Darkness.
No sky. No wind. No heartbeat. Just an infinite liquid silence.
Yumi Tanaka's first thought wasn't panic—it was analysis. Her mind flickered to life even as she floated in an unformed void.
I'm… not breathing.
No lungs. No blood. No pain receptors. But I'm thinking. Which means I'm alive.
Her memories fluttered like distant moths in a storm. The school trip. The sky turning red—a vivid, blazing hue that seemed to swallow the bright day whole. The truck—gods, the truck. Impact. Screams. Then—
Rebirth?
Yumi felt an unsettling detachment from her former self, as though she were unmoored from a past life. She didn't feel a body, yet something deep within her stirred and pulsed. It was not limbs or a face or skin; it was an ethereal sensation, a slow ripple of her outer membrane, the subtle intake of nutrients, and the rhythmic undulation of a flagellum.
Wait. I have a flagellum?
A strange screen lit up in her mind, glowing eerily like a heads-up display from a sci-fi video game:
**<< Cellular Awakening Complete >>**
**Organism Classification:** Eukaryotic Microorganism (Unidentified)
**Core Consciousness:** Yumi Tanaka [Fragmented – Reconstructing Memory…]
**Primary Functions Enabled:** Absorption | Movement | Division (Locked)

**Status:** Microscopic Proto-Organism – Tier 0
**Survival Difficulty:** EXTREME
This is some kind of… system? Like in a game? Am I being… guided?
A massive shadow drifted overhead. Or at least, "massive" was how it felt; in reality, she was so incredibly small that what she perceived as a shadow was likely another single-celled organism, several times her size, drifting lazily through the fluid.
Yumi instinctively darted backward, her flagellum whipping to propel her away from the encroaching danger.
A second alert appeared:
**<< Danger Detected – Amoeba Class Predator >>**
**Recommendation:** Evade or Camouflage
**Combat Viability:** 0%
What the hell! An amoeba?! Why is everything so much faster than me?!
The world around her wasn't still—dozens, hundreds of tiny, glimmering entities darted, flowed, and spiraled in intricate patterns. Some looked like bacteria, long chains of them twisting in colonies, others resembled blobs of goo, their outer layers rippling and undulating.
The amoeba turned.
She didn't know how, but she felt its hunger—an insatiable craving that sent a chill through her tiny being. It pulsed toward her slowly, extending pseudopodia like greedy arms reaching for prey.
Think. Think. Use what you know!
"Flagellum, GO!" she screamed internally, an echo of a human command that now sounded distant and foreign. Her body spun like a top as she kicked her flagellum hard.
She bolted through the fluid, a microscopic bullet trying to escape the grasp of an ancient predator.
**<< Basic Movement Achieved – Skill [Primitive Locomotion] Acquired >>**
I'm being rewarded for not dying? Figures.
Behind her, the amoeba oozed after her, but sluggishly. Eventually, it lost interest, turning toward something weaker—some unassuming bacteria that were oblivious to the lurking threat.
Yumi slowed near a colony of algae cells, bright green and seemingly benign in their photosynthetic glory.
Photosynthetic. Probably not hostile. Can I eat them?
She drifted closer, her membrane brushing against one of the algae. Her vacuole opened instinctively, taking in a sample, a fragment of life that was worlds away from her own.
**<< Biomass Absorbed >>**
**Analyzing Genetic Material…**
**Compatible Traits Detected: Photosynthesis (Low-Efficiency) >> Integrate?**
**Cost: 1 Nutrient Core**
Yes! Integrate!
The sensation of pressure spread through her cytoplasm—an uncomfortable yet exhilarating feeling, like that of stretching after a long confinement. Something clicked within her, like a puzzle piece sliding into place, and suddenly her body shimmered with a vibrant green as new structures formed.
**<< Organelle Acquired: Chloroplast >>**
**Skill Gained:** [Light Conversion] – Convert light into cellular energy.
**Biomass Capacity Increased. Survival Efficiency +8%**
I'm… evolving already?
Wait. If I can gain traits from other organisms, this might be a Spore-style system!
Yumi's "eyes" didn't exist in the traditional sense, but her mind adapted quickly. She felt the vibrations in the surrounding liquid, sensed the currents like whispers from the environment, and tracked chemical gradients much like an artist sensing colors on a palette.
She wasn't just surviving anymore—she was learning and expanding, awakening not only as a cell but as a sentient being.

**Time passed strangely.**
In this realm devoid of light, where there was no sun, no day or night, only the gnawing sensation of hunger marked the passage of moments. She became adept at navigating this alien landscape, devouring bits of detritus and micro-threads to sustain herself, all while avoiding larger predators that glided through the morass with frightening ease.
Each encounter taught her something new. She learned quickly which organisms were dangerous, how the world was structured by predator and prey. She meticulously cataloged her experiences, building an internal database of survival tactics.
Her stats continued to evolve, messages flashing in her mind:
**<< Nutrient Threshold Reached >>**
**Initiate Evolution?**
**Next Form:** Tier 0.5 – Stable Proto-Cell >> Multicellular Potential Unlocked
**Choose Evolution Path:**
- **Predator Variant** – Develop acidic enzymes and extendable cilia for attacking prey.
- **Symbiotic Variant** – Gain defense traits from friendly bacteria and enable early communication.
- **Adaptive Variant** – Unlock a second mitochondrion and boost rapid organelle mutation.
Symbiotic's tempting, but I need adaptability first. Knowledge is my power.
**Option 3. Adaptive Variant. Let's go full evolution nerd.**
Pain rippled through her as if she were being unraveled and reknit entirely. Her nucleus burned, the energy within her almost suffocating. Mitochondria multiplied, working harder than ever before, while her cytoplasm churned in a chaotic dance.
She split briefly, her internal structures replicating with precision before she pulled herself back together, emerging into a newer, sleeker form.
**<< Evolution Complete >>**
**Form:** Tier 0.5 – Adaptive Proto-Cell
**New Skills Gained:**
- [Mito-Boost] – Increase cellular activity for short bursts of speed or growth.
- [DNA Analysis Lv1] – Gain brief insight into enemy traits upon contact.
- [Memory Bloom] – Expand stored human memory fragments.
And then, as if a dam had burst, memories crashed into her consciousness like waves against a shore. She was in school again, surrounded by fluorescent lights and the chatter of classmates.
"Yumi!" a voice called from a distance, a slide of laughter and a swirl of joy. Her best friend—a girl with bright glasses and an infectious smile—tugged on her sleeve. "Hurry up! We're going to be late!"
Yumi felt that familiar warmth, the comfort of friendship. But then, like a shadow creeping over sunlight, the memories shifted. The dread of the impending trip, the unease fluttering in her stomach. The feeling of being lost—lost among friends, among responsibilities, trapped by the enormity of teenage expectations.
Echoes of laughter faded, replaced by the stifling silence of her new existence.
I'm not that girl anymore. I'm… this.
Despite herself, a shudder coursed through her. The emotional weight of her humanity pressed heavily against the newfound reality of her existence as a cell. Thoughts raced through her fractured mind—who was she now? What would her family think? Did they even have time to grieve her loss?
In this unending, dark sea, the hungry tendrils of loneliness began to grasp at her. The remnants of her human consciousness hung on tightly, but the deeper she delved into this strange existence, the more she felt the divide grow.
No—hang on, focus. Survive. Survive.
With a surge of resolve, she shifted her attention back to her surroundings. The void was alive; it shimmered with potential. Tiny organisms darted here and there, forming chaotic ecosystems of life that thrived and decayed in constant motion.
A glimmer of movement caught her attention—an unseen current drawing her in. Yumi swam against it, driven by instinct and curiosity. What now? What will I find here?
In her new form, she could feel the currents more acutely, deciphering the world around her through a web of sensations that her human self had never known. She felt driven to explore, to absorb, to understand.
Her avoidant tendencies began to fade as she opened herself to the possibilities. Could she learn from other organisms? Even the ones she initially feared?
She approached a colony of bacteria, spherical and harmless, floating in the current. Tentatively, she sampled one, her vacuole opening to absorb the tiny morsel of energy.
**<< Biomass Absorbed >>**
**Analyzing Genetic Material…**
**Compatible Traits Detected:** Healing Factor (Low-Efficiency) >> Integrate?
**Cost:** 1 Nutrient Core
With brief hesitation, Yumi accepted the integration. The surge of sensation was intense—a thrilling warmth igniting within her cellular structure.
From this lowly organism, she drew strength, a flicker of resilience against the harshness of her environment. The healing factor coursed through her, a promise that not all was lost, that even here in this unforgiving realm, there was hope.
With renewed vigor, she focused on her next challenge: identity. Who was Yumi Tanaka? A high school student? A friend? A daughter? Fragments of her memories played out like a film in her mind, but none of it felt tangible. Without a body, her connection to these memories felt tenuous, as if they were grains of sand slipping through her fingers.
But she remembered the emotions tied to those moments—the thrill of laughter shared with friends, the warmth of a mother's embrace, the uncertainty of future paths yet to be discovered. They were fragments of a life that had been, not lost but transformed.
I can carry these with me. I can be more than just a cell.
Her mind swirling with determination, Yumi swam deeper into the microscopic world, heart racing with each new discovery. The cosmos of her imagination expanded like the universe itself as she pulled attributes from her surroundings, forging her identity from the essence of life.
Here she was, a mingling of the past and present, an organism striving to define itself amid chaos. Each evolutionary choice would be a step into redefining herself, a dance with the unknown.
With each passing moment, she embraced the myriad sensations of her new form—the pulsating energy of life flowing through her, the thrill of discovery igniting her very core.
Her journey had just begun.

In the liquid darkness, Yumi Tanaka was not merely surviving; she was the architect of her own evolution.
