Well, 'Densha Otoko' isn't real. It's more like a made-up tale that captured people's imaginations. The characters and events were crafted for entertainment.
Begin by choosing a character you want to focus on in your fanfiction. It could be the main character or a side character that you find interesting. Research their traits and quirks from the show. After that, start writing short scenes or dialogues that are in line with their personalities. For instance, if the character is known for being shy, write a scene where they have to overcome their shyness in a new situation.
The 'densha otoko real story' is about a man's experiences on the train. It might involve his daily commute, the people he meets on the train, and the events that occur during his train rides.
Since the title is 'densha otoko real story', 'otoko' means man in Japanese, so it's probably a man. However, without further details, we can't really say much more about him. He could be an ordinary commuter, a train enthusiast, or someone with a unique job that involves a lot of train travel. He might be a shy person who observes a lot during his train rides, or a more outgoing one who engages with other passengers.
Since I'm not sure about the exact content of 'otoko girai light novel', it's hard to say. But generally, light novels can have themes like friendship, coming - of - age, adventure, or romance. It could be any of these or something completely different.
The story setting might also be a factor. If it's set in a very unique world, with its own rules, cultures, and magic systems, that would make it stand out. For instance, if it's a world where the concept of 'Masho' is something completely new and different from what we've seen in other fantasy light novels, that would be very interesting.
I haven't read this novel specifically. But generally, it might explore the relationship between the characters, perhaps with themes of youth, identity, and unique personalities. Maybe the 'end of novel' part implies a conclusion to the story arcs of the denpa onna (a girl with some special or 'radio wave' - like characteristics) and the seishun otoko (youthful boy).
I'm not sure exactly as I haven't read it in detail. But generally, a light novel often involves unique characters, a fictional world, and a specific plot. It might be about the man (otoko) who is taken in or favored (hirowareta) by something related to kamitachi, perhaps some sort of supernatural beings or events.
