Vamirio is a short, young-looking, petite woman with red hair, pointy ears, and yellow eyes.
Vamirio is very hotheaded yet cautious, often donning a scowling expression. She has a tendency to call others, including herself, stupid. Despite those traits, she cares about the well-being of the civilians in the Demon Kingdom and thus has a hard time trusting newcomers. 
Vamirio had previously voiced the opinion that the humans must be destroyed, but has changed since she met Helck. She considers friendship very valuable and would be pained to see Helck kill his old companions even if it was for the betterment of Demon Kingdom. 
She is a fan of orange juice.
