Blue is a quirky girl whom Ash knows from his original world. Their first meeting was rather unusual; she initially intended to steal from Ash but ended up getting outsmarted by Meowth instead. This led to a series of confrontations, as Blue devised various schemes to successfully steal from Ash, including using her charm. However, she ultimately found herself consistently outmatched by Ash, and after several failures, they became good friends.
For a time, they even partnered together, but Blue eventually became fearful due to certain events in her life. She had forgotten the identities of her parents for some specific reasons, only recalling that she had been kidnapped. If it weren't for her own cunning in escaping, she might have faced terrible fates. Therefore, she began to fear that Ash might be dragged into her troubles. To prevent Ash from getting hurt, she chose to leave without saying goodbye, only to be caught and dealt a punishment by Ash later.
Afterward, the organization that had kidnapped Blue was defeated without breaking a sweat. In the face of a particularly dark adversary, the team sent to capture Blue was easily annihilated, and their hideout was obliterated by a furious father. Following this incident, Ash and Blue confirmed their relationship. However, Blue seemed to have grown somewhat rebellious and once again decided to run off on her own. This time, she did it free of burdens.
Who would have thought that her adventure would lead to trouble? Curious about a shimmering spot, she reached out to touch it, only to be sucked into a parallel world. While this place was similar to her original world, it was significantly more dangerous. Thankfully, thanks to the Pokémon Ash had trained for her protection, she managed to remain safe. However, she couldn't shake the feeling of sadness at the thought of never seeing the guy who punishes her again.
When she unexpectedly saw Ash's image reflected in a mirror, her first thought was not about calling Ash to rescue her but rather warning him to stay away from the rippling area to avoid being transported to this alternate world. She even forgot to ask Ash to come rescue her.
"I really am an idiot for not thinking to call that fool Ash to save me... Forget it... I'll just live here..."
"Roar!"
A Nidoqueen roared beside Blue, and upon hearing it, she nodded and replied, "I know, I'm okay now. Let's head to Saffron City; I hope nothing major is going on there... Why do I keep getting caught up in these messes?"
Thinking about how she had unintentionally crossed paths with Team Rocket, Blue felt like crying. Why was she always so unlucky? She knew she had to erase her data from their files; otherwise, staying safe would be impossible. However, when Blue reached Saffron City, she discovered it was completely sealed off, and the ones behind the blockade were none other than Team Rocket.
"Oh no... why is it Team Rocket?"
Looking at the city sealed off by Team Rocket, Blue felt despair. She still had things to do!
"Looks like it's sealed off? There must be something significant going on..."
Just as Blue felt helpless, a voice came from beside her, belonging to a boy accompanied by a Charizard.
"Hmm? Who are you?"
Blue stared at the boy with curiosity, but he ignored her and confidently walked toward Saffron City.
"Charizard, use Flamethrower!"
"Roar!"
Upon hearing the boy's command, Charizard unleashed a Flamethrower toward the barrier surrounding Saffron City. However, before the flames even reached the barrier, another intense flame erupted, overpowering Charizard's attack while also charging directly at it.
"Roar!"
Realizing the impending danger, Charizard quickly dodged, and the flames continued to blaze where it had just been.
"Oops, my bad, you two. No entry allowed right now."
A nonchalant voice accompanied a masked figure, who appeared before the boy and Blue, flanked by a menacing Houndoom. Smoke still wafted from the creature's mouth, confirming that it was responsible for the flames.
"Who are you?"
The boy regarded the masked man with a displeased expression, fully aware of what it meant to have his Charizard's flames countered and redirected.
The masked figure, however, ignored the boy's question and turned his attention to Blue, suddenly flashing in front of her and saying, "Oh my, a beautiful girl like you is a rare sight! May I ask for your name, young lady? I'm Sebastian, a Team Rocket executive~"
As he spoke, the masked man arrogantly lifted Blue's chin, but she instantly swatted his hand away, saying, "Sorry, I'm not interested in cocky guys, and I have a boyfriend who would be mad if he knew."
Hearing Blue's response, the masked man—the face behind the mask belonged to Ash—twitches slightly. So you know I'm capable of helping you?
But now wasn't the time for that. The performance had to stay consistent; otherwise, this girl wouldn't comprehend her boyfriend's true capabilities. So Ash smiled and responded, "Don't say that; I'm actually quite interested in a beauty like you. Of course, I'd be even happier if you'd join me for a cup of coffee."
"Not a chance!"
