Lillie Hidaka

Lillie Ke'alohi Hidaka 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 little sister of Gladion Hidaka and the daughter of Lusamine Hidaka and Mohn Hidaka.

Background
Lillie grew up in Hau'oli City with her mother, Lusamine, her father, Mohn, and her big brother, Gladion. Lillie wasn't well-liked when she was younger and would get picked on occasionally as a result. Gladion would defend her, though, and protected her. She always felt better around him and depended on him heavily when she needed guidance. They were close as brother and sister.

As years went by, however, she started noticing Gladion acting differently. He became involved with the wrong crowd and even befriended some members of Team Skull at the time. She started to worry about him, but didn't directly confront him about this.

When Lillie was 12, one night, she noticed Gladion with packed bags, sneaking out of the house. She asked him what he was doing. He replied that he was joining the Tekiyoku. He wouldn't tell her why, though. She started begging him to stay, pleading with him desperately. He didn't listen, however, and he left anyway. Lillie cried deeply. She eventually told her mother and father the next day. They all kept living their lives, but Lillie missed Gladion immensely.

Over 2 years later, Hau'oli City was being terrorized by some Tekiyoku members. Part of this was taking place in Lillie's neighborhood; she was 15 at the time. Lillie's mother, Lusamine, was at work during this. Lillie's father, Mohn, ran out to stop some of the Tekiyoku. The enemies ended up beating him up, prompting Lillie to run out there as well. She pleaded with them to stop. Suddenly, she heard a voice telling them to move aside. It was Gladion. This was Lillie's first time seeing him since he left. She asked him questions, but he ignored her. He approached the enemies who were around his father. He then killed his father right in front of Lillie's eyes. Lillie was speechless at first and then cried over her father's dead body, as Gladion and the enemies left the area. Lillie hasn't seen Gladion since.

Some time after this, both Lillie and Lusamine have managed to forgive Gladion and want him to return home.

Pre-Series
Lillie was first seen in the Transmissions. She appeared in Transmission #7 along with several other citizens of the Pokémon World. They all expressed their complaints about how the Tekiyoku is changing everything, ending their beloved traditions, and making their lives terrible.

Present
Lillie officially debuted in Episode 30. She's one of the few students of Professor Kukui's Alolan summer academy, along with Mallow, Lana, and Kiawe. 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.

Lillie herself is generally quiet when introducing herself to Alain, Ash, and Dawn, who were at the academy to recruit people to the Mokusetsu while they look for the two Plates in Alola. Neither Lillie nor her classmates knew who they were at first and thought they were new students, until Kukui informed them about their mission. Lillie stays quiet and doesn't add much to the conversation that follows. She does agree to come with the Mokusetsu for their Alolan journey to help get the Fire Plate, Hi no Tama, while the other students agreed to come as well.

In Episode 31, Lillie travels with Division A of the Mokusetsu through Hau'oli City. She gets called "Blondie" by Alain more, which was first done in the previous episode. Lillie remains generally quiet, prompting Alain to ask her if she's shy. She says that she's not, but still nervously stammers when asked questions. Right before the group got to a clearing to tell each other more about themselves, Alain asks Lillie if he knows her, saying she looks familiar. Lillie nervously says she doesn't think so.

Lillie was the last person being awaited on to tell the others about herself. She stammers again, and then suddenly runs off. She runs a small distance into the nearby forest. She's approached by Ash and Alain. Alain confirms Lillie's name and then says he thinks he knows who Lillie really is. He asks her to tell them about herself again, warning her not to lie to him. Lillie remains nervous and begins to tell them.

Continuing in Episode 32, Lillie explained that her brother's name is Gladion Hidaka and that he's a member of the Tekiyoku. This shocked Ash and confirmed Alain's suspicions. Alain was angry at her for hiding this at first. Lillie was about to be abandoned by the Mokusetsu since Alain didn't want to travel with a Tekiyoku member's relative, but Ash did not want that to happen. Lillie then expressed that she had a request. She wanted them to bring Gladion back to her family. Alain asked if she still wanted him back after "what happened". Ash didn't know what he was referring to, but he assured Lillie that she didn't have to tell him what it was until she was ready.

Back with everyone else, Kiawe, Mallow, and Lana have already told Dawn the information about Lillie, including the extra detail she hasn't told Ash yet. Lillie's friends back her up and are determined to stay with her, whether she can travel with the Mokusetsu or not. Alain ends up letting her travel, but warns her not to do anything suspicious. Ash assures her that they'll bring her brother back, which cheers her up.

Lillie's at a gathering with all the girls later that night after training. She listens to the stories told and watches Dawn cheer up Mallow and Lana about their situations. Lillie suddenly feels differently and sadly declares she needs to take a walk.

She's later approached by Ash. Ash says they don't have to talk and they can just watch the stars. Lillie does this at first, but then decides to tell him the rest of the details about her past anyway. She tells him about the part that's outlined in the Background section about Gladion and how he left the family to join the Tekiyoku. She then mentions the day that he returned, but ignored her and then killed her father in front of her. She then asked a stunned Ash to not say anything as she cried, and pleaded with him to bring Gladion back to her and her mother, saying they've forgiven him.

In Episode 33, as the Mokusetsu left their camping area that next morning, Lillie was still pretty quiet and melancholy. Ash happily nominated her to be the tour guide for them to see more of Alola after they get this next Plate. She accepted and was cheered up at this. Upon arriving in Paniola Town later, Lillie was there as the group visited Kiawe's family, Sima, Rango, and Mimo. After this, they went to another area of the town to search for Hi no Tama.

During this, Lillie was searching with Lana and was still pretty quiet. They had no luck finding the Plate. Ash then joined the group and said he didn't have any luck either. Lillie suddenly was more talkative and assured them they'll find the Plate if they keep trying. Lana said she noticed something "interesting" and left Lillie with Ash as they continued searching. Here, Lillie admitted to Ash that she didn't have a Pokémon, due to no one ever taking her to get one and her family not exactly approving of Pokémon battles. Ash promised to take her to get one of her choice later after the world is saved. Lillie picked Eevee to be this Pokémon and was very happy that Ash would do this for her.

Following this, enemies approached the group as Lillie hid with everyone except Ash, Alain, and Kiawe, who were set to fight. The enemy turned out to be Tupp, Rapp, and Zipp, 3 former Team Skull members who were now with the Tekiyoku. Lillie watched as a fight began.

The fight happened in Episode 34. Lillie watched as Ash fought Zipp, Kiawe fought Tupp, and Alain fought Rapp. Lillie was amazed at the inensity of the battle. The showdown ended with the Mokusetsu victorious and the former Team Skull enemies retreating.

After this, Lillie 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. Lillie was with Mallow, when Ash came up to them. Lillie expressed concern to him, asking if he was okay, which Ash confirmed. He motivated them to keep pushing forward, prompting Mallow to echo this energy.

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. Lillie, along with the others, congratulated Ash.

Discussions were made for Lillie and the other Alolan citizens to leave the Mokusetsu and go back to Kukui's academy. The others were onboard with this, with the intent to return later and become Manipulators. However, Lillie nervously said she didn't want to leave. This caused a silence in the others. Lillie shouted that she didn't want to stop traveling with the Mokusetsu until they brought Gladion back to her. Ash broke the silence by ensuring Lillie they'd bring Gladion back to her. Kiawe, Mallow, and Lana followed suit and decided to keep traveling with Lillie and the Mokusetsu for the last Plate in Alola. This made Lilllie happy.

In Episode 35, as everyone was preparing to go back to Melemele Island to find somewhere to stay for the night, Lillie volunteered her house since it's large enough to accommodate everyone. Everyone then boarded a ferry to go back to Hau'oli City. Upon getting there, Lillie video-called Lusamine, her mother, but was told she wouldn't be home that night, but that she insisted on Lillie having everyone stay over for the night anyway. Lillie told this to everyone else after the call and was upset at this, since she doesn't know how to host a night with friends staying over on her own. After the group split to explore the downtown area on their own later, Lillie was with Mallow and Ash. Dawn and Lana came to them to join. Ash said he wanted to go sightseeing with Pikachu, but Dawn said she wanted to come with him, too. Lillie reacted to this, seemingly worried that Ash and Dawn would be walking alone together, but Mallow interrupted before she could say much, and she, Lillie, and Lana left to explore on their own. Prior to this, Lillie already made sure everyone had her address.

Later that night, everyone else eventually made it to her house. Lillie went over things like sleeping arrangements, even being okay with them using Gladion's bedroom as a guest room as well. The night continued as normal. Late in the night while everyone was asleep, Lillie quietly approached Ash's bed while he was asleep. She woke him up and looked at him with a nervous expression. She said she needed to talk to him outside to make sure no one else could hear. They started walking outside to find a spot to speak.

This continued in Episode 36, where Lillie told Ash she had trouble sleeping because she was thinking of her brother. She mentioned how it's strange how he joined the Tekiyoku since Gladion was always someone who exuded positivity and seemed to "light up" areas around him. Because of this, people used to call Gladion the "Golden Sun". In addition, due to Lillie's personality being sort of an opposite of Gladion's, but since the two complemented each other so well, she was called the "Silver Moon". Her friends haven't been calling her that lately because of the bad memories surrounding Gladion. But after talking about this with Ash, she started to feel better about having that moniker for her again. Ash expressed that he didn't wish for Gladion to return back to Lillie and her mom so soon since there's a chance he could try to kill them as well. He said that before anything is decided, he'll try to talk to Gladion himself. Lillie's grateful at this and is a little surprised Ash would be this worried about her. After feeling better, Ash reminds her that she was nominated to be a tour guide for Division A and that she should do this tomorrow. They end the conversation and Lillie goes back to sleep.

The next day has Lillie nervous when it's finally time to be the tour guide, comedically pointing out random things. Some time after this, they gather in a Pokémon Center, where they have a video call with Lillie's mom, Lusamine, who approves of everything they're doing, but can't come home just yet. Division B (Barry, Zoey, Kenny, and Bianca) checks in with them after this, with her explaining how her mom used to be an attorney but is now the owner of a marketing company, making Lusamine travel frequently. Lillie ends up telling Kiawe, Mallow, and Lana that she's okay with her Silver Moon nickname returning, making them happy, although Alain says he'll stick to "Blondie". Outside, Lillie expresses gratitude to Ash for helping her to feel better, but the two aren't sure what to do next for locating Gladion. Later that evening, Lillie's there with everyone as many things are revealed, including details about the organization known as eXpulsion and that Kiawe wishes to join. Lillie and the others end up supporting whatever decision Kiawe wishes to make.

Naming

 * Her first name, Lillie, is her name in the English dub of the Pokémon anime. It's an alternate spelling of her Japanese name, Lilie, which is German for lily.
 * Her middle name, Ke'alohi, was randomly selected from a Hawaiian name generator. Hawaii was chosen for the name generator, due to her region, Alola, being based on Hawaii.
 * Her last name, Hidaka, was selected for her by Nocturnal Jay. It roughly translates to "high sun in the sky".

General

 * Her birthday, December 22nd, is the original Japan air date for Episode 8 of Sun and Moon. This episode was chosen because it's the first episode where Lillie blushes towards Ash. Jay and his friends would like for this to be AureliaShipping Day, but at the time of writing, there's no official day for this.
