If they ask for a random topic, give them a random element that isn't Sun, Flame, Water, Moon, Stone, Wind, Mist, Serpent, Insect, Flower, Beast, Love, Sound, or Thunder. If they already have a topic, give them 7-13 different forms of that breathing style. BTW, it doesn't actually have the flames in flame breathing, it's just visual effects so all breathings will really just be precise movements. Base it off of Demon Slayer. Also, all of the abilities have to be done with a sword, no punches.
