I'm not sure specifically as there could be many different interpretations of a 'nazarick's duelist fanfiction'. It might involve duels within the Nazarick setting, perhaps between different powerful beings or characters. Maybe it focuses on a new character who is a duelist in the Nazarick world and their adventures and challenges in dueling against various foes.
Since I don't know the exact fanfiction, it could feature the main duelist character. Maybe there are also some of the well - known Nazarick residents like Albedo or Demiurge who could be involved, either as opponents, mentors, or observers in the duels.
One concept could be a crossover where a Hogwarts student accidentally stumbles into Nazarick. Maybe a Gryffindor student, full of courage, explores the mysterious and dangerous Nazarick, trying to find a way back home while encountering all sorts of strange and powerful beings. It would be interesting to see how the magic from Harry Potter's world would interact with the magic and power dynamics in Nazarick.
The situation of Nemu visiting Nazarick in the light novel is full of possibilities. Nazarick is a place full of magic and mystery. If Nemu enters, she may be amazed by the unique architecture and the powerful magic items there. She could also interact with the inhabitants of Nazarick. For example, if she meets Albedo, Albedo might be curious about her and question her intentions. Or if she comes across Demiurge, he might analyze her from different aspects to determine if she poses any threat to Nazarick. But since we don't know much about Nemu, all these are just speculations based on what we know about Nazarick in the Overlord light novel.
Harry Potter and Ainz Ooal Gown. Harry is the hero of his world, constantly fighting against dark forces. Ainz is a powerful overlord in his own right. If they were to cross paths, Harry might see Ainz as a potential new threat, while Ainz might be interested in Harry's unique magic and the prophecy that surrounds him. Their meeting could lead to a series of misunderstandings and battles, or they could end up forming an unlikely alliance against a common enemy.
We can expect a lot of things. Maybe Nemu will be intimidated by the sheer scale and power within Nazarick. It's a place that houses some of the most powerful beings in the Overlord universe. Nemu might learn about the different cultures and rules that exist within Nazarick, if she's given the chance to interact with the inhabitants.
The appeal lies in the creativity and imagination. A comic journey can take you places you never thought possible and introduce you to unique characters and storylines. It's a form of entertainment that can be both fun and thought-provoking.
Cartoon eyes could be associated with money if they are part of a popular character design that generates revenue through merchandise sales or licensing deals. For example, a cute character with unique eyes might be printed on various items and sold.
