*Tsutako's Notes on the Symbiotic Fusion*
---
I. The Kashiwagi Anomaly
**Bloodline:** *Jūryoku Kyōten* (重力狂点, "Gravity Madness Points")
**Mechanism**: Kashiwagi cells contain **micro-singularities** (quantum black holes) in their mitochondria.
**Chakra's Role**: Chakra *stabilizes* these singularities. Low chakra = uncontrolled gravity wells = cellular spaghettification.
**Yuki's Flaw**: His transmigrated soul disrupts chakra-singularity sync. Like "a mismatched key grinding in a lock."
> *"His cells are literally eating themselves from the inside out."*

II. Konan's Paper: The Perfect Anchor
**Kamitsu (神紙, "God Paper") Affinity:**
- Her paper isn't just chakra-infused—it **folds space-time** at a microscopic level (precursor to *Dance of the Shikigami*).
- **Why It Works**:
- Paper's 2D surface area absorbs gravitational distortion.
- Origami creases act as **chakra circuit breakers**, preventing cascade failure.
> *"Her paper isn't a weapon. It's a quantum shock absorber."*

III. The Fusion: Tenchi no Kōsoku (天地の拘束)**
**The Process:**
1. **Chakra Braiding**: Konan's paper fibers weave into Yuki's bloodstream → **biological quantum entanglement**.
2. **Singularity Tethering**: Micro-black holes bind to paper folds → stability via **Hawking radiation-like chakra bleed**.
3. **Symbiotic Cost**:
- *Yuki*: Gains stability but loses autonomy (chakra now tied to Konan's emotional state).
- *Konan*: Gains gravity-warping power but suffers **entropic decay** (her cells age faster near singularities).

IV. Gravity-Infused Paper: How It Works
| **Konan's New Ability** | **Scientific Principle** |
|--------------------------|--------------------------|
| **Implosion Cuts** | Paper edge concentrates gravity → spacetime curvature tears matter apart |
| **Defensive Folding** | Creates localized event horizons → attacks "fall" into microscopic black holes |
| **Sensory Drift** | Warped space-time bends light/sound → invisibility & silence |
> *"She doesn't cut you. She makes you *fall* into a blade thinner than an atom."*
> — Hunter Captain's final words (recorded by Salamander summon)

V. The Looming Threat: Entropy
**Konan's Accelerated Decay:**
- **Symptoms**: Translucent skin, crystalline joint pain, temporary blindness after heavy gravity use.
- **Cause**: Exposure to Hawking radiation analogs from Yuki's singularities.
- **Tsutako's Warning**:
> *"Every time she warps gravity, she burns days off her lifespan. You're not saving her, Yuki. You're making her a martyr."*
**Yuki's Dependency:**
- >24hr separation → micro-singularities destabilize → **violent gravitational collapse** (5-meter radius).

VI. Hanzo's Interest: "Project Amaterasu"**
**Intel Recovered from Fallen Hunter:**
- **Goal**: Replicate the fusion to create living WMDs ("*Human Fūinjutsu*").
- **Test Subject #7**: Yuki Kashiwagi.
- **New Target**: Konan (codenamed *"Origami Primordial"*).
- **Countermeasure**: Hanzo deploys **Subject #13** — a child with *Steel Release* bloodline to "cage" gravity.

### **Epilogue: The Cost of Understanding**
Konan stared at Tsutako's notes, her fingers brushing the diagram of entangled chakra pathways. "So we're dying together. Just slower."
Yuki flexed his hand—the skin over his knuckles shimmered with Konan's paper grain. "I'm sorry."
"Don't." She folded the scroll into a crane. It glowed faintly, bending the candlelight around it. "Just promise me one thing."
"What?"
"When the end comes… we fall on our own terms."
Outside, rain drummed against the hideout like distant footsteps.
