The Pantheon

The Sensational Sisters

Ashley slowed her pace as the Cerulean Gym came into full view. The late morning sun reflected off its domed roof, giving the blue-tinted glass a ripple effect, like the surface of a serene lake. Right at the top, perched proudly like a mascot keeping watch, was the stylized sculpture of a Dewgong, mid-leap. Its tail curled up like a wave, its face frozen in a permanent smile.

She stopped at the edge of the sidewalk, one hand resting on her hip, the other shielding her eyes from the sun as she stared at it.

“Okay, that’s adorable,” she muttered to herself, grinning.

She didn’t have any of her Pokémon out. Not for this part. No need to show her cards just yet, especially not to a Gym Leader—or, in Cerulean’s case, Gym Leaders. She’d done her homework. The Sensational Sisters were… unique. And judging by the massive glass panels and the subtle shimmer of water visible behind them, this gym definitely leaned into the aesthetic. Aquarium-core, she’d call it. The whole building looked like it belonged in a Seafolk Village rather than the middle of Kanto.

Ashley shifted her weight from one foot to the other, tugging lightly at the hem of her jacket as her mind wandered.

It really was wild how different each gym in Kanto was. Blaine’s was in the literal crater of a volcano. Koga’s looked like it was imported from some ancient era, and Erika’s? Walking into her gym was like stepping into a Miyazaki film. Sabrina’s gave off strong “abandoned lab from a sci-fi horror” vibes, all cold lights and humming psychic energy. And Surge’s gym… well, he was a military man, and his gym looked like it had been welded together from tank parts and leftover war decor.

She tilted her head slightly. “Wonder what Brock’s looks like… or Giovanni’s.”

But before she could get too lost in thought, movement caught her eye.

A group of men—at least twenty of them—stormed past her toward the gym entrance. Not in a threatening way. They were… coordinated. Like a school trip. Or a weird parade.

Each one wore shirts emblazoned with glittery versions of the Sensational Sisters' faces. Some held foam fingers. Others waved banners. A few even had light sticks—yes, actual concert light sticks that glowed faint pink and blue. One of them was fully dressed in a Seel onesie, and another had what looked suspiciously like a life-size Lily plushie slung over his shoulder.

Ashley blinked.

“What the—?”

They shuffled past in excited clumps, chattering loudly about “Cascading Grace!” and “Violet’s elegance!” and “Daisy’s perfect hair!” while throwing in terms like “battle-choreography,” “top-tier swim technique,” and “idol-tier stage presence.”

Ashley took a long, slow step back.

She watched one particularly enthusiastic fan nearly trip over his own feet as he fumbled to hold up his camera and a “LILY IS LOVE” sign at the same time.

Ashley raised an eyebrow. “So, uh…”

She folded her arms, lips twitching into a crooked grin. This was going to be something.

Not a single one of the men even looked at her. Too focused. Too laser-locked on whatever event—or performance—was happening inside.

Ashley stepped inside the Cerulean Gym and was immediately hit with the echoing roar of a crowd.

“Whoa—what the…”

Her boots clicked softly against the glossy tiled floor as her eyes adjusted to the dramatic lighting. The stands wrapped around the entire upper half of the gym, packed with people. Not just trainers—fans. Hardcore ones. Some wore shirts with stylized art of the Sensational Sisters. Others had towels draped over their shoulders like they were at a concert. A few were already waving little light-up foam Poké Balls like they were at a music festival.
