Shintai Seiatsu

Shintai Seiatsu (神体制圧, literally meaning "God-Body Control") is the "original" Kekkei Mōra acquired by Kaguya Ōtsutsuki after she had consumed the Chakra Fruit of the Shinju. It allows the user a variety of abilities, many of whom were passed down the bloodline as Kekkei Genkai, which are all associated with the power of total control over one's physical body and mental awareness — including skeletal system control, hair manipulation, and even will materialization.

Will Materialization
Kamigakari (神憑, "God Possession")

Dead Bone Pulse
Shikotsumyaku (屍骨脈, "Dead Bone Pulse")

Rabbit Hair Manipulation
Tokesōsa (兎毛操作, "Rabbit Hair Manipulation"). One commonly used technique are the rabbit hair needles (兎毛針, Tokehari), in which Kaguya would harden her hair strands and launch them as piercing needles.

Trivia

 * Shintai (神体) is translated as "body of the kami", referring to physical objects worshiped at Shinto shrines as repositories in which kami reside.
