Before he could protest, she pulled him along, both of them leaping from rooftop to rooftop. Their movements were silent, their speed nearly impossible to track, two black silhouettes dancing across the skyline.
The city fell behind them, replaced by the wide-open coastline. The salty breeze hit Izuku first, and his nose twitched instinctively.
"Are we going straight to swimming?" He asked, curious but wary of her smirk.
"Of course not."
Before he could react, Rumi's grip on his arm tightened. She twisted her body, using the momentum to sling him into the sand below. Izuku twisted mid-air, landing on his back with a loud whump as the impact sent sand flying in all directions.
"Never drop your guard around me!" She shouted triumphantly, landing with a heavy thud next to him.
Izuku grinned up at her, barely winded. "Neither should you!"
He shot a hand out from the sand, grabbing her leg and tripping her with a swift tug. Rumi hit the ground hard, but before she could retaliate, dark tendrils surged out of the sand, wrapping around her wrists and holding her in place.
Her face lit up with exhilaration. "Using your quirk now, huh? Oh, you're really asking for it!"
Izuku chuckled, brushing sand off his clothes as he stood. "I figured I might need the extra help tonight."
Rumi tugged against the shadows, but they held firm—enough to keep her down but not hurt her. She lay back in the sand, catching her breath with a lopsided grin.
"You're getting cocky, kid" She teased, her voice full of pride rather than annoyance. "But I like it."
Izuku extended his hand, and the shadows loosened, allowing her to sit up. She grabbed his hand firmly, pulling herself to her feet with a smirk.
"This is gonna be a long night for you" She warned playfully.

Meanwhile. 
After a long day at work, the thought of unwinding with a late-night swim alongside two of her closest friends was all that ran through Ryuko's mind as she glided over the shimmering city skyline.
This, she knew, was a rare occurrence—especially considering Rumi of all people had agreed to join. The Rabbit Hero had always been vocal about her dislike of swimming, grumbling about how it ruined the fur of her ears and tail. So, for Rumi to indulge herself tonight? It had to be a once-in-a-lifetime event.
Unlike Rumi, though, Ryuko loved the water—particularly the cold. It calmed her down, cooling the constant warmth that came with her dragon physiology. Dragons were known for their high body temperatures, and Ryuko was no exception. In the sweltering summers, the heat drained her mercilessly, to the point where she'd joke that her sweat alone could fill an Olympic-sized swimming pool.
Of course, that was an exaggeration—mostly.
Still, Ryuko didn't mind summer itself; it was just the oppressive heat she couldn't stand. So when opportunities to cool off came her way, especially ones that included her friends, she never passed them up.
But as she flew closer to their usual meeting spot, the calming anticipation was shattered by the sudden, unmistakable sound of a thud that echoed through the air.
Her eyes narrowed, and her instincts flared to life. What was that? she thought, her wings beating faster as she sped toward the source of the sound.
The closer she got, the clearer the scene before her became—and what she saw made her jaw drop.
The moment she landed, her eyes widened at the sight before her. "Izuku?! Rumi?!"
