Owari no Seraph

Humans vs. Vampires, but Owari no Seraph is much better for multiple reasons - characters are well developed, faster pacing, and there's actually equal tension on both sides of said battle. Shiki lacks many of these things. Shiki's plot is murky in comparison, and it's watching a 'losing battle' on a rural countryside hill. Despite that, people who liked Shiki will probably also enjoy Owari No Seraph for similar themes.
