The overflowing roar sounded just like pressure escaping a steam engine. The Dianoid’s floor shook as a massive insect slowly revealed its form. To the very top it was just below two meters tall, and it was over four meters long. Its overall silhouette resembled a scorpion with a thick arcing tail in the back.

[...]

The upper body of a man in a tailcoat grew from the tip of the large arced tail where a venomous stinger would normally be found. Needless to say, he was one of the many St. Germains. So in a way, this was essentially a bizarre version of Hamazura’s Power Lifter.

For an instant, Hamazura thought Aneri had undergone a serious error after succumbing to all the rigorous work he was putting it through.

But in reality, the creature’s estimated muscular strength was just that ridiculously high.

[...]

The four-meter flower scorpion charged forward like a shell, and the male St. Germain extending from the thick tail produced a deep sound as he swung his own body around.

[...]

But the scorpion maintained its momentum and Hamazura used his steel arms to forcibly restrain its large pincers.

With a horrid grinding noise, the Power Lifter slid backwards.
