First, give the vampire monster a unique appearance. Maybe it has long, gnarled claws and a tattered cloak. Its eyes could glow red in the dark. For its personality, make it arrogant. It believes it is superior to humans like Daphne and constantly taunts her while she is tied up. This arrogance can be its downfall as it underestimates Daphne's resourcefulness.
Chained fanfic refers to fan - made stories that are connected in a sequence. It's like a chain where each link is a different part of the story. Usually, the plot or the characters in these fanfics are related to one another in a continuous way. Maybe the first fanfic sets up a certain situation or character arc, and then the subsequent ones continue to develop that.
A chained novel is a type of collaborative writing. It's where multiple authors contribute to a single story, one after another. Each author adds a chapter or section, building on what the previous author has written. It can lead to really interesting and diverse stories as each writer brings their own style and ideas to the table.
In fanfiction, Tsukune's monster form often showcases his growth and power evolution. Writers might explore how his new form affects his relationships with the other characters, like Moka. It could be a more powerful and fearsome version of himself, with enhanced physical abilities and maybe new magical powers.
