Species: Vampire

Vampires (吸血鬼 Kyūketsuki) are among the least popular non-human creatures living in Gensokyo. They are usually self-centered, enjoy provoking strangers, drink the blood of humans, and specialize in creating disasters that affect the entirety of Gensokyo.
They are the beneficiaries of great physical enhancement as well as magical power. However, they do have several weaknesses, among them sunlight, running water, and broken holly branches.
They are kept in check by an agreement with youkai that states they cannot attack humans living in Gensokyo.
* Examples: Remilia Scarlet, Flandre Scarlet.
