I'm not sure specifically as there could be many different takes in fanfiction. But it might be about Naruto in a scenario where amethyst flames play a significant role, perhaps in his battles or some new power he has related to these flames.
Well, start with the big fanfiction platforms. FanFiction.net is a great place to look. Just use their search function and type in 'naruto of the amethyst flames'. Another option is AO3. It has a large collection of fan works. Sometimes, Naruto fan communities on social media platforms might also point you in the right direction if they know of any specific places where this fanfiction is hosted.
Well, it could be about Naruto characters involved with black flames in some unique way. Maybe it's a story where a character discovers a new jutsu related to black flames, or perhaps it's about a villain who uses black flames to cause chaos in the Naruto world.
It's hard to say for sure without reading it, but it could be Naruto himself as he often takes center stage in fanfictions. He might be the one trying to figure out the mystery behind the black flames.
He could learn through intense meditation. Just like how he trained to control the Nine - Tails' chakra. By focusing his mind and reaching a state of inner calm, he can better direct the white flames. This would require discipline and concentration.
Well, it could be related to some ancient power or bloodline limit that Naruto discovers. In fanfiction, authors often create new backstories. So, perhaps Naruto's white flames are connected to a long - lost clan whose power was sealed away. And now, through some twist of fate, Naruto unlocks this power and the white flames are a symbol of his new - found heritage.
There might be a story where the crimson flames are tied to a prophecy. A character with the ability to wield these flames is destined to either save or destroy the ninja world. Naruto and his comrades initially suspect this character but as the story unfolds, they realize that the true nature of the character and the crimson flames is much more complex than they thought, involving political intrigue within the ninja villages and hidden secrets of the past.
One idea could be focusing on a new character who joins Team 7 and brings a fresh perspective to their adventures. This character could have a unique jutsu related to the 'flames of youth' concept, like a fire - based jutsu that gets stronger with their determination.
In some fanfictions, the Dying Will Flames might be used to represent the unwavering will of a ninja. For example, a character on the verge of death could have their Dying Will Flames flare up, giving them the strength to keep fighting or to protect their comrades. This could add a new layer of depth to the Naruto characters we already know and love.
Some characters might develop by learning to control the Dying Will Flames. This could be a difficult process, similar to how Naruto had to learn to control his chakra. Through this, they grow in strength and confidence.
