A/N: This chapter has it's final revision as of 4/23/2026. This is a major update and I hope you enjoy.

 

---

Four hundred slime girls packed into the Grove at dawn, and the first thing that happened was that no one could stop moving.

 

Four hundred heart-cores vibrating at the exact same frequency created a massive, uncontrolled resonance loop that warmed the air until the barrier humming around the basin sounded like a massive, contented purr.

 

It also meant everyone's gel forms went loose and elastic. The commons girls especially. They ran hotter than most and were the first to start losing their edges.

 

Community-type slimes always went structurally honest in a crowd.

 

And honest, for slime girls at four hundred collective heart-cores, meant: softened, lower, fuller at the hips and chest where substance naturally settled when the surface tension eased.

 

The whole Grove looked like a community that had exhaled. Rounder, more present than they'd be in an hour, when the morning cooled and everyone tightened back up.

 

"Purin's melting again," someone observed from the long table.

 

"Purin's been melting since March."

 

Near the south stones, a deep violet girl had gone so soft she was pooling from the waist down. Her upper form was still completely animated; her lower half was its own sovereign territory, and she was not remotely concerned about the separation.

 

Two amber commons had merged at the shoulders. They negotiated the extraction with practiced calm and a considerable amount of full-body contact. Breasts pressed flat against breasts, hips sliding past hips.

 

Nobody looked twice. Four hundred slime girls, four hundred sets of breasts at varying degrees of translucency and bounce. The morning had long since stopped being the time anyone pretended to notice.

 

Near the center of the gathering, Mochi was leaning forward at a perilous angle, soft white hair bouncing with her, completely absorbed in a conversation.

 

This presented a view of her lower form that the basin had collectively, and accurately, dubbed Mocchi Butt.

 

It was opaque, cream-white, structurally defiant, and currently acting as a literal trampoline.

 

Two younger commons ricocheted off it with delighted squeaks, flattening into puddles on the grass before their surface tension snapped them back into shape to try again.

 

"Mochi!" Chamoy's voice cut across the Grove at full volume. "Your butt ate those girls!"

 

"They're FINE!" Mochi called back without turning around. "They like it!"

 

From across the fire, Boba backed her up immediately: "They do like it!"

 

The full weight of Mochi's lower half absorbed each impact, compressed, and released with a generous bounce that should have stopped being distracting four hundred viewings ago.

 

They had. It was still distracting.

 

Mochi didn't even blink. She continued her story with cheerful, bouncy enthusiasm, her upper form gesturing wildly while her lower half conducted its own entirely independent program of jiggle and rebound.

 

Agar had stationed herself at the Grove's edge, where the grass was still damp and the canopy light came through amber-gold.

 

She was smaller than most of the gathering—slim, pale pink, her hair a soft translucent rose that fell just past her shoulders and caught the canopy light like tinted glass.

 

Her wrap was loose Archaean-issue, warm cream and rose-pink fabric that sat easy on her frame.

 

Her own form held its shape under heat. Agar-agar didn't flow like the commons did. It stayed compressed, cool at the core, while everything around her went soft and generous in the resonance.

 

She stood at the Grove's edge and watched the loosening happen to everyone else.

 

"I have been documenting the resonance pattern," Crema said, stepping up beside her.

 

Crema was crema-de-leche. Pale amber-rose, translucent at the edges, and denser than she needed to be. Structure was a personal choice, and she made it consistently.

 

Her hair was warm brown, pinned up and out of the way. It had been in exactly that arrangement since she woke up.

 

She pushed up a rose-tinted gel visor that she had explicitly molded over her eyes just for this purpose. It caught the morning light with a sharp glare.

 

"The harmonic peak arrives at an average of seven minutes," Crema said. "We are currently at three minutes and forty seconds. Also, Nata is about to destroy the eastern perimeter."

 

"Wait, what?" Agar spun around.

 

"I CAN LIFT IT THIS YEAR!" Nata roared.

 

Across the Grove, the aggressively dense nata de coco girl was currently glowing bright, angry orange.

 

Short hair wild around her jaw, thick arms locked around the stone, her whole compact, broad-shouldered frame operated at a completely different register from its usual caramel-warm ease.

 

She had wrapped her arms around one of the massive ceremonial anchor stones and was straining so hard her surface was starting to bubble.

 

"Nata, drop it!" Agar yelled.

 

"MY POWER IS MAXIMUM!" Nata yanked upward.

 

The stone didn't budge. But the sheer force of her pull caused her arms to snap like rubber bands, launching her backward into a tree with a spectacular, echoing THWACK.

 

Leaves rained down.

 

A beat of silence passed before Nata gave a shaky thumbs-up from the bushes.

 

"She gets closer every year," Crema noted, deadpan, scribbling furiously in her notebook.

 

Agar just sighed, pressing a hand to her face to mask her expression.

 

Her heart-core pulsed. Loud, chaotic, and completely ridiculous.

 

Home.

 

"You're doing it again," Crema said, without looking up from her notebook.

 

"Doing what?"

 

"Smiling at the chaos like you invented it."

 

Agar's mouth closed. Her heart-core dimmed slightly, pulling back behind her ribs where she preferred it.

 

The barrier's hum wrapped around them all. Agar's denser form sat quietly inside it, resisting the current while everything else flowed.

 

Near the eastern path, Gelée had already stepped back from the main gathering.

 

Sea-green and cool, her hair a soft pale green that fell smooth past her shoulders. She looked like she belonged in every space she occupied, which was always slightly apart from the center.

 

She was facing the treeline. Not watching. Not waiting.

 

Just: positioned. The way a door was positioned when someone had already opened it once and set it back.

 

From somewhere behind her, Crema said, flatly: "Seven minutes."

 

Then the hum screamed.

 

It wasn't a sound. It was an absence of sound so violent it made Agar's teeth ache.

 

The barrier didn't just fade—it felt like someone had taken a massive, invisible hammer to the atmosphere.

 

The warmth vanished.

 

In its place, a crushing, suffocating heaviness slammed into the Grove. Like gravity had suddenly doubled.

 

Around Agar, the laughter cut off instantly.

 

Three of the younger commons who had been bouncing off Mochi went liquid entirely. Their forms spread across the grass in an uncontrolled scatter, unable to hold their shapes against the weight.

 

Agar's response was the opposite: her form seized up.

 

The agar-agar of her went dense and opaque in a single involuntary clench, her edges sharpening as her substance compressed inward.

 

The body doing what bodies did under sudden load when they were built to hold rather than flow.

 

"Crema?" she managed, knees buckling against the pressure even as her upper form locked tighter.

 

Crema's gel visor cracked down the middle.

 

"Anomalous pressure. Direction: east." Her voice had lost its usual cool detachment entirely. It was shaking.

 

Agar forced her head up, looking past the ancient trees.

 

They hadn't waited for scouts. They were already here.

 

Standing just beyond the canopy line were three silhouettes. They didn't move like anything from the basin—no fluidity, no organic bounce.

 

They stood with an unnatural stillness, the stillness of something that has already made its assessment. Their eyes tracked the Grove without searching: not looking for something, having already found it.

 

The pressure radiating off them swept across the gathering in systematic passes—measuring, cataloging, the way a predator counts what it will take.

 

One of the shadows took a single, deliberate step forward, crossing the tree line.

 

Nori was already writing.

 

Someone peered over her shoulder and read aloud: Count: unknown, est. 3. Movement: decided. Not from here. Direction: east. Did not approach. Did not attack. Looked at everything.

 

They're coming in.

 

Panic erupted. Nata scrambled out of the bushes with leaves in her form and her substance still rattled from the impact. The dense coconut-white of her was looser than it should have been, her arms losing density when she tried to form them into blades.

 

"I can't—" Nata's arms went soft at the elbow. "I CAN'T HOLD SHAPE."

 

The pressure was too heavy. Crema was frozen. The commons were crying out.

 

Across the Grove, Chamoy had been loudly promising what she would do if scouts ever came, and she was still doing it now. Both arms raised, form trembling hard under the pressure, voice not stopping.

 

"I TOLD YOU! I SAID THIS WOULD HAPPEN! I SAID—"

 

"Chamoy, shut UP!" Boba yelled from somewhere.

 

"I'M GOING TO FIGHT THEM WITH MY BARE—"

 

A few feet from her, Hibiscus stood with her full wine-crimson form squared toward the treeline. Unhurried. Certain. She'd already decided how this ended.

 

And Marzipan, pale ivory, had drawn herself up correctly and precisely, until the pressure spiked again and she went completely liquid for one half-second before hauling herself back together.

 

Agar ran the assessment in the time it took the leading shadow to cross the tree line.

 

Step forward.

 

Position between the Grove and the threat.

 

Output.

 

Her core had the same impulse. It moved first—ahead of her intention, unasked.

 

Deep inside her chest, her heart-core didn't warm up. It committed.

 

Thermal output spiked past anything she'd consciously produced. Viscosity dropped to near-liquidus in a single involuntary release.

 

The warm amber of her washed out entirely; her outline lost definition.

 

She was, clinically, a light source.

 

The pressure shattered.

 

Core temperature: dropping. Viscosity: beginning to return.

 

She had not authorized the release. That was information she'd need later.

 

The leading shadow froze. Its eyes—careful, cataloging, already calculating—snapped to Agar.

 

The light had given them exactly what they came to see.

 

For one long, agonizing second, it ran its assessment. Then, smoothly and without any sound at all, it stepped backward into the shadows. The others followed.

 

A moment later the oppressive weight vanished entirely.

 

She was on her hands and knees in the grass.

 

She was aware—distantly, in the part of her that filed things she didn't ask it to—that four hundred slime girls had just watched her form blow wide open.

 

Her edges weren't resolving yet. Substance still expanded, soft at the margins, the agar-agar of her translucent enough that her heart-core was fully visible through her chest.

 

Everything on display.

 

Core temperature: minimal, recovering. She pressed her hands flat to the grass. The internal reaction would wait. The repeatability didn't matter yet.

 

What mattered was the grass under her palms, cool and real, and the slow return of her edges.

 

Four hundred slime girls were staring at her.

 

Somewhere in the silence, Chamoy whispered: "What the hell was that."

 

It wasn't a question. Nobody answered it like one.

 

Nori materialized beside her. Deep green, lean, dark hair cut short, iridescence shifting across her surface like oil on water. She held out a wooden bowl.

 

Agar looked up. "Nori... what?"

 

"Soup," Nori said, her face an unreadable mask. Her hands were trembling, slightly. "It needs salt. Also, you should probably call Obi."

 

At the back of the Grove, Ori hadn't moved. She was watching the eastern canopy with the expression she wore when she already knew how a thing ended.

 

Agar reached into her core's resonance and sent the emergency pulse. The one that meant: drop everything.

 

The hum didn't come back.

 

The shadows were gone, but they had retreated with what they'd come for. Whatever had erupted out of Agar's chest, they had seen it. Measured it.

 

They would factor it into everything that came next.
