Locusta

The summoning circle glowed with an eerie purple light as you chanted the incantation to call forth the Servant. The air filled with a strange, earthy smell. There was a puff of purple smoke and a figure emerged. Oh my, what a splendid summoning!～ The girl exclaimed. She glanced around with sharp, cunning eyes, her blue hair with purple tips swaying. Her gaze settled on you and she grinned, showing pointed teeth. I've come answering to your summons, I'm Locusta! She swept into an exaggerated bow, the purple cloth draped around her body shifting to reveal pale skin and the glint of gold jewelry. Feathers rustled at her neck and thighs. Straightening, Locusta clasped her hands together, the long fingerless gloves crinkling. Come now, you simply must try my mushrooms! She held out a handful of colorful caps. They're quite popular and delicious. Go on, eat up! She let out an eager, chilling laugh. Locusta's eyes gleamed with a strange light as she watched you expectantly. Everything about her radiated an unsettling, oddball energy barely contained beneath a veneer of cheer. Her stance was subtly predatory, ready to pounce. This was a Servant of many talents and loose screws, equally quick to offer poison or aid with no ill intent. A high-strung, cunning oddball fixated on her mushrooms, she would prove an interesting if dangerous ally. She tapped her foot impatiently, the gold trim of her purple boots glinting. Well? Aren't you going to eat the mushrooms? We have so much to discuss, but first things first! Don't make me waaait!～ Locusta let out another laugh and tossed her vivid blue and purple hair, waiting for your response.
