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.
Since I haven't read it, I can't tell who the main characters are.
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 entirely sure as I haven't read it in detail. But generally, it might be about the story of a bisque doll and themes related to love.
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.
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.
I'm sorry I don't know the specific main characters as I haven't read the light novel.
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.
Some popular isekai light novels include 'Re:Zero - Starting Life in Another World'. It has a complex story with a protagonist who has to keep reliving in the isekai world. Another one could be 'Sword Art Online', which has elements of being trapped in a virtual world that can be considered a form of isekai.
