Another theme is the exploration of the unknown or the otherworldly. Demon and god novels usually take place in worlds that are different from our own, with different rules and magic systems. This allows the author to explore concepts such as different planes of existence, the afterlife, and the nature of the divine and the demonic. It can also be a way to comment on human nature by showing how humans react to these strange and powerful beings.
Power is a common theme. Demon gods usually represent great power, so the pursuit, control, and consequences of power are often explored.
Another common theme is the struggle between good and evil. Even though it's a demon god, there can be elements of good in it, or it might be in conflict with other forces that are considered 'good' in the context of the novel. Also, themes of redemption or damnation can be present, depending on how the demon god's story progresses.
One common theme is power - up. Naruto usually gains some form of power related to the demon god, which makes him more powerful than in the original series. For example, he might get enhanced physical abilities or new jutsu. Another theme is the development of relationships. The harem aspect means there are multiple romantic or at least very close relationships that Naruto has to navigate.
Another theme is temptation. Demons are often depicted as tempters, trying to lead humans astray from the right path. For example, they might offer power or wealth in exchange for a person's soul. In many demon novels, characters have to resist this kind of temptation.
A common theme is the power struggle. In Naruto fanfiction, characters often strive for more power, like Sasuke's journey. In Demon God fanfiction, it's about taming or using the power of the demon god. In Fairy Tail, the guild members are constantly trying to become stronger. Another theme is friendship. In Naruto, Naruto's bonds with his friends are crucial. In Fairy Tail, the guild is all about friendship. And in Demon God fanfiction, sometimes the main character forms alliances which are based on a form of friendship.
One common theme is the forbidden love. Since demons are often seen as dark and dangerous in most mythologies, a relationship with a demon is considered taboo. Another theme is redemption. The demon character may be on a journey of self - redemption through love. For example, in some novels, the demon may be trying to break free from its evil nature because of the love it has for the human or other non - demon character.
One common theme is the struggle for power. Demons often start from a relatively weak state and strive to become more powerful through various means like battles, absorbing energy or making pacts. Another theme can be the exploration of good and evil. Some demon evolution novels question whether demons are inherently evil or if they can develop a sense of morality as they evolve. Also, the theme of survival in a hostile world is quite frequent. Demons have to face not only other powerful demons but also other races or forces that may want to destroy them.
Often, there is the theme of discovery. The Demon God of Chaos may hold secrets about the origin of the world or certain magical elements. Also, the theme of transformation can be present. It could change from a purely malevolent being to one with more nuanced qualities through interactions with other characters. This makes for a more interesting and non - adult - oriented story.
Power - seeking is a very common theme. Characters in 'King of God' novels usually strive to gain more power, whether it's magical powers or combat abilities.
Power dynamics is another theme. In many sex god novels, the character's power, whether it's physical, magical or social, is intertwined with their sexual allure. For example, in some fantasy novels, a powerful wizard who is also a 'sex god' character uses his magic to enhance his charm. It also often involves themes of passion and desire, as these are central to the concept of a'sex god' in a novel. These characters are usually the focus of intense sexual and romantic desires of other characters in the story.
