A grand noise rang out.

Mugino had circled around the model cockpit in an instant and kicked Hamazura squarely in the gut. That one attack was not the end of it. 7 or 8 of those sharp and heavy strikes sent deep pain to even Hamazura’s internal organs.

[...]

The inside of his body was shaking unnaturally. His organs were acting oddly. They felt like a living thing wriggling around inside a leather bag. That was the first time Hamazura had ever known a human body to work like that.

(They’re still in their proper places, right? …They haven’t gotten all shuffled around, have they?)
