What they share
Both films are directed by Yoshiaki Kawajiri, and they both carry the neon soaked mood tag, and they sit in Action / Animation / Fantasy / Horror territory. If that's the register that drew you to Demon City Shinjuku, the second film will land in a comparable space — through a different lens.

What Vampire Hunter D: Bloodlust is
Moonlit forest roads, a lone motorcycle. A dhampir and bounty hunters pursue a kidnapped woman. Yoshiaki Kawajiri directs this anime horror fusion.
