Dawn's light spilled across the nursery, illuminating polished floors and the towering shadow of Big Mom pacing nearby.
Katakuri's tiny eyes opened, alert and calculating, already measuring every movement of the servants around him.
Even as an infant, he could sense Big Mom's immense Haki lingering faintly in the air.
The system pinged softly: Observation Haki detected. Growth potential: 94%.
Katakuri flexed tiny arms, feeling the subtle strength coursing through his Mochi-infused muscles.
Today was the day for advanced Mochi-Haki integration.
Tiny hands accessed his system inventory again: Mochi Mochi no Mi energy and the Bloodline Vial glowed softly.
Yesterday was preparation… today is control.
He carefully sipped a tiny amount from the Bloodline Vial, enhancing the synergy between Kaido's essence and Big Mom's own bloodline.
A faint surge of power traveled through him, stretching his infant body with resilience far beyond normal limits.
System alert: Bloodline integration: 30%. Haki growth rate +0.6%.
Katakuri's tiny heart raced with the sensation of power perfectly balanced.
He then retrieved the Mochi Mochi no Mi from inventory.
Holding it delicately, he considered the applications—stretching, hardening, forming semi-solid constructs—all techniques he had studied in detail.
Every ability, every movement, every Haki interaction… must be optimized.
Tiny hands pressed the fruit to his mouth. A subtle taste, a surge of Mochi energy, and Katakuri's control over the Devil Fruit power deepened.
System update: Mochi-Haki integration: 10%. Physical stats increasing incrementally.
Katakuri experimented carefully, stretching a small appendage of Mochi from his hand, reinforcing it with Armament Haki.
He tested elasticity, density, and retraction speed.
Even as a baby, I can optimize power… this is training.
Big Mom's shadow fell across the nursery doorway.
Katakuri's Conqueror Haki pulses were suppressed, Mochi energy stabilized to remain undetected.
She cannot sense me yet… patience is power.
Tiny movements continued: Mochi constructs forming around his fists, flexing muscles, and subtly testing the limits of Haki reinforcement.
System: Mochi-Haki integration: 15%. Bloodline synergy: 35%.
Katakuri studied the servants' subconscious reactions to his faint Haki waves.
Even the smallest pulses shape perception… influence begins early.
He imagined small combat scenarios, using Mochi appendages to block or strike, integrating Observation Haki for predictive timing.
Tiny hands moved in precise motions, translating simulations into subtle real-world applications.
Efficiency is key. Every movement is data.
A gentle coo from a servant reached his ears, but Katakuri was already analyzing posture, hand placement, and stress points.
Even untrained humans reveal weaknesses unconsciously.
System ping: Observation Haki +0.03%. Armament Haki +0.05%. Conqueror Haki +0.02%.
Katakuri's tiny fists flexed again, Mochi and Haki harmonizing perfectly.
Tiny experiments continued: forming semi-solid Mochi shapes, hardening tips with Armament Haki, retracting and reshaping instantly.
Control and timing now… power later.
Big Mom hummed from the hall, and Katakuri subtly adjusted his energy.
Mochi energy retracted into his small body, Conqueror Haki pulses almost invisible.
Observation, strategy, and patience… the foundation of a Yonko.
Tiny legs flexed, testing muscle endurance. Mochi reinforcement subtly enhanced tendon strength.
Even basic movement is training now.
Katakuri sipped from the Bloodline Vial again, only a fraction this time.
The Kaido essence merged further with his own DNA, boosting durability, stamina, and latent power.
Incremental growth ensures stability… I will not risk excess strain.
System update: Bloodline synergy: 45%. Haki growth rate +0.8%.
Katakuri's mind calculated long-term progression: Mochi mastery, Haki development, and Bloodline integration schedules.
Tiny fingers reached outward, Mochi forming a small protective sphere around him.
Armament Haki subtly hardened it, Observation Haki monitoring servant positions.
Defensive and sensory training combined… efficiency at peak.
He practiced stretching Mochi in multiple directions, retracting quickly, and forming blunt shapes to test resistance.
System: Mochi control: 18%. Bloodline stability: 48%.
Katakuri's tiny eyes glimmered with focus.
Even now, I can manipulate power at the micro level… in the future, battles will be effortless.
Big Mom's shadow moved closer. He detected her Haki subtly, masking his own in response.
She will notice nothing… yet I grow stronger every second.
Tiny movements became more deliberate: Mochi constructs, reinforced with Haki, simulating both attack and defense.
Observation Haki tracked potential counterattacks from invisible threats in the room.
System ping: Haki growth +1%, Mochi mastery +5%, Bloodline integration +50%.
Katakuri's tiny body trembled slightly as new power settled in harmony.
Balance and control first… full potential later.
He imagined complex combat scenarios: multiple angles, simultaneous offense and defense, using Mochi to immobilize and control.
Tiny hands moved fluidly, translating thought into micro-practice.
Even infants can prepare for the impossible… if the mind is mature.
Mochi constructs stretched, contracted, and hardened seamlessly.
Katakuri experimented with arm reinforcement, small strikes, and rapid retraction.
System: Mochi-Haki integration: 22%. Bloodline stability: 55%.
Tiny fingers flexed into precise motions, energy coiling like threads of power within him.
Even at this stage, practice is perfection.
Big Mom hummed again, footsteps heavy on the floor. Katakuri sensed her presence, adjusting energy to remain hidden.
Observation and patience… my greatest weapons now.
Mochi energy and Haki pulses harmonized fully, yet remained imperceptible to others.
System: Haki growth +1.2%, Mochi mastery +6%, Bloodline integration +60%.
Tiny Katakuri flexed his body, practicing semi-solid Mochi shielding, testing elasticity and durability.
Even minor adjustments today lead to dominance tomorrow.
System suggested: Next step: integrate bloodline-enhanced physicality with Mochi-Haki control.
Katakuri's tiny brain calculated timing, balance, and strain to maximize gains safely.
Tiny fists moved, Mochi extending and retracting with precise Haki reinforcement.
Conqueror Haki pulses subtly rippled, masked from Big Mom's awareness.
Even infants can wield the essence of a Yonko if the mind is prepared.
And so, the day progressed—Katakuri, infant of unimaginable potential, experimenting with Mochi powers, mastering Haki integration, and merging Yonko bloodlines, a storm gathering silently in the nursery while Big Mom remained unaware.
