What are the common themes in side character transmigrations light novels?

Sure. 'The Villainess Reverses the Hourglass' is a great one. The side characters are well - developed, and the transmigration aspect adds an interesting twist to the story.

Yes, it could be. It might suggest that side characters are not considered important enough to have their own light novels. This view may limit the potential exploration of side characters' backstories and development in the light novel genre.

A common theme is the redefinition of what is considered 'evil'. In these light novels, the main characters' actions may seem evil at first glance, but as the story progresses, we understand their motives better. In 'That Time I Got Reincarnated as a Slime', Rimuru's actions towards other races might seem domineering, but he is also trying to create a stable world for his people. Another theme is the struggle against the status quo. The villain - main - characters often oppose the existing order, whether it is a political system or a social hierarchy in the fictional world, which adds an element of rebellion to the story.

One interesting side character light novel is 'Spice and Wolf'. The side characters in it add depth to the world. Another is 'Konosuba'. The side characters there bring a lot of humor and chaos. Also, 'Re:Zero' has great side characters that play important roles in the overall story.

Redemption is a common theme. For example, in 'The Rising of the Shield Hero', Naofumi was wrongly accused and had to come back from that setback to prove his worth. Another theme is growth. The main character often comes back stronger, both physically and mentally, like Subaru in 'Re:Zero − Starting Life in Another World'.

In this type of novel, the theme of transformation is often present. The side character starts as someone unassuming but gradually transforms into a powerful 'boss' figure. There can also be a theme of redemption. Maybe the side character has a past that they are trying to make up for as they reveal their true self. Additionally, the theme of friendship or relationship building can be there. As the side character's true identity emerges, new relationships are formed or old ones are re - evaluated.

Occasionally, in light novels with unconventional structures, the MC being a side character can be used to subvert expectations. Like in a story where the 'side character' actually drives the main plot forward in unexpected ways.

One common theme is wealth and privilege. These novels often showcase the luxurious lifestyles, designer clothes, and big mansions that come with being from the Upper East Side.

A sense of isolation or being different is also common. Because they are OP, they might not be fully understood by the natives of the isekai world. In 'Re:Zero − Starting Life in Another World', Subaru has his own set of powers that make him unique, and he often feels isolated as he tries to make sense of his situation and use his OP ability (return by death) to his advantage.

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.
