Curses
Katsumi possesses the breath of the black dragon, known for its acidic properties. She can expel a spray of acid from either her hands or her mouth, up to about five yards. Against flesh it is not incredibly corrosive, but it does slow regeneration and hurts quite a bit. It is better at boring through earthly materials like stone and metal, though. She is immune to her own acid.

Charms
Katsumi can activate this spell to boost her willpower, decreasing the pain she feels and increasing her ability to keep pushing in dire circumstances. She can also use it to help counteract attacks on her mind, if she is aware of them.

Katsumi can activate this magic to allow her to fly or float. She can fly fast enough to keep pace with the average broom, and she has decent control over her maneuverability.

Katsumi can enhance her agility in wet environments - whether it be a body of water, a downpour of rain, etc. Her movement seems unhindered by any type of water, and even enhanced by it in some cases. She seems able to hold her breath for an inhuman amount of time.

Katsumi is at her best when she is pursuing or stalking those who are caught off guard or on the backfoot. Her agility and stamina are enhanced when she is chasing or stalking her foes. She is also able to detect the state and position of her hunting Daemons, and telepathically transfer information with them.

Crafts
The heritage of the Nishimura family is one that deeply connects itself to the ancient dragon tales of lore. As such, they worship and emulate the magnificent beings, passing this brand down through their bloodline - in exchange for some magical cursing potential. Katsumi’s brand passively increases her senses of sight, hearing, and smell to impressive levels. Because she possesses the Black Dragon tattoo, she innately makes it more difficult for adversaries to track her; her scent is weaker, she moves more silently, and any tracks she leaves are rather faint. In exchange, it is excruciatingly difficult for her to learn any Curses outside of her 'Black Dragon’s Breath'.

Katsumi has studied to learn the imposing nature of dragons, making it easier for her to influence the beings around her when she uses this spell. This makes it easier to intimidate Daemons or garner their respect, potentially even persuading them to follow her orders instead of someone else’s. This can also work on humans and vampires, but currently only in the form of a one-word command that isn’t directly harmful to the afflicted. To effect a human or vampire, Katsumi has to catch them off guard or render them susceptible to illusions in some way.
