I'm not sure specifically as there could be many different 'arata naru sekai' light novels. It might be about a new world, as 'arata naru' can mean 'new' and'sekai' means 'world'. But without more context, it's hard to say for sure.
I'm not sure if there is such a fanfiction. Fanfiction can cover a wide range of scenarios, but the idea of Naru cheating on Keitaro goes against the main relationship dynamic in the original Love Hina series. However, in the vast world of fanfiction, it's possible that someone has written such a story, but it may not be a common or well - known one.
In 'female naru x neji fanfic', one characteristic is often the exploration of their contrasting personalities. Nari might be bold and energetic while Neji is more reserved. Another is the development of a unique relationship dynamic that may not be present in the original story. Also, there's usually a focus on their mutual growth, both as individuals and in relation to each other.
Yes, there are quite a few. You can find them on popular fanfiction websites. Just search for 'Ghost Hunt Naru and Mai kiss' and you'll get a list. Some might be more focused on the build - up to the kiss while others might have different plotlines leading to that moment.
The friends' reactions could also vary depending on their own personal experiences. If one of their friends has had a difficult pregnancy or lost a baby in the past, they might be more guarded in their excitement. They could offer more emotional support rather than just focusing on the happy aspects of the pregnancy, like Ayako who might be there to listen to Mai's fears and concerns throughout the pregnancy.
Obviously, Naruto is one of the main characters. And Kakashi's dogs are also main characters in a sense, as the story is centered around Naruto's meeting with them.
I really like 'Naru's Unexpected Encounter' which is also in the realm of 'Ghost Hunt Naru x Reader' fanfiction. In this one, the story starts with a chance meeting between the reader and Naru. It has a slow - burn romance aspect that is really sweet. The author does a great job of writing Naru's character as aloof yet gradually showing his growing feelings for the reader.
Well, it could be that Naruto is on a mission and stumbles upon Kakashi's dogs in the middle of some sort of danger. The dogs could be protecting something important, and Naruto has to work with them to keep it safe. This would lead to Naruto getting to know their unique personalities and abilities better, and perhaps even learning some new skills from observing them.
