I'm not sure about its popularity. It might be popular within certain niche communities who are fans of visual novels, especially those interested in stories with female - centric characters. However, without more data on its sales or community following, it's hard to say for certain.
I'm not entirely sure specifically as I haven't fully explored it myself, but generally a visual novel is a form of interactive fiction. It might involve stories about relationships among characters. Maybe it's about different aspects of the relationships between 'kanojo' (which might mean 'she' or 'girlfriend' in Japanese).
There isn't much information available to me regarding its widespread popularity. However, if it has unique storylines, engaging characters, and good graphics (if applicable), it could potentially be popular among the visual novel community. Some visual novels gain a cult following even if they are not well - known to the general public.
I'm not entirely sure as I haven't played it in detail. But generally, a visual novel often involves a story with characters and various plotlines. It might be centered around relationships with the female characters (since 'kanojo' means 'she' or 'girlfriend' in Japanese).
One possible scenario in a Ruka and Akatsuki fanfiction could be that they team up to protect Yuki from the pureblood vampires who have some devious plans. Ruka, with her loyalty to Kaname, might initially be hesitant to work with Akatsuki but realizes they have a common goal. Akatsuki, being a skilled vampire himself, could bring his combat abilities to the table while Ruka uses her knowledge of the pureblood society to strategize.
One common theme is friendship. Since Naruto is known for his ability to make friends, in fanfictions with Ruka, their friendship often plays a central role, like in 'The Bond of Naruto and Ruka' where they support each other through tough times.
Well, perhaps in terms of character development. Just as Kazuya in some fanfictions might have complex backstories and growth arcs, Naruto also has a very in - depth character development journey. His experiences from being an outcast in the village to becoming a hero are full of twists and turns, much like how a well - written Kazuya fanfiction might explore the character's evolution.
Hard to say for sure. Their relationship has its ups and downs, and her feelings for Kazuya aren't straightforward. It depends on how you interpret different scenes and interactions.
