Ren Amamiya leaned against a pillar in the bustling Smash Bros. arena lobby, his gray eyes scanning the vibrant chaos of fighters from worlds he’d only glimpsed in games. His black hair fell messily over his fake glasses, a familiar ruse to keep his unassuming vibe intact. The invitation to Super Smash Bros. Ultimate had come out of nowhere—a glowing letter from the Smash organizers, sealed with a wax emblem of crossed swords. Now, as Joker, the Phantom Thief leader, he stood in a new kind of Metaverse, one where heroes and villains clashed for glory, not hearts. His red gloves flexed, itching for action, but the unfamiliarity of this place kept him on edge, his usual cocky flair tempered by curiosity.

You approached, a seasoned fighter from the roster, your presence cutting through the crowd with an air of confidence that matched the arena’s electric energy. Ren straightened, his slouched posture shifting as he caught your gaze. You introduced yourself with a nod, your demeanor welcoming yet sharp, like you’d sized him up already. He smirked faintly, adjusting his glasses. “Ren Amamiya. Or Joker, if you’re feeling dramatic,” he said, his voice low but laced with a playful edge, testing the waters.

You gestured for him to follow, leading him through the sprawling Smash complex. The lobby opened into a massive training hall, where Mario sparred with Link, fireballs clashing against steel. Ren’s eyes widened slightly, but he kept his cool, hands in the pockets of his Phantom Thief tailcoat. “Not bad. Beats sneaking through Palaces,” he muttered, glancing at you for a reaction. You pointed toward the training dummies, motioning for him to try them out. He summoned Arsène in a flash of blue flame, the Persona’s wings casting shadows as he slashed a dummy with precise dagger strikes, his movements crisp yet theatrical, like a dancer on a stage.

Next, you guided him to the trophy gallery, a gleaming hall lined with golden statues of every fighter. Ren paused at his own, labeled “Joker,” capturing him mid-leap with Arsène looming behind. “They got my good side,” he quipped, though his fingers brushed the plaque, a flicker of pride in his gaze. You led him past the dining hall, where Pikachu nibbled on berries and Samus sipped coffee. Ren’s stomach growled—he hadn’t eaten since Leblanc’s curry that morning—but he played it off, smirking. “Hope they serve something better than prison gruel.”

The tour ended at the arena’s edge, overlooking a floating battlefield where clouds swirled below. You stood beside him, pointing out the stage’s shifting platforms. Ren’s sharp eyes followed, already strategizing. “This place... it’s like Mementos, but louder,” he said, his tone half-serious, half-teasing. He turned to you, his smirk softening. “Thanks for the tour. Guess I owe you one. So, you gonna show me how to steal a win here, or what?” His playful challenge hung in the air, his trust in you budding as he adjusted to this wild new world.
