==== Kaguya’s gravity dimension dramatically increases gravity—enough that even enhanced Naruto is briefly pinned. Some fan calcs estimate the gravity multiplier needed to restrain him at > 105 g10^5\ g105 g.

More directly relevant to speed:
* Naruto is able to move, attack, and generate visible shockwaves in this environment.
* Kaguya and Naruto are also keeping up with the ETSO expansion, which a popular calc places at 0.14c (≈ 4.2×107 m/s4.2\times 10^7\ \text{m/s}4.2×107 m/s).

If characters can react to, dodge around, or move proportionally relative to something expanding at ~0.14c, then you can argue:

vNaruto, SPSM∼0.1c (relativistic) in combat-reaction termsv_{\text{Naruto, SPSM}} \sim 0.1c\ \text{(relativistic)}\ \text{in combat-reaction terms}vNaruto, SPSM∼0.1c (relativistic) in combat-reaction terms
You could formalize this as:
* If ETSO expands radius RRR in time Δt\Delta tΔt: vETSO=RΔt≈0.14cv_{\text{ETSO}} = \frac{R}{\Delta t} \approx 0.14cvETSO=ΔtR≈0.14c
* Naruto’s ability to consistently position near its boundary without immediately being overwhelmed implies: vNaruto≈k⋅vETSO, 0<k≤1v_{\text{Naruto}} \approx k\cdot v_{\text{ETSO}},\ 0<k\le 1vNaruto≈k⋅vETSO, 0<k≤1

Even taking k=0.5k = 0.5k=0.5 (very conservative):

vNaruto∼0.07c≈2.1×107 m/sv_{\text{Naruto}} \sim 0.07c \approx 2.1\times 10^7\ \text{m/s}vNaruto∼0.07c≈2.1×107 m/s
So Feat 8 supports:
* Combat speed / reactions: relativistic (order 10710^7107 m/s) when fully amped.
