Episode 01: The Birth of Arina!


After a nice visit to Kanto, Ash Ketchum, Pokemon School Student, future Pokemon Master and Runner up in the Kalos League is in Principal Oak's office chatting with both him and Professor Kukui with his friends from the Pokemon School flanking him. Ash's Rotom Dex was hovering above him.

Ash bows to Principal Oak and Professor Kukui as he smiles with Pikachu on his shoulder and space open for two more Pokeballs. He speaks up as he asked a question of the two of them. "Professor Oak, Professor Kukui thank you so much for letting me attend this school and learn more about Pokemon. The experience I've had here with my new friends and both of you have really benefited me in my quest to become the World's Greatest Pokemon Master. I would like to pose a question to you and was wondering if my friends could accompany as well."

Kiawe, Lillie, Mallow, Lana and Sophocles looked at Ash curiously wondering what he was up to. They just decided to sit back and listen.

The two Professors looked toward Ash with a questioning look in their eyes and were curious as Professor Samson Oak spoke up, "What is it you want to Exeggcute in regards to a question for the two of us?" After asking that question, Professor Samson Oak made an Exeggcute Face when he said Exeggcute, "Just ask away and we will consider an answer."

"Go ahead Ash," Professor Kukui said as he pulled out something from his pocket and smiled, "What's on your mind?"

"Well," Ash said as he cleared his throat, "I was wondering if I could go on a journey through Alola with my friends. You see, I've been used to traveling for so long, that I get kind of anxious when I'm sitting in class a lot. I was wondering if it would be okay with the two of you if I go on a journey with Lillie and the others traveling with me. I'm sure all of us can learn a lot more about Pokemon traveling Alola than we can just sitting in a classroom so often. I know it's probably not a good idea to leave the school, but I want to travel Alola and learn more and more about all kinds of different Pokemon. That is if it's okay with the two of you."

The two professors talk it over and look toward Ash and Company as Principal Oak, "I think it would be an excellent idea! Go forth and spread your wings like a Spearow!" When Principal Oak says the name Spearow, he turns his face into that of a Spearow.

Lillie and the others cheer outloud and smile as Ash looks toward the two Professors, "hey do you two have a Pokemon Transport device on school grounds? If I'm going to be traveling Alola, I will probably need two more Pokemon, right now I only Rowlet, Litten, Lycanroc, and Pikachu with me. I would like to transport two more of my Pokemon here."

Professor Kukui led Ash to a Pokemon Transport area and smiled, "here you are Ash, I will wait with the others in Principal Oaks office. Oh and I was told to give these to you by Hala and Olivia. They are Fightinium Z and Firium Z. Oh and I also have something else for you as well, here is Waterium Z in case you bring any water Pokemon here. Right now you have a Grass Type, a Fire Type, a Rock Type, and an Electric Type. Also give my best to Professor Oak in Kanto when you talk to him."

"I sure will Professor, I'll see you in a few minutes," Ash said as he dialed Professor Oaks number. Ash gets through to Professor Oak and asks for two old friends of his. Once he gets them, he hangs up the phone thanking Professor Oak and heads back to the office with his two old friends on his belt.

Eventually Ash and Pikachu return to the office and wave at everybody, "I'm back and we brought some old friends of ours. A couple of friends we didn't see when we were at Professor Oaks Lab in Kanto."

Lillie and Lana look curiously at the Ash along with Kiawe, Sophocles and Mallow as Lillie speaks up, "so Ash which two Pokemon did you get?"

Ash smiled and took two Pokeballs off of his belt and threw them in the air. In two flashes of red light Oshawott and Scraggy appear. "These are two of my Pokemon that I caught in Unova when I journeyed through there. Oshawott is a water type, and Scraggy is a dual type, Fighting and Dark."

Ash's Alola friends smile and greet the two Pokemon. The two Pokemon especially like the girls. It's apparent from the way the blush as Oshawott goes heart-eyed when he sees Steenie and Scraggy goes heart-eyed when he sees Vulpix.

Professor Kukui looks toward the group as he speaks up, "Since all of you have been through various trials on here and on Akala Island, I think it's time you kids head to UlaUla Island. Ash, you don't have to do the Electric Trial since you've already got Electrium Z. However there is a Ghost Trial South of Tapu Village at the abandoned Thrifty Mega Mart. There is also a Grand Trial on UlaUla Island. I wish all of you kids the best of luck. Also be careful of the winds, there have been reports of different Pollen from the various flowers in Alola combining and affect individuals differently. Best of luck and I look forward to hearing of your adventures in the rest of Alola." Professor Kukui then had an idea, "before you all go to UlaUla Island, how about you explore more of this Island and the rest of Akala Island. There is still a lot to do on both Islands. Go, explore both Islands, once you've thoroughly explored Melemele Island and Akala Island, let me know and I will take you to UlaUla Island." Right before Ash and Company left on their adventure, Professor Kukui presented Lana, Lillie, Mallow, Ash, Kiawe and Sophocles with Z-Power Wings and gave Ash Lycanium Z. "Also, I'm going to suggest you go to Ten Carat Hill as well. There is a piece of Flyinium Z in there, but you can wait until later to do that."

Ash and Company nodded as and headed into Hau'oli City with backpacks and bags. Rotom Dex was hovering above the group as always as they began to explore Hau'oli City. Of Course the girls went straight for the shopping district. Ash decided he would go with Lillie, Lana, and Mallow for a bit as Kiawe and Sophocles decided to explore Hau'oli City and the Beach Front as well.

Ash really enjoyed shopping with the girls surprisingly. He even picked up a few rare items as well and watched a Pokemon show. This journey was definitely going to be a lot of fun! Traveling Alola with his friends from Pokemon School, and wondering if he would meet up with Misty and Brock again as well as some of his other friends.

Ash let Lillie, Lana, and Mallow know that he was going to explore the town some more. He may even visit Illma again just to see how he's doing. As he stepped outside with Pikachu in his usual spot on his shoulder, several flower petals of different colors blew in the wind. Their pollen and nectar blowing right into his nose. Red petals from UlaUla Island, yellow petals from MeleMele Island, pink petals from Akala Island, as well as purple petals from Pony Island. The pollen from those flowers were breathed in by Ash as he sneezed profusely and shuttered in pain as his body hair, or the little body hair he had suddenly disappeared.

"What's happening to me?" Ash asked no one in particular as he headed toward the Pokemon Center to lay down for a bit, "Nurse Joy, could I have a room for the night? I have five more friends that will be checking in as well. I would prefer my own room please."

"Sure thing Ash," Nurse Joy said with a smile as she handed Ash a card key. Ash thanked Nurse Joy and immediately went upstairs, laid down on his bed in his Pokemon Center room and fell asleep. Subtle changes happened to Ash over night as he lost some muscle and his legs got a bit longer along with his torso.

Later that night, Lillie and the others arrived at the Pokemon Center and checked in. Once they checked in they went to their rooms.


The next day everyone woke up to a beautiful Sunrise outside their windows. Ash woke up feeling a bit light-headed. "What's going on?" Ash asked curiously as he got up and looked in the mirror. He noticed that his hair was slightly lighter and had reached down below his shoulders. It wasn't as messy as it usually is in the morning. He also noticed that his legs got longer and his fingernails had lengthened some. His toenails had also gotten longer as well. "I look, different. Also why does my stomach hurt?" Ash then looked at his waist and hips and notice that his hips have flared out overnight and his waist had caved in. "I need to see if Nurse Joy knows what's happening to me."

Ash stumbled down the stairs not used to his new hips as he heads toward the counter, "Nurse Joy, I know you don't really deal with people, but I've been feeling lightheaded and strange since before I came here yesterday. Also, a lot of things have changed about me overnight. Look at the hair on my head and my smooth arms other parts of my body have been losing muscle as well. My chest has started to hurt too. Look at my waist and hips." Ash can't get much farther as he faints.

Lillie and the others come downstairs and see Ash pass out as his face begins to change and his eyelashes lengthen and his eyes get bigger as his face lose his angularity.

"We need to get him to the hospital, I sense something is doing this to him, soon he will look completely different," Nurse Joy said, "I can't deal with humans here. We have to get him to the hospital."

Lillie looked toward Nurse Joy worried, "What do you mean he will look completely different? What's happening to him?"

Mallow then remembered something, "hey didn't Professor Kukui mention something about the combination of Pollen from all the flowers in Alola? All four of those flowers released their pollen and apparently Ash breathed it in. Since Ash is from Kanto, the pollen has more adverse effect on Ash. I've heard about that. Something is changing his DNA into something different, but his soul will remain intact. He's turning into a girl."

"What?!" Lana asked surprised, "How in the world can the pollen affect Ash that way? Something is definitely off about that. Something or someone had to modify it somehow."

"I really hope we can still be friends with her." Kiawe said worriedly.

"I wouldn't worry about it too much, Ash will still be Ash even as a girl," Sophocles said believing in his friend, "Though I can't help but wonder if she will start spending a ton of time primping and stuff."

"I hope she will still be the same Ash we all know and love even though she will be a girl," Lana said worriedly, then continued, "We will have to take her shopping!"

Lillie and Mallow smiled as they pondered what embarrassing outfits to put her into. This was going to be fun.

Kiawe, Lana, Lillie, Mallow, and Sophocles stayed at the hospital and took turns going into see Ash. Each time they went in they noticed some subtle changes in him. They now knew what was happening to their friend. Pikachu was at Ash's side all the time.


The next morning Ash got up a lot earlier than usual and headed to the bathroom that was inside of his room. As he woke up he felt his hair touching even lower than below the shoulders yesterday. When he went into the bathroom he immediately saw a purple ribbon and a brush in the cabinet above his sink. He was still in his hospital gown. Deciding he better clean up, he stripped down to his boxers and undressed to get into the shower, he seemed to be okay and is able to walk a lot easier and not stumble. He figured it was probably just a temporary thing as he stepped into the shower.

As the water cascaded down his now longer hair, he sighed, "This water feels so good. I still don't understand why this happened to me though." Ash looks down at his flared out hips and noticed something else as he looked behind him, his rear end had been lifted and gotten a bit more fleshy since yesterday. "Why does my tail bone and rear-end look fuller now? It's almost as if it's a girls rear." Figuring this was nothing but a dream, he brushed seeing his body this way as just a hallucination. Little did he know that it wasn't a hallucination, not at all. Ash was released without restrictions later that day as he smiled and waved good bye to the hospital staff and continued his Alolan Journey with his friends from the Pokemon school.

Ash and Company had a nice Lunch in the Hospital Cafeteria before they continued their journey of exploration through Alola.


As our heroes traveled through Alola, Lycanroc learned the move Stone Edge and was able to pull off a perfect Splintered Storm Shards Z-Move. Surprising to Ash the Terrain effects were negated by said Z-Move. As their journey progressed, Ash's changes became more evident. He was turning into a very beautiful girl. His face was feminine as well as his hair. He decided to put the purple ribbon in his hair after all. Each day Ash's hair got lighter and longer. It got to the point that Ash could no longer hide his hair in his cap, so he gave his Alola Cap to Pikachu to wear. Pikachu also finally learned 10,000,000 Volt Thunderbolt Z-Move. Oshawott and Scraggy learned to pull off the Z-Moves Hydro Vortex and All Out Pummeling respectively. Everyone, even Lillie tried out Mantine Surfing and enjoyed it. Lana was the one that enjoyed it the most since she loves water Pokemon so much. Surprisingly Lillie was given Icium Z for her Z-Power Ring and Snowy successfully learned Sub-Zero Slammer. Togedemaru learned to pull off Gigavolt Havoc as well. Ash and Company were enjoying the scenery when Ash collapsed to his knees. the final stage of his Transformation was happening as his hair went as blond as Lillie's and stopped at waist-length.

Ash grabbed his stomach and his chest as they were both in intense pain as his reproductive organs change into their female counterpart and his manhood became her womanhood. A pair of C-Cup breasts pushed out from his now her chests as her lips became fuller and her eyelashes finished their complete growth. Not only that, when Ash started to talk, his voice had completely change to a girls voice. She had to tighten her pants while she was on her knees and had to rearrange her boxers to make them more comfortable. When she got up she started walking back toward the group as her chest bounced distracting the boys, more specifically Kiawe.

"My back so hurts now! I think I need to get some new clothes," Female Ash said as she walked back toward the group. With her new plumbing and body shape she had to sway her hips now to be able to walk comfortably. Lillie looked at the now female Ash and squealed, she looked so cute. She also looked to be about the same size as her and Mallow are.

"Hey Ash," Lillie said with a smile, "how about Mallow and I lend you some of our clothes. You look to be our size."

"I don't know," Female Ash said as she shivered, "me in girls clothes? I don't know if it will work."

"Why not?" Mallow asked Curiously, "It's obvious your a girl now. You need some more supporting clothes and no more sleeping with the boys."

"Why not?" Female Ash asked worriedly, "I'm still the same person inside."

"True," Lana said then continued, "but now your physically female in every sense of the word. I think you will probably need a different name too."

Rotom-Dex looked at Female Ash and had hearts in its eyes, "You are so beautiful! It also looks like Pikachu is just as attached to you as ever. I think your other Pokemon will be the same way."

Female Ash blushes and smiles, "Th-thank you Rotom I appreciate it." Ash looks toward Lana, Lillie, and Mallow as she speaks up, "I have to admit though, I really need some more comfortable clothes."

The girls giggled as they dragged and pushed the new girl to the nearest apparel shop.

"G-Guys I can walk by myself. You don't have to push and drag me," Ash said nervously as she was feeling really uncomfortable on two fronts right now, her clothes and how her friends are literally dragging and pushing her all over the place. "This is really going to take some getting used to."


Ash and her Comrades are in Gracidea after buying some essentials from the normal MeleMele Apparel shop and styling her hair at the MeleMele Hair Salon. Her now blond hair is down to her waist and is styled in a straight pattern her bangs are still the same or nearly the same as they were when she was male. Ash was stunned by the prices of everything in Gracidea. "We really can't afford this stuff right now. It's so expensive."

Lillie giggled and smiled, "I can afford this stuff easily come on Ash, let's look around, I'll buy the stuff for you."

Lana and Mallow started looking around and decided to help Lillie look while Ash took the clothes that Lillie offered her and the essentials they bought for her and went into the restroom to change. Pikachu and Rotom Dex waited outside the girl's restroom for Ash to get dressed.

Ash came out in more comfortable clothes she was wearing a White T-Shirt, white skirt, white knee-high stockings that Lillie gave to her as well as her normal shoes. Sure Ash had to tighten her tennis shoes as tight as she could with her new smaller feet, but it really was a good thing that they are the same size clothing wise now. Pikachu and Rotom were struck in awe by how pretty Ash actually was. There was no trace of the guy she once was, but her heart and soul were the same as they've always been. Pikachu happily jumps up to Ash's shoulder with Rotom-Dex hovering above her as always. Under her outfit she had a pair of panties, but she's not wearing the bra because she doesn't know how to put it on yet. As Ash walks, her hips sway and chest jiggles.


Later on Ash and Company along with Kiawe and Sophocles are eating at a restaurant in the mall. "Hey Ash," Lillie said, "I can tell you aren't wearing a bra because your chest is jiggling. You really have to put one of the bras that Mallow and I gave you. Your back will thank you for it later."

Ash looks at Lillie as she sighs, "Well I would, except for one thing, I have no idea how to put a bra on. It hurts like heck when I walk and they jiggle. I need all three of you to take me into the restroom again and teach me o put on a bra."

Lana and Mallow squeal as they giggle. This is going to be really fun. Lana speaks up, "meet the three of us in the Women's restroom, we will help you them. We've got all the time in the world to teach you how to put a bra on, but first things first, we really need to think of a new name for you."

Ash ponders what Lana was saying, she really couldn't go around being called Ash now that she was female could she? Should she go by Ashley? No Ashley is way to common. What would her mother have named her if she had been born a girl though? The question enter her mind as her Rotom Dex Rings.*

"Ash," Rotom Dex said, "it's kind of odd considering how far away from Kanto you are. It's time to face the music Ash, you have to change your name. There is no way around it now."

Ash sighs as she shrugs, "I guess you're right Rotom, I have to come up with a new name. I'll see what Mom thinks I should be called."

"That a girl Ash," Rotom said with a smile, "I will send you through with voice only at first." Ash smiles and hugs her Rotom dex causing him to blush.

"Mom, are you there, I have something to show you, I look really different now," Ash said to his mom via voice, surprisingly she hears her mom giggle. "Mom what are you giggling about?"

"Professor Kukui and Principal Oak told me what happened," Deliah said with a smile in her voice, "I've know for the past few days that you were a girl now. As far as we know there is no cure, so we changed your Birth Certificate to show the change in your Gender. I always knew something was special about you. You never seemed to be too in to any of the shoot-em-up type of things, but you've always loved Pokemon. So the different pollen did a number on your body and DNA huh?"

"Yes Mom," Ash said with nervousness in her voice hoping to Arceus that her own mother wouldn't Dis-Own her, she then continued, "Lana, Lillie and Mallow said I need a different name. I was wondering if you had any ideas what my name would be if I had been born an actual girl rather than to get transformed into one. If I were born a girl, what would you have named me?"

Delia smiles as she speaks up, "I'll only tell you on one condition."

"What condition is that Mom?" Ash asked curiously still having the function on Voice only, "please let me know."

"I want to see what you look like now," Delia said with a smile in her voice, "either have Rotom take a picture of you and send it to me, or turn off voice only and show me what my beautiful daughter looks like now."

Ash couldn't help but blush as she heard her mom call her a beautiful daughter, "Okay Mom, you win I will turn on video chat now."

When Ash turned on video chat, Delia couldn't believe her eyes, staring back at her was a beautiful girl that was once her handsome son. Her face was done up nice and beautiful with just a little bit of make up to highlight her natural beauty. Her long straight blond hair was nicely completed with a purple Bow in it. She then remember what she would've named Ash if he was actually born a girl. Now her dream of having a daughter came true. It was right then and there that she spoke up.

"Arina, honey," Delia said with a smile confusing Ash to no end, seeing the look of confusion on her beautiful daughter's face she continued, "if you were born a girl I would have named you Arina Ashley Ketchum, now that you are one, that's what your name will be from now on. Arina Ashley Ketchum future Pokemon Master. Arina is the name I would've chosen had you been born a girl. Now that you are a girl, you're full name is Arina Ashley Ketchum. It suits you perfectly."

The newly named Arina pondered her new name a moment, it struck a cord with her, she really liked that name. It seemed that Pikachu and Rotom-Dex agreed. From here on out her name will be Arina Ashley Ketchum.

"Arina Ashley," Arina said with a smile, "I really love that name, I don't know what it actually means, but it has a beautiful ring to it. Thank you Mom, I really like the name Arina. Could you let Professor Oak know?"

"I will do that honey, take care of all your friends and change you're you know what everyday," Delia said immediately embarrassing her daughter, "I love you my dear Arina."

Arina blushed out of embarrassment, but smiled back at her mom as she spoke up, "I love you too Mom! I will take very good care of my friends and Pokemon like I've always done. Talk to you later Mom."

"Talk to you later sweetie," Delia said as she ended her call, the newly named Arina also ended her call. Arina then turned to her friends and smiled.

"It's official, my full name is now Arina Ashley Ketchum. Please call me Arina," the newly named Arina said with a smile toward her friends.


Lana and Lillie took Arina by the hand and dragged her into the women's bathroom with Mallow close behind Pikachu and Rotom-Dex stood guard outside the restroom door. The three girls took her to the biggest stall in the Women's restroom, which was big enough to hold all four of them. The girls showed Arina how to put on a bra several times over until Arina finally got it right. It only took her about five times, probably because she has had experience Cross-Dressing in other regions throughout her journey.

Lana, Lillie, and Mallow handed Arina a stack of clothes sandals, and bag that they had pooled their money for. The also handed her a necklace with a blue and white chain attached to a blue and white pendant. The clothing consisted of a white V-Neck tank top blouse similar to Dawn's black one, a blue camisole to cover up her bra and cleavage, a blue and white vest with white top section and a blue lower section with white pockets. A pair of blue and whit forearm/elbow bands, and blue, black, and white fingerless gloves. A blue shoulder bag with a blue Satchel that has the shape of a white Pokeball engraved on. The ensemble is completed with a skirt just like Dawn's normal outfit, but of a white color and a pair of low-heeled sandals.

"Put these clothes on and we can continue our MeleMele Island Adventure," Lillie suggested as her, Lana and Mallow left the bathroom stall to allow Arina to get dressed.

As soon as she was done getting changed, Arina put Lillie's clothes in her new bag and exited the restroom. Upon exiting, Pikachu happily hopped up on Arina's right shoulder and Rotom Dex hovered above them like always.

With that Arina and Company headed to the Malasada Shop to meet Kiawe and Sophocles.
