I'm not sure specifically as I haven't read this light novel. But generally, a title like this might be about the formation of friendship between male and female characters. 'danjo' can mean male and female, 'yuujou' is friendship, and'seiritsu suru' means to be formed.
I have no information indicating that it is popular. There are so many visual novels out there, and without any prior knowledge or data about this one in particular, it's difficult to say it's popular.
I'm not sure specifically as I haven't read this novel. But 'ore' means 'I' in Japanese, and 'parry' might imply some kind of defensive or evasive action. It could potentially be about a character who claims to be able to parry all things, perhaps in a battle or challenging situation.
Since I'm not familiar with this specific visual novel, it might be about different characters' relationships and the story might revolve around how they interact with each other in various scenarios. Maybe it focuses on the character 'kanojo' and her experiences with different people, but again, this is just speculation without more knowledge.
Since it's a light novel, 'makikomarete isekai teni suru yatsu wa light novel' is likely to tell a fictional story. The 'makikomarete' part might imply that the main character is drawn into or surrounded by certain circumstances that lead to their isekai -ification. It could explore themes like self - discovery, as the character is thrust into a completely new environment. There might be elements of fantasy, like unique powers or abilities that the character discovers in the isekai world. Also, the relationships the character forms in this new world, whether it be friendships or rivalries, could be central to the plot.
I'm not sure specifically as I haven't read this web novel. But generally, 'isekai' often involves a character being transported to another world. Maybe it's about a character who gets involved ('makikomarete') and then is transferred to another world ('isekai teni suru') in the context of a web novel.
You could start by looking in local libraries. They often have a diverse collection of novels, and if they don't have it in their physical inventory, they might be able to order it for you. Also, some specialized Japanese bookstores, either physical or online, could be a good place to search. There are also some e - book platforms like Kobo or Google Play Books that might have it available for download.
