What are the common themes in light novels instead of necrophilia?

Definitely not. Light novels are mainly targeted at a wide range of readers, including young people. Incorporating such a disturbing topic as necrophilia would go against moral and ethical standards and the purpose of providing positive entertainment and literary value.

Love and bonding are also prevalent themes. The love between the caregiver and the child develops over time. In 'Yotsuba&!', we can see the strong bond between Yotsuba and her father. Additionally, the theme of learning is there. The caregiver often has to learn about childcare, like how to cook for the child, how to handle their emotions, etc.

A common theme is the battle against the unknown. Exterminators often face strange and dangerous creatures, so there's a lot of mystery and exploration involved.

In omegaverse light novels, a frequent theme is the concept of marking. This is a way for alphas to claim omegas and is a very important part of the relationship. Another common theme is the idea of scent. Scent plays a crucial role in attraction and identification in the omegaverse. Also, the theme of survival in a world where the biological differences can sometimes put characters in difficult or dangerous situations is often explored.

Another theme is power and its corruption. Many undead characters gain great power, and this power can either be used for good or lead them to be corrupted. For example, an undead sorcerer might start off with good intentions but as he gets more powerful, be tempted by darker forces.

Romance is a huge theme. The attraction between alphas and omegas is a central focus. It can be a sweet and passionate love, or sometimes a more complex and angsty relationship, especially when dealing with the social norms of the omegaverse society which might not always be accepting of certain pairings.

One common theme is self - discovery. Protagonists often have to figure out who they are in this new reincarnated form and what their purpose is. For example, in 'That Time I Got Reincarnated as a Slime', Rimuru has to learn about his new slime abilities and how he can use them to his advantage. Another theme is power - building. The characters usually start from a weak state and gradually gain strength. In 'Re:Zero', Subaru has to keep trying different things to become more powerful and change his fate. Also, the theme of building relationships is present. In these novels, the protagonists form alliances, make friends, or even find love in the new world they are reincarnated into.

The theme of friendship and teamwork is also quite common. Just like in real - world MMORPGs, characters in these light novels form parties and guilds. They rely on each other to complete difficult quests or face powerful enemies. Additionally, the concept of identity is often explored. As players interact in the virtual world, they may develop different identities compared to their real - world selves.

Another theme is self - discovery. Since they are sinners, they usually have a lot to learn about themselves. They might discover hidden strengths or weaknesses as they face the consequences of their sins. For instance, a character might find out that they have a stronger will than they thought when trying to resist the urge to sin again.

One common theme is the combination of advanced technology in a Victorian - era or similar historical setting. For example, you often see steam - powered machines and clockwork devices.
