Oh... It's going to be a long night.
Tsukuyomi, also known as the goddess of the moon and the divinity of night, is a Primal from Final Fantasy XIV introduced in the 4.3 patch for Final Fantasy XIV: Stormblood: Under the Moonlight. She is fought in Castrum Fluminis.
Tsukuyomi appears as a young beautiful woman resembles her human self Yotsuyu. The skin of the left half of her body is very pale white, while it is black on the other half. Her irises are of azure blue color and glowing. She has a pair of rabbit ears on her head.
She wears a traditional Japanese dress. She wields a fan in her left hand, and a pipe in the other hand.
A magical crescent is floating behind her.
Tsukuyomi shares the same minds and personality with her human self. She also smokes with a pipe.
Her battle theme consists of three parts. The first phase is called Nightbloom, featuring a remix of the iconic Stormblood track Revolutions. Starting up with powerful wind instrumentals and leading up to melancholic string and piano portions, it almost alludes a twist in the intertwined nature of Tsukuyomi's host about committed atrocities compared to a tragic past. Lunacy accompanies the second phase, using loops of piano and chords in a medium-paced, more resolved melody.
Wayward Daughter is played as the third and final phase unfolds. It features mixed female and male chorus singing English and Japanese lyrics to a more rock opera-like hymn.
Tsukiyomi-no-Mikoto (月読命) is the moon god in Shinto and Japanese mythology. The moon was considered a male deity, brother and consort of the sun goddess Amaterasu. The kanji for Tsukuyomi mean "moon" and "read".Tsukuyomi or
Tsukuyomi in Final Fantasy XIV has a pair of bunny-like ears on her head, this might be a reference to Lady Kaguya, the princess of the moon from another folklore. Another possibility is it might be an allusion to the folklore of rabbits on the moon.
