A plot could involve the characters being aware that they are in a New Game Plus scenario. They could then try to break free from the game's usual narrative loops. For instance, Neptune might try to find a way to prevent the same events from repeating over and over again. This could lead to her trying to rewrite the game's code or find some hidden mechanic that can change the fundamental nature of their world. Also, the fanfiction could focus on how the relationships between the characters change in this new scenario. Some characters might become closer while others might grow apart due to the new challenges and opportunities presented by New Game Plus.
One interesting plot idea could be exploring an alternate timeline where the characters have different starting stats or abilities. For example, Neptune could start with enhanced combat skills and have to adjust to being more of a fighter than a strategist at the beginning. Another idea might be a fanfiction where the New Game Plus mechanic causes glitches in the game world, like strange character behaviors or environmental anomalies that the characters have to figure out how to fix. Maybe in this new game plus, a new villain emerges who is specifically exploiting the glitches in the system for their own gain.
One idea could be an OC CPU who has the power to manipulate time. She could use this power to try and prevent a major war in the Hyperdimension Neptunia world. Another could be an OC CPU that is half - human, half - goddess and has to struggle with fitting into both worlds and finding her true identity among the other CPUs.
One idea could be a crossover with another popular game series like Persona. The Neptunia characters could enter the Metaverse and team up with the Phantom Thieves to fight a common enemy. They could use their unique skills, like Neptune's ability to transform, in battles within the Metaverse.
In the New Game Plus setting, the characters can have different development paths. For example, Neptune may already have some knowledge from the previous play - throughs. So she could be more confident in her decision - making, leading to a faster development in her leadership skills. She might also be able to avoid some of the mistakes she made before, which would change the way she grows as a character.
One idea could be to have the characters from Naruto end up in the world of Hyperdimension Neptunia. For example, Naruto and his friends could be transported there while on a mission. They might initially be confused by the different world with its unique gaming - based elements like the CPUs (Console Patron Units). Naruto could mistake them for some new kind of ninja clans at first. Then, they could team up with the Neptunia characters to fight a common enemy, like an evil force that is trying to disrupt both the ninja world and the Neptunia world.
One idea could be the OC male being from another dimension and having unique powers. He could team up with Blanc to fight against a new threat in the Gamindustri world. Maybe his powers are related to technology and can help Blanc upgrade her own abilities.
A good plot could be that the male OC is a lost prince from a forgotten part of Gamindustri. He doesn't know his true identity at first. As he travels through the different regions, he starts to show extraordinary abilities that are related to an ancient prophecy. This leads to various factions either trying to help him or stop him depending on their own agendas. Or perhaps he's an ordinary guy who stumbles upon a powerful artifact that gives him the ability to manipulate the very fabric of the Gamindustri world, and he has to decide how to use this power for good or bad.
The Hyperdimension Neptunia light novel is interesting because it delves deeper into the lore of the Neptunia universe. It explores the relationships between the various nations and characters in more detail compared to the game. It also has some great dialogue that really brings the characters to life. The themes it touches upon, such as friendship, rivalry, and the power of belief, are all presented in a unique and engaging way.
Perhaps in this 'Naruto New Game Plus Fanfic', the world itself is changed in the new game plus. There are new areas to explore, like a hidden underground ninja village that was previously inaccessible. Naruto and his friends set out to discover this new place, uncovering secrets about the ninja world's past along the way, and also facing new threats that lurk in these uncharted regions.
Some fanfictions might explore what would happen if a character had a different alignment. For example, if a normally good character turned bad. Or they could focus on a relationship that was only hinted at in the game and expand on it in a really detailed way. There could also be a plot where the Reapers have a different origin or motive than what was presented in the game.
First, know the world of Hyperdimension Neptunia well. Research the existing characters, their relationships, and the overall setting. For your female OC, give her a unique backstory. Maybe she's from a different dimension within the Neptunia universe. Then, think about a conflict. It could be related to the power struggles between the CPUs. Tie your OC into this conflict, for example, she might hold the key to resolving a territorial dispute. Also, add some character development arcs for your OC. Show how she grows and changes throughout the fanfiction.
