Abilities & Skills

Ash Bone Projection

All-Killing Ash Bones manifests as gray bone spikes capable of piercing a target and causing the struck material to decay into ash. It is regarded as a lethal Kekkei Mōra whose effect brings death with a single touch. 93 298

  • Ōtsutsuki Kaguya can launch a gray bone spike from her palm at range. 298
  • The technique can pierce through a target before its decay effect takes hold. 298
  • Asuma transferred the damage from a bone spike to a chakra-marked Flying Thunder God kunai; the kunai subsequently decayed into ash. 298

Bone-Spike Barrage

Kaguya can generate multiple ash bones from across her body, extending them outward in a hedgehog-like formation to attack enemies at close range. 298

  • Can be used immediately after or alongside other attacks, including Rabbit Hair Needles. 298
  • Functions as a dangerous countermeasure against direct physical attacks. 298

History

All-Killing Ash Bones is identified as one of Ōtsutsuki Kaguya's Kekkei Mōra techniques. Asuma classifies it as a ninjutsu rooted in Shikotsumyaku, alongside other high-level techniques whose foundations can be traced to lower-order bloodline abilities. 160

During Asuma's battle with Kaguya, she uses the technique repeatedly, first firing a gray bone spike and later producing a mass of spikes from her body. Although the spike pierces Asuma's fist, he avoids its lethal effect by transferring the damage to a chakra-marked kunai through his Level 13 Substitution Technique. 298

After the Immortal Tree devours Kaguya, the Ten-Tails, and Madara, Asuma inherits much of their bloodline power. His own Shikotsumyaku evolves directly into All-Killing Ash Bones. 300

Relationships

  • Ōtsutsuki Kaguya — Original confirmed wielder; uses the technique against Asuma during their battle. 160 298
  • Sarutobi Asuma — Gains the technique when his Shikotsumyaku evolves after the Immortal Tree consumes Kaguya, Madara, and the Ten-Tails. 300
  • Azure Dragon — Receives All-Killing Ash Bones genes as part of its creation through the Immortal Tree. 314

Trivia

  • Asuma compares the threat posed by his Heavenly Wood Divine Needle to All-Killing Ash Bones; both can transform targets and subsequently destroy them. 191
  • All-Killing Ash Bones is one of the Kekkei Mōra abilities Asuma identifies as having a corresponding Kekkei Genkai foundation—in this case, Shikotsumyaku. 160
