Another one might be 'Konosuba'. Kazuma is an antihero in a sense. He is not your typical noble - hearted hero. He is lazy, perverted at times, and mainly just wants to live an easy life in this new world he has been transported to, but still manages to get involved in all sorts of adventures.
In 'Death Note', Light Yagami can be considered an antihero. He starts with good intentions of creating a crime - free world but his methods of using the Death Note to kill criminals become extreme and morally wrong. His complex character makes him very memorable.
Well, it might be the antihero aspect. Usually, antiheroes are complex characters with their own moral codes that differ from the norm. In a visual novel, this can lead to really interesting storylines. They can make choices that surprise the reader and add a lot of depth to the plot.
One popular antihero could be Light Yagami from 'Death Note'. Although the series is not strictly a light novel, he has many antihero traits. He starts with good intentions of creating a better world but uses extreme and immoral methods. Another could be Lelouch from 'Code Geass'. He is willing to sacrifice many for his grand plan of changing the world.
One example could be 'Danganronpa'. It has characters with complex personalities that can be considered antihero - like in some cases. They are in extreme situations and their actions are not always morally straightforward.
Antiheroes in these light novels are more complex characters compared to traditional heroes. A traditional hero has a clear - cut path of good deeds and a set of values that are unwavering. However, antiheroes might question those values. They could be motivated by revenge, survival, or personal gain rather than the greater good. They may also use unethical means to reach their ends. In a light novel, an antihero might be a loner who doesn't care about the society's rules, while a traditional hero is all about upholding the social order.
One feature is likely a unique plot. Since the main character is an antihero, the story might not follow the typical 'good vs. evil' narrative. It could involve the antihero navigating a world full of gray areas. The light novel may also have a distinct writing style to bring out the antihero's personality, perhaps with a lot of internal monologues that show their conflicted nature.
One popular antihero light novel is 'Overlord'. In it, the main character Momonga is an antihero. He starts as a powerful but rather amoral character in a game - turned - real - world setting. Another is 'Konosuba'. Kazuma, the protagonist, has many self - centered and not - so - heroic traits at times. He is lazy and often more concerned with his own comfort than being a traditional hero.
One popular 'isekai antihero light novel' series is 'Overlord'. In it, the main character is an anti - hero who gets transported to a new world and uses his knowledge and power from the real world in rather self - serving ways at times. Another is 'Konosuba', where the protagonist Kazuma has many anti - hero like qualities as he tries to survive in the isekai world while being lazy and often more concerned with his own well - being than being a traditional hero. And 'Re:Zero' also has elements of this, with Subaru having to face his own flaws and make morally ambiguous choices in the isekai setting.
Sasuke could be a good antihero in this kind of fanfic. He already has a dark side and a complex personality. He has his own goals and is willing to go against the traditional ninja ways to achieve them. In a crossover, he could be even more extreme, perhaps teaming up with some new, more malevolent characters from another world. He would still have his Sharingan powers which could be used in interesting ways against both Naruto and the new threats introduced in the crossover.
