Morning light crept into the nursery, casting long shadows across the polished floors.
Katakuri's tiny eyes opened, alert and calculating, scanning the room with the focus of someone far older than his infant body suggested.
His arms flexed subtly, testing muscle control while sensing the latent Haki still humming beneath his skin.
The system chimed softly: Observation Haki detected. Growth potential: 93%.
Katakuri smiled faintly, feeling the familiar surge of potential flowing from both his Big Mom and Kaido bloodlines.
Today was different. Today, he would begin using the tools in his system's inventory.
Patience has taught me enough… it is time to awaken the next stage of power.
Tiny hands reached out, and the system interface appeared before him in translucent light.
Inventory:
Mochi Mochi no Mi: Stored
Bloodline Vial: Kaido essence
Tutorial Guide: Active
Katakuri's fingers brushed the virtual Mochi Mochi no Mi icon. The energy pulsed faintly, almost calling to him.
It is mine… but careful planning is necessary. I will not waste this potential.
First, the Bloodline Vial. Katakuri selected it carefully, analyzing his own body stats in the system.
Combining Yonko bloodlines now, even partially, will accelerate Haki growth, physical durability, and latent Devil Fruit potential.
Tiny hands clutched the vial, and a faint glow illuminated the room.
A low hum filled the air as the Kaido blood began merging with his own Big Mom lineage.
Katakuri felt a rush of power, an internal expansion of strength and stamina, though his body remained tiny.
System notification: Bloodline integration: 15% complete. Haki growth rate increased by 0.5%.
He monitored his internal stats carefully, watching for strain or instability.
Even as an infant, I can control this. Patience… always patience.
Next, the Mochi Mochi no Mi. Katakuri extracted it from his inventory.
The energy radiating from the fruit was palpable, warm and alive.
I've studied every technique, every weakness, every application… I know what to do.
Tiny hands wrapped around the fruit, and he brought it to his mouth.
A sip, a taste, and the latent energy surged into him.
Katakuri felt his body responding immediately, Mochi energy intertwining with his dual bloodline.
System alert: Devil Fruit consumed. Energy stabilizing. Haki potential +0.2% XP bonus.
His tiny limbs stiffened slightly as his body adapted to the Mochi Mochi no Mi's power.
This… this is only the beginning.
Even at infancy, Katakuri could sense the subtle changes.
His skin carried a faint elasticity, a soft but undeniable Mochi energy flowing beneath.
Control is key… I will train in small bursts to avoid detection.
Observation Haki pulsed faintly, allowing him to monitor the servants moving around the room.
Tiny Conqueror Haki waves flickered beneath the surface, masked carefully from Big Mom's awareness.
Armament Haki strengthened his muscles subtly, giving him more resilience.
Every moment now is opportunity. Every breath, every motion, every pulse… growth.
Katakuri experimented cautiously with Mochi abilities: stretching a finger, observing the elasticity, forming a tiny semi-solid shape.
Even minimal movement now trains muscle and Haki simultaneously.
The system displayed: Mochi control: 12% mastery. Growth rate increasing.
Big Mom's shadow fell across the nursery doorway as she approached to check on him.
Katakuri froze, his tiny body still, and instinctively suppressed his Haki output.
She cannot sense the full power yet… patience…
The servants moved to feed him again, unaware of the subtle aura of Yonko blood and Devil Fruit energy in the room.
Katakuri's mind calculated every interaction, every potential risk.
Even as a baby, observation and timing are everything.
A small experiment: he focused on his Mochi abilities, shaping a tiny appendage of sticky energy around his hand.
The system displayed feedback: Mochi Haki integration: 5% efficiency. Physical strain negligible.
Tiny giggles escaped him, though his mind remained sharp and calculating.
This is not play. This is training.
Katakuri's first real test: tiny arm extended, Mochi forming a soft shield, Armament Haki reinforcing it.
System: Durability increased 1%. Observation Haki +0.02%.
Even at this stage, I can test defensive applications safely.
Tiny fingers tapped the system interface again, reviewing tutorials on Devil Fruit combat and bloodline synergy.
I already know every technique… now it's about mastering application in my body.
The Bloodline Vial's influence surged slightly as Mochi energy and Yonko DNA interacted.
Katakuri felt resilience, latent speed, and durability increasing beyond normal infant limits.
Strength grows faster than expected… careful calibration necessary.
He focused on Observation Haki, sensing subtle changes in the servants' movements and Big Mom's distance presence.
Even hidden Conqueror Haki gave him the faintest feedback from the environment.
Tiny limbs stretched and contracted, testing Mochi elasticity.
System: Mochi-Haki integration: 8%. Bloodline synergy: 17%. Physical stats increasing.
Katakuri plotted his next experiments: minor manipulations of Mochi to reinforce his infant limbs, early conditioning for future combat.
Patience… power grows in controlled increments.
Big Mom's low humming voice echoed down the hall, signaling her approach.
Katakuri's Haki pulses were suppressed, Mochi energy dormant enough to remain undetected.
The system pinged: Environment safe. Proceed with cautious training.
Tiny arms flexed again, Mochi semi-solid forms extending and retracting as he refined control.
Even small adjustments now build precision for later mastery.
Time passed slowly but effectively. Katakuri experimented with Mochi, bloodline synergy, and Haki control.
Every second is efficiency. Every observation is data. Every pulse of power is preparation.
Servants bustled, Big Mom's presence loomed, and the nursery remained chaotic.
Yet Katakuri operated calmly, mind sharp, energy controlled, growing steadily.
System: Haki growth +0.4%, Mochi mastery +3%, Bloodline integration +20%.
Katakuri's tiny hands clenched, flexed, and tested Mochi elasticity repeatedly.
Strength, control, durability… every attribute increases in harmony.
Tiny Conqueror Haki ripples tested the servants' subconscious awareness, nothing overt, just subtle confirmation of his latent dominance.
Even as an infant, I influence the world around me without revealing everything.
Mochi energy and bloodline synergy flowed through him, building resilience, speed, and latent attack potential.
One day soon, I will awaken fully… and the world will have no idea what is coming.
Katakuri lay back, tiny eyes glimmering with focus, Mochi and Haki coalescing in perfect harmony.
The first true day of power had begun. Infant to the world, but a Yonko reborn, experimenting with his birthright—Mochi powers, Kaido blood, and Big Mom lineage—ready to grow into unstoppable dominance.
