Well, Cendrillon is the central figure. Her father is also an important character though often overlooked. His lack of proper protection for Cendrillon sets up the difficult situation she is in. And the servants in the prince's castle are important too as they help in the search for the mysterious girl (Cendrillon) who left the ball so suddenly.
One of the main themes is the idea of transformation. Cendrillon goes from a poor, mistreated girl to a beautiful princess. Another theme is the power of kindness. Despite her stepfamily's cruelty, she remains kind-hearted. Also, there is the theme of fate. The fairy godmother's intervention seems like fate leading her to the ball and ultimately to the prince.
Cendrillon is a Caribbean adaptation of Cinderella. It brings a unique flavor and setting to the familiar tale, making it more relevant and engaging for a Caribbean audience while still retaining the charm of the original.
The unique character of Miku in it makes it special. Miku is a very popular and recognizable figure, and having her in a light novel gives it a certain charm.
One similar light novel could be 'The Melancholy of Haruhi Suzumiya'. It also features a unique protagonist and an interesting mix of school - life and supernatural elements. Another one is 'K-On!', which has a light - hearted tone and focuses on the relationships within a group, much like how 'cendrillon miku light novel' might have its own character relationships. And 'Sword Art Online' has a complex fictional world setting which is a characteristic that might be shared with 'cendrillon miku light novel'.
The main distinction of porn with a story genre from regular porn is the presence of a coherent narrative. Regular porn often jumps straight to the sexual action, while the story genre tries to add some kind of story framework around it. But in the end, both are adult-oriented and feature explicit sexual content.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
