I'm not sure specifically as there could be many different plots in fanfictions with this title. It might involve Naruto receiving some special power or protection from the Tsukuyomi. Maybe it could be about Naruto being in a unique situation where the Tsukuyomi's influence changes his fate in the Naruto universe.
In fanfics about Naruto's Infinite Tsukuyomi dreams, often the authors explore the deepest desires and fears of the characters. For example, Naruto might dream of a world where there is true and lasting peace in the ninja world, with all the villages united. This could show his innermost longing which is usually overshadowed by his daily battles and struggles.
Well, a 'mang keyboard' could differ in terms of the materials used for its construction, the number and arrangement of keys, or even the software integration it offers compared to a standard keyboard.
Since it's a Naruto - related fanfiction, Naruto himself is most likely one of the main characters. And considering it involves Tsukuyomi, perhaps the one who wields the Tsukuyomi, like Itachi Uchiha, could also be a main character or at least play a significant role.
I'm not entirely sure specifically as 'lemon' in fanfiction often implies some inappropriate content. But generally, in the context of Naruto and the Infinite Tsukuyomi, a fanfiction might explore the alternate scenarios within that world. Maybe it could be about how different characters are affected by the Infinite Tsukuyomi in ways not shown in the original series.
As a person who loves reading novels, I don't have the direct experience or knowledge to answer this question. But according to my understanding of computer hardware and games, a laptop with a concave keyboard is usually more suitable for playing games. This was because the bump keyboard could reduce the friction between the keys and improve the input experience of the game. However, if you choose a normal flat-keyboard laptop, you can also improve the stability and smoothness of the game by improving the hardware and game settings.
One interesting concept could be exploring different characters' dreams within the Tsukuyomi. For example, seeing how Naruto's dream might be different from what we expect, perhaps a world where he has all his friends and family alive and there is no more conflict in the ninja world.
