Chapter 6: A Year of Innovation
One year passed quietly within the walls of the Iwagakure medical wing. To the village, Akira was still a promising child under the Tsuchikage's eye. To Tanaka, he was a young researcher making astonishing progress. And to himself, he was simply beginning.
During this year, Akira developed two techniques never before recorded in shinobi history.
And no one but him could perform them.
Technique 1: Micro Vision Field (Kinchōgan no Jutsu)
Purpose:
A medical-focused sensory technique that allows observation of microscopic structures: cells, tissue fibers, chakra filaments — even early signs of internal damage invisible to normal medical techniques.
Development:
Akira discovered that the human visual cortex was closely linked to the chakra circulatory network around the optic nerves. By channeling a controlled, ultra-fine chakra flow into the retinal layer, he could enhance photoreceptor sensitivity.
This allowed the eyes to:
• Magnify structures down to the cellular level
• Detect micro-chakra currents inside tissues
• Observe pathogens, blood cells, and nerve damage directly
• Diagnose internal injuries instantly without physical contact
Technical Principle:
1. Chakra concentration at 0.01% output
2. Directed through the ophthalmic nerve pathway
3. Visual processing enhanced by temporal-cortex reinforcement
4. Focused by micro-adjustments of chakra pulses at 120–180 Hz
Result:
His eyes could reveal the unseen biological world — but only for brief durations due to extreme neural load.
Limitation:
The technique requires scientific understanding of cellular structures to interpret what is seen.
Without Akira's medical knowledge, the microscopic view would appear meaningless — only blurs and distortions.
Thus, the jutsu is unique to him.
Technique 2: Cellular Recovery Acceleration (Saisei Ryōkika no Jutsu)
Purpose:
A self-healing enhancement technique that accelerates mitotic cell regeneration, allowing rapid closure of wounds and stabilization of internal bleeding.
Development:
Medical ninjutsu traditionally focuses chakra outside the body to heal wounds. Akira reversed this principle: he allowed chakra to circulate inward, directly strengthening cell reproduction.
He mapped the biochemical demands of cellular reconstruction:
• ATP production
• Protein synthesis rate
• Micro-vascular repair
• Neurological signal restoration
He then created a chakra flow pattern synchronizing with:
• Blood circulation
• Oxygen supply
• Nervous system electrical impulses
Technical Principle:
1. Chakra is guided into the hematopoietic pathways
2. Energetic pulse pattern synchronized to heartbeat
3. Micro-bursts stimulate cell division in targeted regions
4. Automatic redistribution based on pain-signal mapping
Result:
Minor cuts close within seconds.
Bruised muscles regenerate overnight.
Internal injuries stabilize rapidly.
Limitation:
Requires massive knowledge of cellular behavior to avoid uncontrolled division — which could result in tumors or internal overload.
Only Akira understands the safety thresholds.
Meaning:
The technique is impossible for others to use safely.
