Introduction
Feat in Question

Calc
Serafall was stated to be capable of destroying Japan in a few minutes with only a "Sparkling", which in turn means she can destroy the country with a mere fraction of her powers. Easy calc, but was not mentioned at all.

This page has everything i want for this calc.

Area of Japan = 377973000000 m^2.

Let's treat Japan like a sphere.

Area of sphere = 4 × π × r^2 = 377973000000 m^2.

R^2 = 3.007813565e10 m^2.

R = 173430.4923 meters.

Diameter = 346860.9846 meters.

Since it was stated to be a few minutes, i'm gonna assume 3 minutes.

Timeframe = 180 seconds.

Speed = 346860.9846/180 = 1927.00547 m/s.

Now, to find the mass, we need to find both the volume and density first.

Volume of sphere = (4/3) × π × r^3 = 2.185068116e16 m^3.

Density of rocks = 2.65e-3 kg/m^3.

Mass = 2.185068116e16 * 2.65e-3 = 5.7904305074e13 Kg.

Finally, it's time for kinetic energy.

K.E = 1.07509e20 Joules = 25.7 Gigatons of TNT.

HOWEVER, She was stated to do this feat with only a sparkling, or a fraction of her powers, and so, according to the rules of this wiki, we multiply this value by 120 to know Serafall's true potential.

K.E = 3.1 Teratons of TNT (Small Country level)

Conclusion
Serafall's Sparkling = 3.1 Teratons of TNT (Small Country level)
