Ouma Strength scaling Volume 5

The blade struck the sandy soil of the park—and did not stop there, carving a seemingly bottomless chasm in the earth below, etching that fissure-like wound deeply into the ochre-colored ground. Ikki broke into a cold sweat at the sight. Stella too could shake the ground with her strikes, but Ouma's were a cut above her's. After all, shaking was a phenomenon caused by the dispersion of energy—a sign of excessive waste and imperfection in the user's magic control. A true strike of concentrated energy created no such perturbations. Where it went, it silently yet thoroughly blew everything away. That was Ouma's strike, which had cut through the earth like a knife through hot butter.

How much energy would have had he gathered, how much force and mass simulated in order to do something like that? How many hundreds of kilograms? How many thousands? He did not know, but one thing he did. His brother's strike, much like Stella's, was a brutal blow. And not one he could take head-on.
