There's Ryuzaki, who plays a significant role in the story. He's involved in the investigations related to the Death Notes.
One important character is Yuki. She has a unique connection to the Death Notes and her actions greatly impact the events in the novel. She is quite complex and her motives are not always clear at first. Another important character is Tsukuru. He is sort of in the middle of the power struggle involving the Death Notes. He has to make difficult decisions about which side to support, if any. His character development is interesting as he grapples with the morality of the situation.
Obviously, L is a very important character. He is a super - intelligent detective with unique quirks. His deductive skills are second to none, and he is constantly on the hunt for the truth regarding the Death Note. Then there's Near, another highly intelligent individual who is also involved in the events related to the Death Note.
L is obviously one of the most important characters. He is a brilliant detective with an eccentric personality. His intelligence and unorthodox methods are key to the story. Near also plays an important role. He is another highly intelligent character who is involved in the events related to the Death Note.
Definitely Light Yagami. He drives the plot forward with his actions and decisions regarding the Death Note. L is his equal in terms of intelligence and their battle is what makes the story so engaging. Misa Amane is also important. She also gets a Death Note and is in love with Light, which adds a complex layer to the story. And then there's Near, who comes into play later in the story and has his own part in the hunt for Kira (Light).
Well, one of the main plot points is the emergence of new Death Notes and new users. There are different individuals who get their hands on the Death Notes and start using them in various ways, which leads to a complex web of power struggles and moral dilemmas.
The main character is L. He is the brilliant detective who takes on the case in the novel.
John is an important character. He is an outsider in the 'brave new world' society, coming from a different background. His presence challenges the norms of this new world. Bernard Marx is also significant. He is a member of the society who starts to have doubts and rebel against the system. And then there's Helmholtz Watson, who is a friend of Bernard's and also has a more in - depth thinking about the society they live in.
I'm not sure yet as it's a new story. But it could be new characters who discover the Death Note, or perhaps some descendants of the original characters like Light or L.
I don't really know for sure. Maybe it will introduce some new characters along with some familiar ones from the original.
I think Near is one of the most interesting characters. He has his own way of thinking and investigating, and he enters the fray at a crucial point in the story. He is different from L but still manages to be a formidable opponent. Then there's Matsuda, who is a bit of an underdog among the group. His more naive and emotional reactions compared to the other highly intelligent characters provide a different perspective in the complex world of 'Death Note Light Novel'.
The protagonist, Satou, is extremely important. He is the one who gets transported to the parallel world. His abilities and decisions drive the story forward. Then there are characters like Arisa, a young girl he meets in the parallel world. She has her own unique personality and abilities, and she often accompanies Satou on his adventures.
