Mei of the Mazoku clan

her gurdian

gifted with a small dragon statue to watch over her as a guardian spirit.

this depends on the role play but it may appear stone and she can ask it for advice.
may appear as a real small dragon like a pet
(im also very open in doing rps where your character is the guardian and after years of not communicating he finally shows himself to her and they fall for each other or something idk sounds so cute )

weapons

oni mask- doesn't have any special abilities but its a perfect staple to her silvery hair. its also adorned with little golden bells that chime only when she has a big rise of emotion, wether it be anger, sadness, or joy.

spirit fan miss Daitan- a white fan with crimson and golden intricate design. with in it was a rogue spirit of a local who came to the bath house looking for vengeance only to be met by the oni goddess at the gate. it took a few hours of combat before the spirit eventually tired out and witha swift slice of her fan the goddess captured the spirit with in her fan. now the spirit and the girl have spent along enough time together that the spirit eventually became helpful pointing out upcoming attacks and providing witty banter every now and then.

samurai sword- Mei owns one enchanted sword, hand crafted by her uncle in his best glory days she stole it whilst escaping his temple during a very heated clan meeting. now forming a new connection to the little goddess it refuses to work for any one but her.
-swords powers-
communication like her spirit fan
traps the souls of those it strikes (yokai, human and other)
cant harm other oni from its clan but can refuse to work entirley as anything other then an avarage sword (which cant hurt an oni)

powers

invisibility
shape shifting (human, oni, half of each)
spell casting- she can do a few minor spells but is constantly on the search to learn more
weather manipulation - less so manipultion and more so changes with her mood (has yet to gain control over it)
clairvoyance-An oni is capable of observing everything around them for a great distance in their mind by focusing on it. The range of this ability is increased when they open their third eye.
super strenth & agility
super telepathy- move most anything from a tea pot to helf of a mountain with nothing but her mind
electrokinesis- An oni was able to purposefully disable electronics, including the computer system on three skydivers parachutes to cause the failsafe to the reserve parachutes to fail. The oni was also able to change a stoplight from red to green while ensuring that the opposing light also remained green and ensure no airbags deployed in the cars involved in the accident he caused.
sedation- ability to to make people fall asleep.
Third Eye - Opening its third eye, the oni can increase its area of influence, causing disasters on a much larger scale.
Chaos Absorption - An oni is able to replenish and strengthen its powers by absorbing energy from the chaos it generates. The more chaos generated, the more energy it receives.

weaknesses
blood link- this a power that gets used against her by her clan that disapproves with the young oni's sense of nurturing and calmness. (only would be used during a big plot point that may involve a fight against her and her uncle or other member of her clan (or along those lines))
