A Musai (moo-ZY-ee; ancient Gr. Μοῦσαι "Muses") is a muse-like Wesen that appeared in "Kiss of the Muse".


When a Musai woges, their hair turns red and their skin turns shiny, bluish-green. Musai have large, deep blue eyes and long, pointed ears, similar to those of elves. The lips of the Musai secrete a psychotropic substance, making its kiss to be known as euphoric and addictive as any narcotic known to man. Once a relationship has been established and sealed with a kiss, it always ends in madness, destruction, and death. Should a Grimm be kissed by a Musai, the effects of her kiss will begin to affect them much faster than anyone else.

It's possible for the kiss of a Musai to be mistaken for the influence of a Hexenbiest. ("Kiss of the Muse")


Similar to Ziegevolk with women, Musai don't seem to try to hide the influence that they have over men. They also don't feel guilty about the death and destruction that they cause, thinking that they have done nothing wrong. They believe that a short, artistic, and passionate life is better than living a long life with untapped potential. They are passionate about art and target artists or those with untapped creative potential, such as authors or composers. They claim to be able to sense untapped power in people, which is what draws them to their victims. They normally target one victim at a time, and once their first victim ends up dead or insane after creating masterpieces, they move on to their next target. The relationship between the Musai and their victim causes the victim to become obsessive, willing to kill or die to be with her. The only way to cure the effects of a Musai's kiss is with true love.

Like many Wesen, they fear Grimms. However, they have no problems manipulating them if a Grimm falls under their influence.

Excerpt from Grimm Diaries

The kiss of the Musai is as euphoric and addictive as any narcotic known to man. And once begun, the relationship always end in madness, destruction and death...

13 January, 1889

I was called in by an artist acquaintance of mine whose name is Gauguin. The night before he had been accosted with a razorblade by another artist friend of his by the name of Van Gogh. Gauguin is worried that his friend is under the pernicious influence of a prostitute. He assigned me the task of discovering what kind of witch this Rachel was. I was loathe to discover that this trollop was no Hexenbiest but a Musai, and although she may have been Van Gogh's greatest inspiration for some time, her influence was starting to take its toll, causing him to cut off his own ear. I returned the favor and instead of taking off her clothes, I took off her head.

The Musai have been known to be great sources of inspiration to talented individuals, especially artists.

Their presence and kiss enhances the artist's inherent abilities to extreme heights. However their influence also seems to take its toll and come with a price.

An elfin-like muse Wesen with large, completely blue eyes. They unlock creative doors to those they get close to. The kiss of the Musai secretes a psychotropic substance and is known to be as euphoric and addictive as any narcotic known to man. Once begun, the relationship always ends in madness, destruction, and death.



  • The Musai appears to be based upon the Leannán Sidhe, creatures of Irish mythology who give artists the ability to create emotional works of art in exchange for the artists' devotion, feeding on the artist's life and fanatical devotion–driving the artist to madness and sometimes death.
  • Musai are named for the Greco-Roman Muses, the nine goddesses of the arts who inspire artists, but the similarity ends there, as mortals simply prayed to them for inspiration. Musai is technically a plural noun, the singular form in Ancient Greek being Romanized as "Musa."
