Yes, you can find the Cyberpunk: Edgerunners manga. It brings the cyberpunk universe to life in a visual narrative format that complements the other forms of media related to the franchise.
In Cyberpunk Edgerunners, there might be a love story between two outcasts. One is a solo, a highly skilled fighter, and the other is a rockerboy/girl with a passion for music and a rebellious spirit. They cross paths at a seedy club. The solo is intrigued by the rocker's energy and the rocker is attracted to the solo's strength. As they get involved in the power struggles of Night City, their love becomes a source of hope and motivation for them to keep fighting and surviving.
The allure lies in their dynamic. David is ambitious and wants to make a name for himself in Night City, while Rebecca is this feisty, loyal comrade. In fanfiction, they can be put in all sorts of scenarios. They might get caught up in a conspiracy that forces them to rely on each other even more than usual.
I'm not sure who Mr. Walton is specifically in this novel as I haven't read it. Maybe he is the main male character or an important figure that has some sort of power or influence over the love story in the book.
It depends. Some elements of the Walton stories might be based on real events or experiences, but they could also have fictional parts added for entertainment or dramatic effect.
Lucy is also a favorite. Her mysterious past and her unique skills as a netrunner make her an interesting subject. Fanfictions might explore her backstory more deeply, such as her time before she met David and what led her to become an edgerunner.
One interesting concept could be the exploration of different cybernetic enhancements. In some Edgerunners fanfiction, characters might get unique and untested enhancements that give them new abilities. For example, a fanfic could feature a character with a cybernetic eye that can not only see in different spectra like infrared and ultraviolet but also hack into security systems just by looking at them.
