Description: The user forms the required hand seals to knead Katon Chakra within their chest. They then exhume a thin stream of flames about 5 cm in diameter. After traveling at least 50 meters, the user is able to cause the fire to erupt and create a massive bulk of flames (roughly 10m diameter) to cause intense damage to targets, likely killing anyone caught in the fire. This fire burns for up to four posts on flammable objects and continues to spread in all directions at 50 meters per second for four posts.
