Kekkei Genkai: Poison Conversion. This ability allows Homura to transform liquids into poison and vice versa. The poison conversion can also be done with her body fluids. (drool, sweat, blood, etc.) Which means fighting hand to hand isn't the best of ideas.
The ability also gives Homura a strong immunity to other poisons, however, it doesn't work too well when pitted against other Kugutsu poisons. Also, her poison can be turned into a gas state, and back.
Poison Jutsu:
Poison mist: Homura would make the needed hand signs before releasing a cloud of poison from her mouth that would surround the area in a thick black mist like poison.
Poison bomb: Homura would make the needed hand signs, before creating a black ball of poison in her hand in which she would throw at the enemy. Once hit by the ball, it will explode in a cloud of poison. Although it'll explode even if its block or stopped. Homura can also cause it to explode at will.
Poison shield: Homura would make the needed hand signs and would make a shield out of poison and anyone that comes into contact with the shield will be poisoned.
Poison wave: Homura would make the needed hand signs, before releasing a powerful wave of black poison from her hands. Anything caught in the wave will be poisoned and will die shortly after.
Poison clone: Homura would make a clone out of poison, however, the clone can and will explode when killed and anything caught in the blast will be poisoned.
Poison overload: A move in which Homura would create a ball of poison the size of a house and once thrown at the enemy the ball will engulf them, tapping them inside till they die. The ball won't go away till Homura runs out of chakra.
Poison spit: Homura would gather up a small amount of saliva inside of her mouth and then convert it into poison to be spat at the enemy or thrown.
Poison sweat: A move in which Homura would cause herself to sweat and once she's sweated enough, she would use her converting ability to convert her sweat into poison and whatever or whoever come into contact with her will be poisoned.
Poison body: A form in which Homura is in a state of poison. In short, she’s a floating poison cloud that can move freely about and do everything she could do before, but there’s no actual body to be seen.
