In a more creative fanfic, an ancient ninja who was the originator of the Chidori technique could appear. This ninja could be brought back to life through some sort of magic or jutsu. He sees Naruto's pure heart and decides to pass on the Chidori knowledge to him, believing Naruto will use it for good.
Maybe Sasuke teaches him the Chidori in a moment of camaraderie. And for the Rasengan, it could be an older and wiser Naruto from the future who travels back in time to teach his younger self.
When I write novels, I say that I write with emotion, which usually refers to the exclamation and reflection of a certain thing or situation. In a novel, emotional lamentation is usually a kind of emotional expression. By describing the protagonist's emotional changes and feelings about a certain thing or situation, the reader can feel the protagonist's inner emotions and inspire the reader to think. Sighing was an important way of expressing emotions in a novel. It could make the readers resonate with the novel and understand the theme and emotions of the novel more deeply.
In a fanfic where Naruto knows the Chidori, it could change the power dynamics in battles significantly. Naruto's already vast chakra reserves combined with the piercing and fast - acting nature of the Chidori would make him an even more formidable opponent. He could use it in close - quarter combat situations, perhaps integrating it with his Shadow Clone Jutsu in creative ways. For example, he could have clones perform the Chidori from different angles, catching his enemies off - guard.
The story in 'Lament of Ament Graphic Novel' is likely to be a key aspect. It could be a narrative about loss, as 'lament' implies. Maybe it's set in a fictional world with its own set of rules and cultures. The plot might involve the main character's journey through grief or a struggle against some kind of injustice. The dialogue, if there is any, would play a crucial role in developing the characters and moving the story forward.
I'm not sure as I haven't read the specific 'the lament short story'. But usually, in a lament - themed story, there could be a protagonist who is going through a difficult time, perhaps a character who has lost someone or something important.
The main theme could be about loss or regret. Often in a lament, there is a sense of mourning for something that has been lost, like a relationship, a way of life, or an opportunity.
I'm not sure as the story isn't very well - known to me specifically. But it could be the children themselves, and perhaps their parents or guardians who are also affected by whatever situation the children are in.
