Is a short apparently plant based demon without a human form. She's constantly in her Etherious Form which includes leaves instead of hair and long pointed ears which also seem to be leaves. Instead of wearing clothes grasses and leaves cover her important bits and though she has skin it is exceedingly pale and covered in a light dusting of brown freckles. Her face gives the appearance of innocence and youth... and though she is stunningly beautiful she is rather obviously not human.
Thorn Curse (荊の呪法 Ibara no Jūhō) - Through the use of several hand gestures, the user is able to create, as well as manipulate, thorns at their own will. The thorns are powerful enough to strangle and, at the same time, severely damage opponents, making such ability effective for punishment. When desired by the user, the attacking thorns can even pass through the body of the target, as well as serve as a protection for the user. What the user creates, however, is not limited just to thorns and vines themselves; they can also manipulate their own Curse Power to take the rough shape of thorny vines and use it to shield themselves from harm, and can even fire off projectiles in the same manner. Additionally, the user can create a highly destructive explosion whose core is in the shape of rose petals. Furthermore, should the user be in their Etherious Form, the abilities of Thorn Curse are augmented rather drastically; with a mere swipe of their hand, the user is able to create something such as an extremely size-augmented tree branch, one whose width alone dwarfs regular humans.
Thorns (荊, イバラ, Ibara) - The user summons a series of thorny vines from whatever surface they desire (this can be done with or without hand gestures); the thorns can vary in size, with the large thorns in particular being able to pierce through a body. Regardless of the size of thorn vine created, however, the vines still ensnare the target, rendering them immobile. Optionally, the thorns can be used as a torture device.
Rose Explosion - With a simple swipe of their index and middle fingers, the user creates a rose composed of Curse Power directly ahead of them that completely engulfs its nearby vicinity in a destructive explosion.
Prison Flower (監獄の華 Kangoku no Hana) - The user grows a large, monstrous flower covered with spikes and chains around its dark bulb, described by the user as "the prison flower which blooms in the Underworld", from the ground that can use its vines to attack targets. The flower is able to contain beings inside of its bulb.
Dea Yggdrasil (冥界樹, デア・ユグドラシル, Dea Yugudorashiru) - The user creates a massive spinning sphere from their hand from where an immense wooden beam is fired at the target.
Alegria (喜びか, アレグリア, Areguria) To make use of Alegria, the user swipes their hand, causing Tartaros' mobile fortress, Cube, to ultimately turn into a monster called Plutogrim. During the transformation process, gooey projectiles are fired arbitrary throughout the building, adhering onto anything they touch, eventually spreading across and flooding the entirety of the fortress. Anyone caught by the substance remains in a suspended state permanently, or until they're freed by someone else. It is also worth to mention that the victims of this Curse don't seem to remember being in the mentioned state once they're released.
Memento Mori (メメント・モリ Memento Mori) The user produces a dark paralytic mist around the target that envelopes them, creating a massive beam of dark spirits that reaches towards the sky. Known as the ultimate Curse and the "memory of death", this Curse was created to destroy immortal beings, as the victims of this Curse are no longer alive nor are they dead, but are simply erased, becoming nothing for eternity. To some degree, it appears that Devil Slayers have the ability to resist the effects of this Curse.
Telepathy (念話, テレパシー, Terepashī) Ixia is able to hijack mental communication and talk to those whose mental links she slips into. The original Telepathy user experiences great pain upon Ixia entering the mental link, and a deafening noise resounds inside minds of the connected people. Furthermore, Ixia is also able to telepathically communicate with everyone in Tartaros.
