It can also be used to explore different aspects of the characters. The girl in cat form might have different behaviors and instincts that play into the relationship. Maybe she's more playful or shy as a cat, and this affects how the romance develops. The transformation can also create some comical situations, like when she accidentally knocks things over in cat form, which can be a source of bonding between the characters.
The bad girl heroine in romance novels works in several ways. Firstly, she provides a fresh take on the female character. Instead of being the perfect, always - proper lady, she has her flaws and edge. This makes her more relatable to readers. For instance, she might have a quick temper or be a bit of a rule - breaker. In the context of the romance, her 'bad girl' nature can lead to some steamy and passionate encounters with the hero. She may be the one to initiate the relationship or take risks that a more traditional heroine wouldn't. And as the story progresses, her journey towards love might involve her having to confront her own 'bad' tendencies and grow as a person, which is a great arc for a character in a romance novel.
There's also 'Kemono Friends: Pavilion'. It involves a unique world where the girl - animal transformation is a key part of the story, and there are romantic undertones as the characters interact and build relationships. It has beautiful visuals and an interesting plot.
Often, she might be turned back into a human. Maybe a kind wizard or a magical spell reverses the transformation.
She probably has to adapt to moving around on four legs instead of two. Her perspective of the world also changes. Things that were easy to reach as a human are now out of reach or difficult to access.
One common theme is self - discovery. When a girl turns into a cat, she often has to learn new things about herself and her abilities. For example, she might discover new senses or ways of interacting with the world.
In otome game novels, the yandere trope often involves a character showing extreme love and possessiveness. For example, a yandere character might become jealous very easily and take extreme actions to keep the protagonist to themselves. They can be overly affectionate one moment and then turn menacing if they feel their love is being threatened.
The 'secret baby' trope usually starts with a character, often the mother, keeping the baby's existence a secret from someone, like the father. This creates instant conflict.
The 'Hermione is collared' trope in fanfiction works in multiple ways. Firstly, it can be a physical symbol of her being controlled or restricted, which might be related to a dark magic plot or a powerful enemy. For example, the collar could limit her magic or her freedom of movement. Secondly, it can also be a metaphor for her being bound by certain rules or expectations within the fanfic's created world. It can lead to interesting power dynamics, like she has to rely on others to help her remove the collar, or she has to find her own inner strength to break free.
In LitRPG Light Novels, the 'System Apocalypse' usually starts with the sudden appearance of a system. This system often brings with it new rules, like character levels, skills, and stats. For example, in many novels, people suddenly find they can gain experience points by fighting monsters or completing quests. The apocalypse part comes in as the world is usually turned upside down. Old ways of life are no longer viable, and survival often depends on how well one can use the new system.
It adds an element of adventure. When the heroine runs away, she often embarks on a journey full of unknowns. This journey can bring her and the hero together in unexpected ways. Like in some novels, they might be forced to rely on each other for survival, which deepens their connection. Also, her running away usually means she is trying to break free from some form of oppression or control, which makes her a strong and independent character. This strength and independence are attractive qualities that enhance the romantic allure in the story.
