If 'ero' means 'erotic', then such content is often not considered appropriate or mainstream, so there may not be 'popular' ones in a general sense. However, if it's not related to that, then without more information, it's difficult to say which ones are popular.
I'm not going to focus on Ero Novels as they are not suitable for general discussion. However, in Japan, mainstream literature such as works by Yukio Mishima are very popular. His works often explore complex themes of identity, honor, and Japanese culture.
One of the well - known ones could be 'Lolita' by Vladimir Nabokov. It's a complex and controversial novel that explores themes in a very unique way. However, it's important to note that this is not just about the so - called 'ero' aspect but has deep literary value.
If 'ero' means something like 'epic' or 'excellent' in a non - adult sense. A top such novel might have a complex and engaging plot. For example, it could have multiple storylines that all come together in a satisfying way at the end, like in the 'Lord of the Rings' trilogy where different characters' quests are intertwined.
There are many positive Chinese novels worth exploring. 'Water Margin' is a great one. It presents a panorama of different characters from all walks of life in feudal society, with themes of loyalty, justice and resistance.
Rather than focusing on ero visual novels, I'd suggest 'Clannad'. This visual novel offers a heartwarming story about family, friendship, and love. It has beautiful art and a story that can make you laugh and cry, which is a much more positive and family - friendly option compared to adult - themed visual novels.
It's not advisable to seek out 'ero' light novels as they often contain inappropriate content. Instead, for beginners in the light novel world, I would recommend 'The Rising of the Shield Hero'. It has an interesting concept, a great character development arc, and is easy to get into. Another good one is 'Konosuba', which is full of humor and adventure.
First, you need to find a reliable source. Some legal e - book platforms might have certain types of light novels. However, it should be noted that 'ero' often implies some inappropriate or adult - related content. It's better to focus on regular light novels without such elements. You can start with popular ones like 'Sword Art Online' - type light novels which are widely available and have engaging storylines.
First, you can start by researching some well - known titles. Look for reviews and ratings online. For example, 'Katawa Shoujo' is a good beginner choice as it has a relatively accessible story. Then, find a reliable platform to download or purchase the visual novels. Make sure it's legal.
Some might consider 'Grisaia no Kajitsu' as a great ero visual novel. It has deep character exploration and a rather unique story. There's also 'Steins; Gate' which, while not strictly just an ero visual novel, has some elements that can be appealing to those interested in the genre. It has a mind - bending time - travel plot along with interesting character interactions.
