tetrapod launch

Once the knights had broken the surface and climbed atop the tetrapods...
...It appeared from below and pierced through them.

The many tetrapods, each weighing more than a ton, blew away like a volcano had
erupted. The knights on them, having also been thrown upward, recovered their balance
in midair and scanned the surface below to look for a landing point.
At ground zero—the center of where the twenty-one knights and vastly numerous
tetrapods had gone flying—was a lone girl.
She had long black hair tied in the back, white skin covered in lithe muscles, a squeezed
short-sleeved T-shirt, jeans with one leg cut off, western boots, and a katana more than
two meters long called the Shichiten Shichitou resting on the leather belt at her waist.

Kanzaki Kaori.
