I'm not entirely sure specifically as it could be a fan - made or less - known online novel. It might be related to the story in 'Your Name' (kimi no nawa in Japanese), perhaps a novelization or a new take on the story. Maybe it includes more detailed character backstories or different plot developments compared to the movie.
The Armored Warrior Nawa was a the mainland of China fantasy action movie with a strong cast, and several of the actors were singers.
Specifically, the main roles of the Armored Warrior Nawa included the following actors:
1 Chen Feiyu: Playing the role of Yan Long
2. Li Qin: Playing Snow Eagle
3. Zhao Jinmai: Playing the role of Catwoman
4 Zhang Jingyi: Playing as a swallow
5. Wang Yizhao: Playing Black Feather
Among these actors, Chen Feiyu and Li Qin were relatively well-known singers, while Zhang Jingyi and Wang Yizhao did not appear as singers in the entertainment industry.
You could try searching on some popular e - book platforms like Amazon Kindle or Google Play Books. Sometimes, fan - created works might also be available on dedicated fan - fiction websites.
A 'Solar - Flare Rasengan'. Naruto could combine his wind - style chakra with some kind of solar - based energy he discovers. This jutsu would be like a super - charged Rasengan that emits a blinding light as well as powerful wind - based damage.
There could be a jutsu that allows for instant teleportation across long distances. This jutsu might be a new discovery in the fanfiction world, perhaps created by a character who has been experimenting with space - time ninjutsu. They might use it to quickly get in and out of battles or reach far - off places in a blink.
It could be a new form of Rasengan. Maybe Naruto discovers a way to combine different elements with the Rasengan more effectively, like adding lightning to it for a more powerful and faster attack.
I'm not entirely sure as I haven't read it yet. But it might continue the story of the main characters, perhaps showing their further development in their relationship or individual growth.
There's also the 'Inferno Storm Jutsu' in some fanfictions. It creates a large - scale storm made entirely of fire. The fire in this storm has different intensities, with the center being the hottest and most destructive. It can cover a large area, making it a great offensive move against groups of enemies.
