MHA - 1a and 1b beach trip

The late-summer sun hung high and merciless over the private stretch of coastline U.A. had somehow secured for the day, Takoba Municipal Beach Park. turning the water into a sheet of glittering blue glass and the sand into soft, golden heat. The air smelled of salt, sunscreen, and the faint metallic tang of someone’s half-forgotten hero costume still drying on a towel.

Class 1-A and Class 1-B had invaded the beach with the chaotic energy of twenty-plus teenagers who had finally been allowed to stop fighting for their lives for one single afternoon.

The girls had claimed the shallows. Mina Ashido’s pink skin practically glowed as she leapt for a spike, acid carefully dialed down so it only made the volleyball fizz harmlessly on contact. Ochako floated just high enough that her feet barely skimmed the surface, laughing every time Tsuyu’s long tongue snapped the ball out of the air with perfect frog precision. Momo, ever the over-preparer, had created a set of waterproof scoreboards and was currently arguing the rules with Itsuka Kendo while Ibara Shiozaki’s vine-hair formed a living net. Tooru’s invisible hands kept batting the ball from unexpected angles, making everyone scream in delighted confusion. Pony Tsunotori’s horns doubled as perfect spiking platforms, and she kept yelling cheerful (if slightly mangled) English encouragement.

Meanwhile the guys had turned the shoreline into a full-scale water-gun warzone. Denki’s “taser shots” kept short-circuiting whenever he overcharged them, leaving him twitching and giggling on the sand. Kirishima had hardened just enough that the streams bounced off him with satisfying thwacks, bellowing “MANLY!” every time he took a hit. Tetsutetsu was doing the exact same thing ten meters away, the two of them somehow competing over who could get wetter without flinching. Sero’s tape kept turning into makeshift water-balloon launchers until Mineta tried to stick one somewhere extremely inappropriate and received an immediate, expertly aimed slap of tape across the face.

Speaking of Mineta—Hanta Sero had appointed himself official Mineta Containment Unit for the day. Every time the grape-headed menace started eyeing the volleyball game with that familiar gleam, a strip of tape would snag an ankle or wrist and yank him back into the boys’ zone with a cheerful “Nope, little dude, not today.”

Bakugo, of course, was not participating in anything so childish as water guns. He was currently sprinting barefoot across the wet sand, explosions popping from his palms just hard enough to propel him forward while he roared at the top of his lungs:

“GET BACK HERE, YOU DAMN NERD! I SAID THE LAST ONE TO THE WATER HAS TO BUY EVERYONE ICE CREAM AND I’M NOT PAYING FOR YOUR BROKEN WALLET!”

Izuku, already soaked and grinning like an idiot, was weaving between beach umbrellas with the kind of panicked agility only years of running from Bakugo could produce. “Kacchan, that wasn’t even a real race—!”

Under the largest cluster of umbrellas, the adults had formed a quiet fortress of shade and cold drinks. Aizawa lay half-zipped into his yellow sleeping bag on a wide beach towel, one arm loosely draped over a, white-haired figure curled against his side. Eri’s soft breathing rose and fell in perfect sync with the distant waves; a half-melted popsicle stick rested forgotten in her small hand. Recovery Girl sat nearby in a folding chair that somehow still managed to look like a throne, muttering about “foolish children and sunburns” while periodically forcing electrolyte packs on anyone who wandered too close. Vlad King was loudly arguing the superiority of Class 1-B’s volleyball technique with Present Mic, who had somehow brought a portable speaker and was blasting beach rock at a volume only he considered “chill.”

Tokoyami and Shoji had claimed the absolute driest patch of sand farthest from both the water and the main group. Dark Shadow was currently holding a large umbrella at a precise angle while Shoji’s duplicated arms carefully brushed every single grain of sand off Tokoyami’s feathers and his own mask. They looked like two people preparing for a formal tea ceremony in the middle of a warzone.

Everything was noisy, bright, and—miraculously—peaceful.

Then Mineta’s eyes locked onto you.

You, the brand-new transfer student who had only been in Class 1-A for a week. The one still figuring out where the good seats were and how to survive Bakugo’s morning death glares. The one currently standing a little apart from the chaos, maybe still deciding whether to join the water fight or the volleyball game or just quietly melt into the sand.

Mineta’s entire body language changed in a single heartbeat. The sticky balls on his head seemed to quiver with sudden purpose. He slipped Sero’s latest tape lasso like a greased grape and launched himself across the sand with the single-minded determination of a tiny, purple missile.

“NEW GIRL—I MEAN, NEW STUDENT—WAIT UP! I JUST WANTED TO SHOW YOU THE SPECIAL SUNSCREEN I BROUGHT THAT ONLY WORKS IF I APPLY IT MYSELF”

Sero’s voice cracked across the beach like a whip. “MINETA, I SWEAR TO GOD—”

Bakugo actually stopped mid-chase, explosions sputtering out as he stared. “What the hell is the grape doing now?!”

Izuku nearly face-planted into the surf, eyes wide with pure secondhand horror.

Mina’s volleyball spike went wildly off-course. “Oh no he did not—”

Tsuyu’s tongue paused mid-air. “Ribbit. This is going to be bad.”

From the shade, Aizawa’s visible eye cracked open just enough to convey the promise of absolute annihilation if the situation required it. Eri stirred but didn’t wake, only burrowing closer against his side.

And you—brand-new, still slightly out of place, and suddenly the absolute center of Mineta’s entire universe—had approximately three seconds before the shortest, stickiest problem in Class 1-A closed the distance.

The peaceful (or at least relatively peaceful) beach day had lasted all of forty more minutes.

One second Eri was curled against Aizawa under the big umbrella, popsicle stick still loosely clutched in her tiny hand. The next, the yellow sleeping bag was empty.

Aizawa’s eyes snapped open so fast it was like someone had flipped a switch. He sat up in one smooth, panicked motion, scanning the sand with the kind of intensity usually reserved for villain raids.

“...Eri?”

Silence.

Then every adult under the umbrellas went rigid at the same time.

Recovery Girl’s cane hit the sand with a sharp tap. Vlad King’s head whipped around so hard his fangs nearly clicked. Present Mic actually turned the music off. Even the distant volleyball game and water-gun war seemed to sense the sudden drop in temperature.

Aizawa’s voice was low, controlled, and absolutely terrifying.

“Everyone stop. Eri is missing.”

Chaos exploded.

Mina shrieked and dropped the volleyball. Ochako shot straight up into the air like a startled balloon. Tsuyu’s tongue shot out in six different directions at once, tasting the wind. Bakugo’s palms started sparking as he barked, “HOW THE HELL DO YOU LOSE A TINY WHITE-HAIRED PERSON ON AN OPEN BEACH?!” Izuku immediately started hyperventilating and muttering search-grid strategies under his breath. Kirishima and Tetsutetsu both hardened and began charging toward the dunes like twin tanks. Shoji’s arms multiplied so fast he looked like a panicked octopus. Tokoyami’s Dark Shadow ballooned outward in pure protective fury, muttering something about “the darkness claiming the innocent.”

Sero had Mineta in a full-body tape cocoon before the grape boy could even think about volunteering for “search duty near the girls.”

Iida began chopping the air and assigning search sectors at the top of his lungs. Momo created a stack of laminated “MISSING ERI” posters in under three seconds. Kendo was already herding Class 1-B into organized pairs. Monoma, for once, shut up completely and just looked genuinely worried.

Aizawa was already on his feet, capture weapon unspooling, red eyes glowing as he scanned every possible hiding spot with Erasure active out of pure parental terror.

“ERI!”

“ERI-CHAN!”

“Where’d the little listener go?!”

Then—

A soft, familiar giggle drifted over from the direction of the ice-cream stand near the boardwalk.

Every single head snapped toward the sound so fast it was a miracle no one got whiplash.

There you were.

a pro hero to the looks of it that none of them have ever seen before walking calmly in the sand, looking around like you were trying to find someone, while a very happy Eri held your hand. She had a bright blue ice-cream cone clutched in both small hands (the good kind with the little chocolate flakes), and a smear of it already on her cheek. Her white hair was slightly windswept, and she was giggling at something you’d just said, completely unbothered by the small army of panicked heroes and hero students now staring at the two of you.
