, Lana told them about herself, including mentioning that she lives with Mallow. She mentioned that this is because when her parents gave away her twin sisters to a foster home, she was angry at them because she wanted to see her sisters. Since Alola doesn't have a foster home, she didn't know what region they were in. She ended up running away from home and living with Mallow and her older brother, 'Ulu, in his apartment. She told them she's been living there with them for 7 years.

In Episode 33, upon arriving in Paniola Town with the Mokusetsu, she and everyone visited Kiawe's family, Sima, Rango, and Mimo. After this, they went to a different area to search for Hi no Tama, but to no luck. Lana was searching with Lillie. Ash came and joined them, reporting no luck either. Lana declares she notices something that's "interesting", but wouldn't say what it was. She left to search somewhere else, leaving Ash and Lillie to search on their own. Lana later hid when Alain announced that people were approaching. This turned out to be Tupp, Rapp, and Zipp, former Team Skull members now with the Tekiyoku. She watched as a fight began.

The fight happened in Episode 34. Lana watched as Ash fought Zipp, Kiawe fought Tupp, and Alain fought Rapp. She was nervous watching this. Dawn told her these fights get easier to watch after a few of them. The showdown ended with the Mokusetsu victorious and the former Team Skull enemies retreating.

After this, Lana and the others continued searching for Hi no Tama. The search went for a while with no luck and a scorching sun overhead, due to the drought. Lana was with Dawn during this. She was impressed with how Dawn can see those intense battles with the Tekiyoku. Dawn says Ash always guarantees that everything will be all right, and that always eases her nerves. Lana mentions that Lillie has changed, too, and is speaking more and is somewhat more happy. She says this is likely due to Ash, while saying she noticed that Lillie is feeling closer to him.

More searching happened next. Eventually, Ash took Alain's Charizard to the top of a nearby silo. When he came down, he had the Fire Plate, which was hidden in a barely visible layer at the top of the silo. This brought about rainfall in the area, effectively ending the drought. Lana, along with the others, congratulated Ash. After this, it was decided that Lana, Mallow, and Kiawe would keep traveling with the Mokusetsu for the last Plate in Alola, since Lillie doesn't want to leave them until Gladion is brought back to her. She stayed with everyone as they went back to Hau'oli City that night to stay with Lillie, who volunteered for them to stay at her house. At Lillie's house, the decision is made to wait a few days before seeking Ganseki, the Rock Plate, there in Hau'oli City.

In Episode 36, Lana's with everyone as they trek through the city the next day. Division B (Barry, Zoey, Kenny, and Bianca) ends up video-calling them in a Pokémon Center. Here, Lillie tells Lana, Mallow, and Kiawe that she's okay with her "Silver Moon" moniker returning, making them happy. The evening comes, where a big talk happens with everyone where a lot is revealed. It ends with Lana, Mallow, and Lillie learning that Kiawe wants to join another organization of fighters against the Tekiyoku called eXpulsion. They're shocked at first, but end up supporting Kiawe with whatever decision he ends up making.
