Ash took the three girls to Professor Oak's lab first.
Green was going to challenge the League, so she also needed to register her identity.
After all, she had stolen her previous Pokédex, so she had to tell the professor...
Although she had used her mechanical modification skills to change the ownership to herself, there were still loopholes.
"What?! Green is the one who took Squirtle back then?" Professor Oak was shocked. He almost said the word "thief"...
However, as Tsukiko's daughter and Ayumi's older sister, he was also very aware of Green's difficult past. Instead of holding her accountable, he proactively offered his sympathy...
For a moment, Green's heart felt warm. Her past experiences had made her very susceptible to the care of elders.
Taking advantage of the free time, Ash wandered around the lab.
He found Yellow in a corner, treating a Nidoran♀.
Next to her was an anxious Nidoran♂.
As the pre-evolved forms of two powerful Pokémon, Nidoking and Nidoqueen, Ash was very fond of Nidoran♂ and Nidoran♀, so he stopped to observe.
"Don't be afraid... just a little longer and this wound will heal. Nidoran♂, you can help too~"
"Nido~"
Soon, under the green glow of her Aura, the scrape on Nidoran♀'s leg slowly healed.
And it recovered its vitality and rubbed against the worried Nidoran♂.
"Those two little guys look like they're in love!"
Yellow looked up and found that Ash was standing beside her. Her little face instantly turned bright red with nervousness.
She was the only one besides Lorelei who knew Ash's true identity...
And she had witnessed it with her own eyes last time when Celebi, the Forest God, had... given him a blowjob...
Seeing her like this, Ash couldn't help but reach out and rub her little head. "Don't be nervous. I'm really not a pervert."
"Uh... Mmm..."
The "head pat kill" was very effective. The little girl finally calmed down.
Then, at Ash's request, she gave him a tour.
This estate was a joint expansion of Professor Oak's lab and the Aether Foundation, even including a large part of the unused back mountain. So, living here was not much different from living in Viridian Forest for Yellow.
Also, she didn't have to be on guard against wild, brutal Pokémon here; she just had to focus on healing and saving lives.
She really liked this life and was very grateful to Ash.
Because the branch was built at the suggestion of Burnet and was supported by the Silver Dragon Knight, the honorary president.
She was also given the position of head of medical care for the branch.
Although she didn't have much concept of money, the little girl, who had always lived a life of poverty, was also grateful for this.
It was just that the scene of Celebi giving Ash a blowjob that she witnessed was too shocking... Coupled with the fact that she was naturally shy, she found it a little difficult to face Ash.
As they were walking, a Pikachu popped her head out of the bushes and ran to Yellow's feet, looking up at her.
From the heart-shaped tail, it was clear that this was a female Pikachu.
"Come on, do you want some Oran Berries today?" she asked with a smile, crouching down and pulling a blue berry from her pocket.
Ash watched the heartwarming scene quietly.
"Do you want to become a trainer, Yellow?" Ash suddenly asked.
Yellow looked up abruptly. "Huh?! Can I?"
Her eyes sparkled, clearly showing that she also longed for this.
"Actually... I've always envied those powerful trainers... but I don't think I can do it. I don't even have a Pokédex, and I don't know anything about Pokémon, and I..."
Before she could finish, Ash interrupted her. "No."
"You're the one who understands the hearts of Pokémon the most, aren't you?" He blinked. "Compared to the knowledge summarized by others, that's your greatest advantage."
"So, if you want to do it, just do it..."
"Pokémon... are the simplest and most lovable creatures in the world..." Ash's voice was a little ethereal. "As long as you give your heart to them, they will give their all in return."
With each of Ash's words, Yellow's eyes grew brighter.
"Okay! Then I want to become a trainer!"
But soon, the little girl became dejected again. "But I don't know how to catch a Pokémon... and I don't have a starter partner..."
"Who says you don't? Isn't it right there?" Ash pointed at the Pikachu at her feet and then took out a Luxury Ball.
"Come on, catching them is actually very simple. You just have to tell them, and they'll be willing to go inside."
Ash didn't mention battling. He knew the pure girl in front of him didn't like it.
"Then... I'll try!"
Yellow took the ball and knelt down again to rub the Pikachu who was eating her berry. "Hey, Pikachu, do you want to live with me... If you're willing, would you like to go inside here?"
"Pika~"
As expected, Pikachu didn't refuse. Her little paw happily pressed the button.
"Ding...!"
The ball didn't even shake. The capture was successful.
Yellow looked at the Luxury Ball in her hand, a little stunned. "It's that simple...?"
Ash smiled slightly. "You're the one who's so amazing~"
"Th-thank you, Ash... brother!" After a moment of hesitation, Yellow bowed to Ash.
Seeing her shy expression, Ash couldn't help but tease her. "By the way, that ball is called a Luxury Ball. It costs 300,000 Pokedollars. Remember to pay me back when you can~"
"Ah?! Th... that expensive!" Yellow's face changed.
Although she was the head of medical care, her salary wasn't much, only 20,000 a month, so... this was more than a year's worth of her salary?
The little girl immediately looked distressed. She had never spent so much money before; it was an astronomical sum.
She even started to regret catching Pikachu.
"Actually, if you promise me one thing, you won't have to pay me back. How about it?"
Ash's voice sounded. Yellow was about to agree, then she stopped... Looking at Ash's smile, she had a bad feeling.
Ah... Do I really have to eat it...?
But if I don't, I won't be able to pay it back for more than a year...
If I do eat it, can I really eat something that thick...?
Besides, does that thing even taste good?
She saw Celebi eat it so happily last time... maybe it tastes good?
For a moment, Yellow thought about many things... and forgot to answer Ash's question.
"Yellow?" Ash reached out and waved his hand in front of her.
"Ah?!... Ash, what's the condition?" The little girl immediately snapped back to reality, but her eyes were still intentionally or unintentionally staring at Ash's crotch...
Her face was flushed, making her look incredibly cute.
Ash then stated his condition. "It's just... you have to keep my other identity a secret."
"But... I..." Yellow was about to refuse, then she realized Ash wasn't talking about what she thought. She blinked her big, innocent eyes and said in disbelief, "Just... just keeping a secret?"
"Mmm... Because it's quite important to me."
Ash nodded, which made Yellow feel embarrassed.
The pure little girl's face turned red.
Why did I suddenly think of something like that... Ugh, Yellow, you really are a bad girl!
Yellow squeezed the corner of her shirt and nodded heavily. "Okay! I'll keep it a secret!"
Ash got a satisfactory answer. He looked at the cute girl and couldn't help but reach out and rub her head. His eyes held a hint of care as he knowingly asked, "Do you have any family?"
Ash's sunny and refreshing aura and his warm hand made Yellow a little captivated for a moment. The blush on her face became more pronounced. "Just... just a distant uncle in the Johto region..."
"Then... how about you become my little sister, Yellow?"
Ash had no intention of stealing Red's future wife. He just felt that such a pure and adorable girl needed someone to care for her.
She was very suitable to be a little sister.
"Huh? A stepsister?" Yellow asked innocently.
Hearing that, Ash felt a little awkward... He wondered which "sister" she meant...
But he still answered, "Uh... yeah... Are you willing, Yellow?"
Looking at his sincere eyes, Yellow narrowed her eyes and gave a brilliant smile. "Okay! I like you too, big brother Ash. From now on, I'm your stepsister~"
As she spoke, the blush on her face completely spread. She was lost in her own thoughts.
Ash didn't think too much about it. He just felt that this girl was really easy to make blush.
