Within a district called Old Downtown, Valen saunters down a cobblestone plaza walkaway, as there's no roads that pass through this part of Angel City. Valen glances at the wall-to-wall Gothic Revival buildings he passes, noting the conical roofs, polychrome brickwork, and arched windows of the aged structures. Valen recalls that these buildings date back to the 19th century, and he notes that the buildings are finished in colors such as middle brown, golden brown, and royal maroon.

As he saunters by the area's Pokémon Center, Valen can smell the aroma of various foods, such as spicy noodles, chocolate, and pizza fresh from the oven. However, he's not in Old Downtown to grab a bite to eat—he's here to look for someone.

Valen gets a phone call from Melanie, and he picks up. "I forgot to tell you that when you're famous, the time you could use to spend with friends can eaten up rather quickly," Melanie tells Valen. "I'm lying down on my bed because I'm so tired right now!"

"You can stay home and rest," Valen says. "Don't worry about me, as I heard an interesting piece of that I'm on my way to check out."

"Oh?" Melanie piques up. "What rumor?"

"Apparently, there's this popular Unovan trainer who arrived a couple of days ago. She's a lively person who's been cleaning up house," Valen explains. "Also, she's got a Serperior. You see where I'm going with this?"

"Do you think it's Rosa?"

"That's what I'm going to find out."

"I'm surprised you're actually going out of your way to do this," Melanie remarks. "You seemed very reluctant to even call her, and now you're looking for her."

"Assuming that it's her, of course," Valen says. "Anyway, I'll let you go for now. It sounds like you really need it."

"Thanks for understanding, and good luck."

"Thanks, I'll see you around," Valen replies.

After the call ends, Valen begins thinking about his time with Rosa in Unova, having a faint smile for a brief moment before returning to his indifferent self.

"I hope that she's okay with the current me," Valen muses. "A phone call isn't exactly the same as an in person encounter."

Then, Valen realizes that he just passed the district's public arena, which is a large square in between four large buildings. Before he can turn back, his eyes catch a familiar poster attached to a black Gothic lightpost.

Valen takes several deep breaths to call himself down—this is the second time he's seen a poster for the BW Agency. This one's got the same photo of Hilda on it.

A few seconds later, Valen decides to get back on track. He walks backwards until he's standing by the arena's entrance.

"If Rosa's in Old Downtown, she's definitely in here." Valen faintly smirks, sauntering into the arena.

Unlike the one he went to with Melanie, this arena's a large, reinforced concrete area with walls designed to shield buildings from damage. It's fully open on the front too.

Upon entering the arena, Valen immediately recognizes Rosa via one of her favorite accessories: her white and pink visor. Much to his surprise, there aren't any trainers around, except for a sulking Rosa.

"Awwwww, I got too carried away and they all left." Rosa frowns, staring at her white top with ice blue sleeves. The brunette girl's gaze is fixated on the Poké Ball plastered on her top's upper center, her long ponytails swaying due to a slight breeze.

Valen blinks in confusion, as he remembers that Rosa's not the type to feel down like this. He notes that all of her clothes are Grimsley Lauren. Her eyes her white and ice blue top, her mustard yellow shorts, and her black leggings, recalling that these clothes have been her favorite for years. Furthermore, Grimsley Lauren's been her favorite brand for years, with Guzmani being a close second. He also notes that she's still got her pink purse.

"Hey, you aren't allowed to be the person feeling down in the dumps," he calls out to Rosa.

Rosa perks up at this, her mouth falling open as she lets out a loud gasp. "That's voice...did he...did he really look for me in person?!"

"We can't have the life of the party feeling down, now can we? If that happens, we'll all be frowning."

Rosa can feel her skin tingling as an powerful feeling of euphoria starts to flow within her like a river.

"It's your boy, Valen," Valen greets with a faint glimmer of happiness.

"V-Valen...finally...my optimism paid off." Rosa whimpers.

Valen's mouth drops open. "You okay?"

Rosa's mouth curves into an ear-to-ear grin. "Valeeeeeeeeeey! Hiiiiiii!" She dashes towards Valen. She wraps her arms around Valen neck. "I can't believe it's you! I missed you soooooo much, Valey!"

Valen wraps his arms around Rosa's mid-section, feeling warmth flowing through his body. "It's good to see you again, Rosa."

As his eyes moisten up, Valen presses his lips together to prevent himself from broadly smiling.

"Well, I guess that there wasn't much to worry about." Valen allows his mouth to curve into a faint smile.

"I'm so glad to see you again." Rosa affectionately smiles, shedding a stream of tears. "I knew you would be back, and I was right."

Valen's eyes widen when Rosa kisses him on the lips.

"Oooooh, is my favorite booooy blushing?" Rosa giggles.

"A kiss? I thought-"

"Ground control to Valey!"

"If you don't let go of me, we can't have a Pokémon battle," Valen says. "The Rosa that I know jumps at the chance to battle."

"Nice try, but you aren't escaping meeee just yeeeet!" Rosa giggles, still embracing Valen with her eyes closed.

"Uh oh, looks like somebody is afraid of losing to me," Valen teases, his faint smile turning into a wide grin.

Rosa and Valen let go of each other, and Rosa takes a few steps backwards. "I'm going to defeat you in a Pokémon battle and then you'll be unable to escape me!" She proclaims, flritatously winking.

"I'm ready to cause mayhem."

Rosa gasps, placing her left hand over her mouth. "Oh noooooo, I forgot to tell you that I'd arrived! I was going to surprise yoooou by calling yoooou!"

"Don't worry about it." Valen shrugs, his eyes closed. "You texted me like eleven pictures of yourself."

"Ooooh, you're right!" Rosa giggles. "I'm sooo silly!"

"I did challenge you to see who finds who first."

"Yeeeep, you woooooon!"

"Battle time."

"Kaaaaaaaay, you're on!" Rosa happily closing her eyes. She twirls in a full circle, announcing, "Battle Queen Rosa's in the house!"

"Yep, still the same." Valen faintly laughs.

"So, many battles have you won so far in Calvana?" Valen asks, standing on the opposite of the area from Rosa. Valen holds a Poké Ball in his right hand.

"Yeah, I know what you're thinking: Did she win six battles, or only five?" Rosa asserts, pretending to be serious by lowering her eyebrows and looking stern. Then, Rosa reverts back to her usual self, sporting a joyful grin. "Well, I lost track of the amount because of all the excitement!" Rosa's Serperior is in front of her, ready to partake in another battle.

"I still love your energy." Valen smiles. "Hi, Serperior."

The green, serpentine Pokémon lets out a slight cry, acknowledging Valen.

"Now, you know that Pokémon battling is like my favorite thing ever, so let's get down to business!" Rosa cheerfully proclaims. "I'm sticking with my Serperior! She's been on a winning streak, so let's see if her winning streak will continue, or if you can end her winning streak!"

"You still think you can defeat me, Rosa?" Valen asks. "Your cuteness can't save you in battle, cinnamon bun."

Rosa slightly blushes, countering, "I know I can defeat you, my knight." Rosa's eyebrows angle downwards, giving Valen a confident, lopsided grin.

"Hmph, I'm still the big bad trainer who beats you down without ever letting up." Valen smirks. "Rosa, you wanna see what Armageddon looks like? I'm gonna show you."

"Bring it on!" Rosa narrows her eyes and fixates a competitive glare at Valen. "Guzma's protégé doesn't scare Battle Queen Rosa!"

"I'll use my Gengar," Valen states, pressing the button on the Poké Ball to let his Pokémon out. The grinning, red-eyed ghost lets out a sinister snicker and flexes his arms like he's a human bodybuilder, showing that he's ready to battle.

"No more waiting, Valen! It's time to get this started!" Rosa exclaims with excitement and joy, as it's been a long time since she has battled Valen. "Use Growth!" A light green aura of energy begins to form and surround Serperior, who lets out a battle cry. The aura glows brighter and brighter, and her power increases. Eventually, the light green aura dissipates.

"Good choice," Valen compliments Rosa, his mouth curving into an approving but confident smile. "However, will the boost in her special offensive power really be enough to win?"

"We'll find out! Use Energy Ball!"

Serperior opens her mouth and a glowing, green orb of energy begins to form in front of it.

"Gengar, use Shadow Ball."

At the same time, Gengar places his hands in front of his body, a black and purple sphere of energy forming in between his hands.

Gengar uses his left hand to launch his sphere of energy at Serperior, who fires off her orb at the exact same time. Both attacks collide with each other at great speed, causing them to cancel out. The collision causes a medium explosion, and smoke bellows as a result.

"Ice Punch," Valen commands.

As the smoke fully clears out, Gengar charges at Serperior via the air with his right hand, which glows icy blue. However, Rosa smiles with determination. She's prepared to counter.

"Leaf Blade!" Rosa commands.

The three leaves on Serperior's tail glows light green, and Serperior swings her tail to block the Ice Punch attack. Gengar and Serperior glare at each other with a fierce determination to come out on top, as both Pokémon struggle to push the other back.

"I see that you're still a formidable opponent," Valen remarks. "This'll be a lot of fun, even though fun and I don't mix that often anymore."

"Oh, is that so?" Rosa teases, her dark blue eyes fixated on both Valen and the battle. "I don't think you'll be saying that after our battle! Rosa makes everything two hundred trillion times more fun!"

"Gengar, fall back and use Sludge Bomb!" Valen commands.

Gengar backs up, and Serperior swings her tail again in an attempt to strike Gengar with her Leaf Blade attack, but Gengar's able to evade it just in time. Then, Gengar opens his mouth and fires off a barrage of brown sludge that all have a glowing, purple aura enveloping them. Serperior is struck just under her coiled, dark green extensions that form a V shape under her head. Serperior is sent reeling from the attack, and bows downward.

Suddenly, Serperior glows purple, indicating that Sludge Bomb has caused the poison status condition.

"Uh oh, that might not be a good sign for us!" Rosa professes.

"Use Hex." Gengar's mouth falls open, the grinning ghost letting out an eerie laugh. A pair of menacing, blood red appears above Gengar.

The eye begins to glow, causing a blood red aura to form and envelop Serperior. She lets out a distressed yelp as the aura becomes thicker, looking like it's sapping away her vitality.

"Ice Punch again."

Gengar's right hand glows icy blue, and he charges at Serperior. This time, Gengar lands a blow to Serperior's face, sending the Grass-type Pokémon reeling further.

Neither Rosa nor her Serperior will give up so easily. "Giga Drain!"

Before Gengar can back away, Serperior entire body glows with a green aura. Four large streams of energy extend outwards and latch onto Gengar.

The energy streams glow a brighter green as Serperior sucks away Gengar's own health to heal itself. Gengar closes his eyes and his sinister smile curves downward as it attempts to endure this attack, which is doing a number of Gengar, even though he is part Poison-type. Eventually, the energy streams fade away, as does the glow enveloping Serperior. Gengar falls to the ground, but he's able to get back onto his feet, albeit feeling a little weary.

"Dragon Pulse!"

As Gengar attempts to regain his focus, Serperior opens her mouth and a vibrant green ball forms in front of it. Serperior fires off the ball, which instantly turns into a serpentine-like dragon with small wings attached to the center of the body. The dragon formation slams into Gengar's face, sending the Ghost-type staggering backwards. However, Gengar manages to keep his footing.

"Well well, this a new development," Valen notes in a slightly surprised tone.

"You must've forgotten, you silly boy!" Rosa giggles. "Speaking of Dragon Pulse, I still remember how many Team Plasma grunts Salamence took down with his Dragon Pulse!"

"Heh, you should be focusing on Gengar," Valen reminds Rosa, folding his arms, sporting a faint smile on his face. "You'll get to see that dragon soon enough."

"I'll just have to make you send him out!" Rosa proclaims, sporting a confident smile. "Battle Queen Rosa's going to defeat you, then you'll see that you need your dragon to win against me!"

"Hmph, keep dreaming," Valen teases, sporting a cocky smirk.

"Be careful what you wish for, sweetie," Rosa playfully counters with a coy smile, while also giving Valen a flirtatious wink. "You're in my dreams more than you think."

"Uh oh," Valen muses, faintly blushing. "Please don't get me flustered."

"Oh noooo, I triggered Cursed Body!" Rosa yelps, snapping Valen back into focus.

Rosa's noticed that Serperior's been enveloped in a dark purple aura that's in the shape of Gengar. "Serperior can't use Dragon Pulse for a bit!"

"Reminds me of the time you forgot Moxie existed," Valen teases. "I bet that still stings."

"Hmph, don't get so high and mighty with me," Rosa teases back, sporting a playful grin. "You're still gonna lose."

"Are we gonna keep talking or are we gonna continue this battle?" Valen grins. "C'mon, I've got a battle to win."

Rosa smirks, commanding, "Use Frenzy Plant!"

"I was wondering when she'd use that."

Serperior's body glows green again, and she slams her tail on the ground, causing massive roots with spikes on then to spring up all around Gengar, with all the roots striking Gengar at once, dealing a massive amount of damage. Serperior pants, having still taking poison damage this entire time.

Gengar falls to the ground, his grin flipping upside down. However, Valen doesn't say anything. He keenly studies the battlefield, musing, "Gengar looks like he was just defeated, but something doesn't feel right about this."

Then, Valen realizes what Gengar's doing. "Heh, that little trickster."

"We did it! We won! We actually defeated Valen!" Rosa states triumphantly, forming a fist with her right hand and raising it towards the sky. Despite panting due to being worn out from this battle and previous battles, Serperior lets out a victory cry.

"We did it, we-huh?"

Much to Rosa's shock, Valen isn't recalling his Gengar, remaining quiet with his eyes closed.

Even more surprising to Rosa, a confident smirk is plastered across Valen's face. "Uh, why aren't you recalling your Gengar, and what's with that face?" Why Valen won't recall a Pokémon that has been defeated? After all, Gengar lost the battle...or has he?

"Use Shadow Ball."

Gengar begins to snicker loudly, and he stands back up on his legs. It turns out that Gengar had faked being defeated.

Rosa jumps backward, her jaw dropping. "S-Seriously?!"

A wide-eyed Rosa watches as Serperior's sent reeling from the black and purple sphere. Rosa's battled many times, but she can't remember encountering a Pokémon who faked being defeated.

"Never, ever let your guard down in a battle," Valen states, narrowing his eyebrows downwards and still smirking.

"This battle is now mine! Gengar, use Sludge Bomb!" Once again, Gengar opens his mouth and fires a barrage of brown sludge that glow purple at Serperior. This attack also hits, sending Serperior reeling further as she bows downwards.

The damage Serperior's taken has piled up, and she's worn out from previous battles. Combined with additional damage from poison, it's too much. Serperior lets out a faint cry, crashing into the ground

"T-This wasn't supposed to happen!" Rosa cries out, shutting her eyes.

"That's my boy," Valen compliments his Gengar. Both trainer and Pokémon exchange a fist bump.

"I've never had an opposing Pokémon fake their defeat before!" Rosa pouts.

"His tactic was rather unusual for a battle," Valen admits as he recalls his Gengar. "It took me a moment to figure out what he was doing."

"I think I got a bit carried away," Rosa admits as she recalls her Serperior. She places Serperior's ball back into her purse.

"Despite that, that battle was loads of fun! You're still as strong as ever!" Rosa cheers, clasping her hands in front of her with a broad smile and her eyes closed.

"Give yourself credit as well, as you're also just as strong as I remembered," Valen counters with a faint smile of approval. "Now, I'd say that we'd go be meeting Melanie, but she's rather tired from everything she's had to do lately. "You also need to meet Arthur, whenever he decides to show up again."

"Oooh, a new friend for meeee!" Rosa lifts her right foot off the ground. "In addition to battling, I also looove to meet and talk to people. That's another reason why I'm the popular girl! I can't wait to see Melanie again as well!"

"Come on, walk with me." Valen tilts his head towards the entrance/exit. "We have some catching up to do."

"Some catching up?! You're soooo silly, Valen!" Rosa giggles.

"I'm surprised to see you in Old Downtown," Valen admits to Rosa as the two of them walk side by side down the cobblestone plaza walkway.

"I saw all these old and cool buildings and I was so amazed by them!" Rosa states in a peppy manner, feeling like she just went back in time.

"So, how long are you staying in Calvana?" Valen asks, glancing rightward towards Rosa.

"I'm just visiting for now, but I'm considering living abroad in Calvana." Rosa smiles, giving Valen an affectionate smile. "I have never lived abroad before, and this region looks like so much fun."

"Is that why you picked this region for your goal?" Valen asks, sporting a faint, friendly smile.

"Yep," Rosa replies, giving Valen an adoring smile. "I want to make a name for myself here, but I really wanted to see you again in person. I know I've said it already, but I really missed you."

"Likewise."

"Hey, have you contacted anybody else that you met abroad?" Rosa asks. "Calem, Serena, Lillie, Gladion, Silver, Hilda, anybody?"

"Nope."

"Wait, you still haven't talked to anyone else from abroad?!" Rosa backs up a few feet.

"I don't like socializing anymore, but let's just say that I like you more than I hate socializing." Valen turns away, his face burning up.

"R-R-Really?! Y-You really mean it?!" Rosa asks as she blushes.

She sports an affectionate grin upon noticing Valen's demeanor. "Tee-hee, he's soooo cute when he's flustered!"

Serperior can learn Dragon Pulse via move tutor in Gen 5, Gen 6, and Gen 7.

Rosa's a very playful young adult in her early twenties.

Did you enjoy seeing Rosa and Valen reunite in person? Any other thoughts about Rosa? How about the battle? Valen's reaction to seeing a second poster with Hilda on it?
