Notable Attacks/Techniques:


- Mystic Eyes of Death Perception (MEoDP): MEoDP allows Shiki to "perceive death" in the form of lines and dots. These lines lead to the ultimate destruction of anything if he traces his knife through them. Cutting the lines "breaks" the object and the parts cannot be reattached or healed by any way. He can also kill anything, both animate and inanimate by stabbing their dot of death. Whatever Shiki pierces is getting permanently erased from existence in a way that cannot be overruled. This ability can extend to more abstract things like when he "killed" the poison or destroyed Roa's soul possessing him. When Shiki kills something his body goes into semi-intangible mode, not really usable in combat, but a certain albino's power is not gonna work :maybe Although using MEoDP does strain him. Killing objects with powerful complicated existence or attempting to kill more abstract things are dangerous thus may overload his brain. Lastly Shiki cannot kill beings whose deaths he cannot understand. 

- Nanaya Mode: Shiki possess a dark alterego called as "Nanaya Shiki". He lost his memory 8 years ago and Nanaya is the representation of his past as a Demon Hunter. Although it never truly surfaced as a distinctive personality Shiki at times overcame with a strange pulse that drove him towards killing. At this state his physical abilities and fighting skills increase drastically to make him the "perfect killer". Later he learned how to control this feeling and consciously use Nanaya Mode although the fear of once becoming a psychotic killer remained. In Melty Blood Nanaya exist as a separate individual created by TATARI from Shiki's fears.

- Mystic Eyes of Purity: To see the things that are not supposed to be seen. Shiki can feel to presence of something not human just by looking at them. It also often leads for his dark Nanaya alterego to awaken and attempt to kill that being. Also allowed Shiki to perceive Tohno Akiha's Origami, when Akiha herself could not see it for herself. Its unique characteristic eventually allowed Shiki to acquire Mystic Eyes of Death Perception after a near-death experience.

- Sensou (Flash Dash): Nanaya clan secret art that allows Shiki to momentarily pass the natural limits of his speed.Used for assassinations to disappear from sight and catch the target off guard. Sensou also allows Shiki to run on or leap off from walls with ease.

- Sensa (Flash Sheath): Another Nanaya killing technique. Sensa involves quick draw and high speed slashing movements to perform insanely fast slashes. Shiki managed to cut Arcueid 17 times before she could even react.
