In some yami and seto fanfictions, Yami might be depicted as the more mysterious and powerful one. Seto, on the other hand, is often shown as the proud and wealthy character. Their interactions can range from intense rivalries to unexpected alliances or even romantic undertones. However, in lemon fanfictions, these characteristics can sometimes be exaggerated for the sake of the plot.
Another interesting concept could be a crossover fanfiction. Picture a situation where Luffy from One Piece, who has the Yami Yami no Mi in his world, somehow ends up in the Naruto world. This could lead to all sorts of chaos and interesting interactions as the two different power systems collide.
Forest-supporting land refers to the land provided for the production of forests, mainly used in the field of forest production, including the provision of engineering facilities and supporting facilities, supporting the scientific research, testing and demonstration bases of forests, as well as the land for the cultivation of seeds, the production of seeds, the storage of seeds, seedlings, wood and other means of production. Lin Fu land could also be used for the cultivation of Chinese medicinal herbs. Jixi City planned to increase the planting area of Chinese medicinal herbs from 2021, strengthen the construction of Chinese medicinal herbs bases, and build a brand of Chinese medicinal herbs. Forest-assisted land that has been included in the local basic farmland and tax area can continue to be contracted to grow crops, while forest-assisted land with a slope of more than 15 degrees and causing serious soil erosion needs to be returned to forest and grass year by year. If the ownership of the auxiliary land of the state-owned forest farm is clear and the national real estate registration certificate is obtained according to law, it can be used for compensation. Jixi City rented land from powerful and willing plantation owners through auctions to promote the rapid development of Chinese herbal medicine plantation.
To create a unique Naruto Yami Yami no Mi fanfiction, start by thinking outside the box. Don't just copy the typical uses of the Yami Yami no Mi from One Piece. Instead, adapt it to fit the Naruto world. For instance, instead of just absorbing physical things like in One Piece, the power could be used to absorb ninjutsu and turn it into something else.
One of his friends could be the cause, accidentally. Maybe a friend makes a deal with a shady character without realizing the consequences. This deal ends up putting everyone in danger, and Yami gets mad at his friend's naivete and the mess they've created.
Yami remains alive in the manga. The author chose to keep Yami as an ongoing character to drive the story forward and interact with other characters in various scenarios.
As far as I know, Yami doesn't die in the manga. The story might have twists and turns, but that particular event hasn't happened yet. Maybe there are rumors or speculations, but based on the official storyline, no.
