The antagonist is often very interesting. In Assassin Reborn, the antagonist might be someone from the assassin's past who has also changed or someone who is threatened by the assassin's new - found power. Their motives and methods of trying to stop the protagonist can be full of twists and turns, making them a character to watch out for.
I think the main protagonist is often one of the most interesting characters. Their journey and development usually form the core of the story.
The slime protagonist is quite interesting. His transformation from a human to a slime and his unique growth process make him stand out.
The titular greatest demon lord is definitely one of the most interesting. His journey from being a powerful and feared figure to being reborn and having to adapt is captivating.
Ezio Auditore is quite interesting. He's a skilled Assassin who has to navigate the complex politics and power struggles of the Renaissance in Italy. His character development from a young nobleman to a master Assassin is captivating.
The protagonist is surely one of the most interesting characters. As an extra reborn, they have a unique perspective on the world. They might have memories of their previous life which makes their actions and decisions different from the regular extras in the story. Also, any character who helps or hinders the protagonist's journey can be interesting. For example, a mentor - like figure who guides the protagonist in this new world, or an antagonist who tries to keep the protagonist in the 'extra' status.
Perhaps the people who interact with the reborn demon lord are interesting too. They might be ordinary folks who are unaware of his past. Their reactions to him and how they influence his new life could be very engaging. For example, a kind - hearted neighbor who befriends him without knowing his true origin.
The main character is quite interesting. His determination to collect all the swords makes him stand out. Also, the female lead has her own charm. She's strong - willed and often challenges the main character.
In Tensura Light Novel, Diablo is an interesting character. His elegant and powerful demeanor, along with his unwavering loyalty to Rimuru, makes him captivating. Gobta, despite his comical and sometimes clumsy nature, also adds a lot of charm to the story. And there's also Rimuru's teacher, who plays an important role in his early development and is an interesting figure in the overall narrative.
Power is also a very interesting character. She's a devil with a unique personality. Her self - centeredness and lack of understanding of human emotions make her interactions with other characters really funny and at the same time, quite complex. She has her own goals and motives that are not always clear at first.
Ami is an interesting character as well. She seems perfect on the surface, being beautiful and popular. But as the story progresses, we learn that she has her own insecurities and a more complex personality. She often plays a role in the relationship dynamics between Taiga and Ryuuji, adding an extra layer of intrigue to the story.
