The Durarara novels often have complex characters. For example, characters like Izaya Orihara are full of contradictions. His actions are unpredictable, and his motives are often shrouded in mystery. This makes the novels very engaging.
I'm not sure specifically what 'Cap deage' means. It could be a very specific term, a misspelling, or something relatively unknown. It might be a proper name, a local term in a certain area or a very niche concept.
Sure. One of the notable Durarara novels is 'Durarara!! SH'. It delves deeper into the complex world of Ikebukuro, exploring the various characters' backstories and their intertwined relationships. Another good one could be 'Durarara!! Ketsu'.
Yes, they do. Their personalities and relationships in the original work are the basis for fanfiction creation. Writers often take these elements and expand on them. For example, the complex relationship between Izaya and Shizuo gives a lot of inspiration for fanfic writers to create various scenarios of their encounters.
I don't have enough information to say exactly who Cap'n Kathy is. She could be an original character created by the fan fiction writer. Maybe she's a pirate - the 'cap'n' part could suggest that - who has some connection to the wizarding world of Harry Potter.
Sure is. The original form of Durarara was a light novel. It caught a lot of attention and led to other media adaptations. The light novel laid the foundation for the story's success.
