As of the latest chapters I've read, Megumi is still alive in the manga. Usually, such major character deaths are significant plot points and would be well-publicized if they occurred.
Typically, megumi fanfic often focuses on his personality traits. His stoicism and determination are often highlighted. For example, in many fanfics, his unwavering resolve in the face of danger is a central theme.
Well, Megumi's story in the manga was full of twists and turns. She had to overcome various obstacles, and there were also some unexpected developments in her relationships with other characters.
Nope, Megumi is alive. The author has chosen to keep Megumi's character alive to continue developing their story and interactions within the manga's world.
Well, a common trope in Bakura and Ryou vampire fanfiction is the struggle between their human and vampire selves. Ryou, being more in touch with his humanity, may try to resist the bloodlust that comes with being a vampire. Bakura, perhaps having a more tenuous connection to his human side, could either encourage or mock Ryou's attempts. This internal conflict can lead to a lot of character development. Moreover, the relationship between them can range from a master - servant dynamic, which is quite popular, to a more equal partnership, depending on how the author wants to portray their bond.
