In my opinion, both have their merits. The anime has great animation and sound effects, while the manga allows for deeper exploration of the characters and plot. It really comes down to personal taste.
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).
Sorry, I don't have information on where to get the manga zip. It's best to look for legal platforms that offer the manga for purchase or subscription.
I'm not entirely sure specifically about 'Nazo Drama' as it could be a relatively unknown or niche concept. It might be a specific type of drama from a particular region or with a unique style. Without more context, it's difficult to provide a detailed full story.
Well, it could vary a lot. Maybe the anime sticks closely to the manga plot and characters, or it might make some changes to make it more visually appealing or fit a certain runtime.
The domestic 'Na Kanojo' differs quite a lot from the one on Manga Rock. There could be adjustments made to comply with local regulations or cultural preferences, which can lead to a noticeably distinct product.
