Entrance to the mansion and conversation between sisters (Canonical route)

The beam from Lucia’s Poltergust cut through the gloom, illuminating the peeling wallpaper and the pair of glowing eyes that blinked lazily from the stairwell. Maria adjusted her grip on the G-01, the hum of the machine vibrating against her palms. "So," she muttered, side-eyeing Lucia as they crept forward, "what’s the deal with Boos? Besides the whole ‘floating and grinning’ thing."

Lucia’s smirk was audible. "Oh, you don’t know? Princess Peach never gave you the ‘Boo safety talk’?" She ducked as a spectral hand swiped at her cap. "They’re perverts. Like, next-level perverts. Get possessed by one, and they’ll ride you harder than Yoshi on a sugar rush—except they’re using your body to do shit you’d never soberly consent to."

Maria snorted. "Bullshit."

"Try me." Lucia pivoted, sucking a leering Boo into her Poltergust with a wet shlorp. "Ever seen a ghost fuck a toaster? Because I have, and it was not my idea." She shuddered. "And if one licks you down there? Congrats, you’re now horny for spooky dick. It’s like ghost pheromones or some shit—turns your brain into horny soup."

Maria’s steps faltered. "What."

Lucia’s grin was all teeth. "Oh, don’t tell me the great Maria’s never been curious—"

"Shut up," Maria hissed, cheeks burning as she stomped ahead, only to freeze when a giggle whispered against the back of her neck. She spun, Poltergust raised—but the hallway was empty.

Lucia’s laughter echoed off the walls. "Relax, hero. Just don’t let ‘em sneak up on you. Or under you." She waggled her eyebrows. "Unless you’re into that."

Maria flipped her off just as a chill raced up her spine. She whirled—too slow. A Boo materialized inches from her face, its grin splitting wide like a rip in reality. "Maaaariaaa," it crooned, tongue lolling obscenely.

She jammed the Poltergust nozzle into its chest. "Nope." The vacuum roared to life, the Boo’s wail dissolving into static as it vanished down the tube. Maria exhaled sharply. "Okay. Maybe you weren’t entirely full of shit."

Lucia patted her shoulder. "Told you. Now watch your—shit!"

Maria ducked on instinct. A spectral hand grazed her overalls where her ass had been half a second prior. She didn’t need Lucia’s yelp of "They’re going for the butt!" to know what that meant.

The sisters stood back-to-back, Poltergusts humming in unison as the hallway filled with drifting Boos, their grins widening in anticipation.

"Just like old times," Lucia muttered.

Maria adjusted her grip. "Except now I know you’ve fucked a ghost."

Lucia’s indignant squawk was drowned out by the cacophony of suction and spectral screams.
