I'm not entirely sure as the title is a bit complex. 'Kawaiikereba' might imply something related to cuteness. 'Hentai demo suki ni' seems rather odd as 'hentai' has inappropriate connotations in English, but if we consider it in a more general sense perhaps it's about having a liking despite certain elements. And 'light novel' is a type of Japanese novel, often with anime - like themes.
I'm not entirely sure specifically as there could be many different stories within this genre. Generally, 'isekai' often involves being transported to another world, 'onsen' is a hot spring, and 'tensei' might refer to reincarnation in a novel context. So it could be about a character being reincarnated in a world with hot springs.
A 'succubus ni tensei light novel' might tell a story full of fantasy and adventure. The succubus could be the main character who is on a quest. Since it's a light novel, it might have a mix of action, some comical moments, and a bit of romance. For example, she could be in a world where she has to fight against other supernatural beings while also trying to understand her new succubus identity. And perhaps she meets a group of allies or a special someone during her journey.
I'm not entirely sure as the title is rather specific and not a well - known mainstream work. It could potentially be about the concept of isekai (another world) and the idea of being reincarnated (tensei) with a sense of gratitude (kansha) within the context of a novel. Maybe it follows a character who is transported to another world and is thankful for the new experiences or opportunities this new life brings.
I'm not sure about the most popular ones off - hand. But there could be some niche works that are well - loved within the genre fans. You might need to search in specialized Japanese literature or anime - related forums to find out.
I'm not entirely sure specifically what 'suki suki visual novel' is about as there could be many different visual novels with this name. It might be a story about love and relationships, as'suki' means 'like' or 'love' in Japanese. Maybe it involves the experiences and emotions of the characters in a fictional world.
Often, websites dedicated to light novels could be a good place to start. For instance, J - Novel Club or BookWalker might carry 'succubus ni tensei light novel'. You could also check local libraries to see if they have imported light novels in their collections. However, availability might vary depending on your region.
I'm not entirely sure as I haven't played it specifically. But generally, a visual novel often has a story with different characters and plotlines. It might be about relationships, adventures or personal growth of the characters within the story world.
