Miura is the Guivre of the legend – a mythical creature mostly depicted as a long serpentine creature, with wings on its back. Turns out she’s an anthropomorphic snake, living for hundreds and hundreds of years, collecting treasures and keeping them in her hidden cavern. Among these treasures, a carbuncle. Her most precious item, allowing her to be almost immortal. With it, she can absorb the matter and even the soul of humans, converting them into pure energy. The most valuable they are, the more power she can gain from them. And if it doesn’t belong to her, the effect is even stronger. Indeed, the power she’s gaining from them is much more impactful than previously used item or souls. This is the reason she’s spending countless years collecting valuable items: gold, jewels or everything valuable you can think of.

There have only been a few humans knowing about her existence, and if they were still alive, they’d all agree about one fact: the Guivre is beautiful. Miura is a gorgeous being, oozing with charm and beauty. And she got some delicious reptilian curves, her body nicely toned and the legs really thick. But she can be even more amazing than that!

The power she’s gaining from absorbing valuable items or souls is quite literal. When she's about to collect something valuable, the carbuncle attached on her neck is shining. She’s growing taller (around two meters tall), muscles bulking up in the process, greatly improving the shape of her athletic and curvy body. You could describe her new self as “Amazonian” with how tall and muscular she is now, and she remain just as beautiful. Wings are growing more majestic as well, but don’t count of them to make Miura fly like an airplane. She’d remain stuck on the ground, but you can be sure she’s capable of serious feats of strength, with how much muscles she gained. You wouldn’t want to be trapped in-between her massive thighs, feathered with stunning muscles, or neither you’d want to challenge her in arm-wrestling. Head-sized biceps are surging in size whenever she wants to flex! Don’t punch her abs either, as they can support any shock with how thick and steel-hard they are. But be aware, even at her normal size, she’s still much stronger than your average human. Oh, and I almost forgot about her... feminine attributes, as they got a nice increase in size as well.

But sadly for her, this gain in power is not permanent, as she's back at her usual form after some time. By collecting treasures and souls, she can live forever. Are you brave enough to face her?
