Blood Sucker: Legend of Zipangu (夜刀の神つかい, Yato-no-kami Tsukai) is a Horror-themed Japanese manga series written by Saki Okuse (奥瀬 サキ, Okuse Saki) and illustrated by Aki Shimizu.

The manga is rated M (Mature, Age 18+), due to its scenes of intense violence and nudity.

The story follows main protagonist Yusuke Himukai, on his quest to rescue his beloved Kikuri from the vampire Migiri.

Yusuke races to save her, and he fights Migiri, costing him his hand in the process.

In Jason Thompson's online appendix to Manga: The Complete Guide, he describes the manga as "super-gory horror drama", but notes that the plot is a "gripping, complicated story which unpeels effortlessly".
