First, CalebCity should identify the main characters. Their personalities and motives often drive the story. Then, follow the sequence of events. This includes things like the conflicts that arise and how they are resolved. Just like in 'Naruto', Naruto's goal to become Hokage is a major driving force, and all the battles and challenges he faces are part of the overall story.
Well, CalebCity might start by watching the anime carefully, paying attention to the plot development, character interactions, and the overall theme. For example, noting how the main character's goals change over time and how they interact with other characters in different situations.
Maybe it has the ability to absorb chakra. So when Naruto is in a fight against an opponent with a large amount of chakra, he can use the sword to drain some of that chakra, weakening the enemy while strengthening himself. The sword could then store that chakra for later use, like to boost Naruto's own attacks.
It could be a sword that can cut through any substance, like the Susanoo easily. Just imagine Naruto swinging it and slicing through powerful jutsu defenses as if they were paper.
Well, it really depends on the specific fanfiction. Some fanfictions do make Ichigo overpowered. They might do this to explore different storylines or just for the fun of it. For example, in some, he could have a sudden boost in his reiatsu that makes him almost unbeatable. But not all fanfictions take this route. There are also those that focus on his character development in a more realistic way within the context of the Bleach universe and don't make him overly powerful.
Well, in some fanfictions, Naruto might obtain the overpowered sword through a mysterious inheritance. Maybe it was left by a powerful ninja from the past and Naruto discovers it in a hidden cave or something.
Another aspect is prior knowledge or experience. In some light novels, the MC is reincarnated or transferred from another world. Like in 'Konosuba', Kazuma has knowledge from his previous life which he uses to his advantage in the new world, and this knowledge combined with his unique skills makes him overpowered in certain situations.
The hero might be overpowered due to some special abilities or powers he was born with or acquired. For example, he could have super strength, magic powers, or extraordinary intelligence. And he is overly cautious perhaps because he has experienced great losses in the past when being reckless. So now, even with great power, he still thinks twice before acting to avoid repeating the same mistakes.
It could be that the nature of the world in the light novel is very unpredictable. There could be hidden enemies or powerful forces that even an overpowered hero would be wary of. So, in order to protect themselves and those they care about, they choose to be cautious. For example, there might be ancient curses or prophecies that target powerful individuals like the hero. And the hero, being aware of these potential threats, acts with caution.
