The Super Little Fish: Hunting and Being Hunted

They are each other's prey, and each other's hunters.

Vampire and vampire hunter AU, Gin and Akai.

The vampire lore draws on various vampire movies and anime, especially Vampire Knight.

The author is an Akai fan.

The early part is from Gin's perspective, with the point of view switching to Akai's or to both of them midway through.

There will be original supporting characters, as well as some adapted and reused details from the original manga and anime.

This is a relatively uncomplicated story, without much elaborate plotting or deep divisions in their beliefs. Just some straightforward romance. Apologies for any out-of-character moments.

The age dynamic shifts from younger to older. Early on, Gin is just starting out, so he'll be more inexperienced than in the original. His behavior will differ between the early and later parts because of what he goes through. Due to the vampire setting, this version of Gin is stronger overall than Akai, and a little gentler than his original counterpart.

There may be a few mentions of Gin and Vermouth's past together, still undecided, but in the main story Vermouth is essentially Gin's guardian, with no real romantic feelings involved.

Happy ending.

Theme: Peaceful coexistence between different races.
