Well, it's a bit of a gray area. Some might argue it's unethical as it involves creating fictional relationships between different species in a way that might seem unnatural. However, in the realm of fanfiction, it's often just a creative and fictional exploration. As long as it doesn't promote harm or inappropriate behavior in real life, it could be seen as just a form of creative writing.
Often, you'll see themes related to communication. Since rats and humans don't communicate in the same way in real life, fanfiction might explore how they could understand each other. There are also themes of acceptance. The human accepting the rat as a friend or companion despite the differences. And sometimes, there are themes of transformation, where the rat might take on more human - like qualities or the human might understand the rat's world better.
For the anthro rat character, you can focus on its animal - like instincts and how it interacts with the human world. For example, it might be fascinated by shiny objects or have a strong sense of smell that helps in certain situations.
One idea could be an adventure where the anthro rat and the human are on a quest to save their shared world from a dark force. They use their unique abilities - the rat's agility and the human's intelligence.
The 'no longer human light novel' is mainly about a character's journey through life while constantly feeling detached from the normal concept of being human. It contains themes like self - loathing, the search for meaning in a world that seems indifferent, and the masks we put on to fit in.
I'm not sure specifically as I haven't read it. But generally, it might be about the last human in a post - apocalyptic world, perhaps facing challenges like survival against mutants or harsh environments.
I'm not sure specifically as there could be many different interpretations. It might be a rather dark and disturbing concept if taken literally, but it could also be a title with a more complex or metaphorical meaning within the context of the story. Maybe it's about a post - apocalyptic world where humans are being 'killed' in some sense, like their humanity is being stripped away.
Sorry, I'm not aware of the author of this particular light novel. It could be a relatively new or indie author whose work hasn't gained wide recognition yet. You could try searching for it in specialized light novel databases or forums to find out more about the author.
I'm not sure specifically as there could be many light novels with such a title. It might be about the last remaining human in a post - apocalyptic world, perhaps facing challenges like survival against mutated creatures, finding resources, and dealing with solitude.
