Kullweet, commonly known as "Kuea" is an Edel-Raid.

Edel-Raids are an all-female species that look like Human women & can merge with Humans to become weapons bonded to them. Each Edel-Raid can only merge with one human at a time to become a weapon. To be able to merge with someone else, the original human they've merged with has to be killed. All Edel-Raids are marked with a gem that stores all their power called Elemental Gelades somewhere on their body. A normal Human girl can become an Edel Raid by having an Elemental Gelade implanted in them. These hybrids are called 'Sting-Raids' but are not as powerful as true Edel Raids. Edel Raids are also capable of using "songs", which are the equivalent of magical spells. If the Elemental Gelade is removed then they turn into normal women.

Kuea's true age is unknown due to Edel-Raids being able to live hundreds of years longer than Humans, but she looks 17-18.

Kuea is tall & has long, dark brown hair with a parted fringe, 4 spiky strands on the scalp & parted back-bangs. Her eyes are red & she has a dark skin tone, but there's no indication to what her ethnicity is.

Kuea's garnet red elemental gelades are on the back of both her hands, which she covers with a pair of black arm-length gloves. She also wears a black tube top that has a turtleneck collar & exposes her midriff, & a lavender wrap skirt that ends above her knees at the front & to her ankles at the back. On her feet, she wears a pair of thick-sole, black knee-high flat boots that expose her toes, have high-pointed knee-pads & have straps on the back that also expose the back of her legs, ankles & heels.

Kuea accessorizes with silver earrings with silver chains wrapping around the back of her head & a purple belt around her chest & arms. Kuea also owns a pink night-gown.

Kuea can't react when she's hungry, which it often. She eats enormous amounts of food, she'll eat anything, but she still keeps her slim figure. Kuea loves to battle & often jumps into fights hastily.
