Karasu's Jutsu Workshop

Name: Soundless Murder Technique
Rank: S
Type: Bukijutsu
Element: N/A
Range: 20 Meters
Description: As the name suggests, this technique is simply a soundless method of killing an opponent, usually from behind with a blade. Additionally, because the user moves silently, the attack cannot be anticipated and defended against. The user will often slit their opponent's throat, preventing any cry that might give them away. Some shinobi also opt to use a cover such as mist or even frost to rob their opponents of their field of vision and then attack them.

It is possible to detect someone using the Soundless Murder Technique so long as their Perception is equal to the user's. If visual cover is used, such as a smoke bomb or another jutsu, the target's perception must be equal to the user's own +20.

This technique, when used, attacks each person within twenty meters of the user's original position with a vicious strike causing S-Ranked damage.
Requirements: Must have a bladed weapon.

Already exists as a Kirigakure specific jutsu which can only be learned from a Kirigakure ninja.

Name: Majestic Attire: Susano'o
Rank: S
Type: Ninjutsu
Element: N/A
Range: Self
Description: By applying more control over the form Susano'o takes, the user is capable of bending it around chakra cloaks and Tailed Beasts. This allows the user to utilize their Susano'o's abilities in conjunction with the strength granted by such things as Tailed Beast Mode and Six Paths Sage Mode. It also adjusts it's size accordingly to wrap snugly around the form in question. Using Majestic Attire goes along with using Susano'o, and shares the same stats other than the ability to use it alongside a separate chakra cloak. In theory, one could apply enough control to even wrap a Susano'o snugly around their own body without a chakra cloak. It costs 70 additional chakra to cast this jutsu on top of the manifestation of Susano'o.
Requirements: GM Traditional Ninjutsu, Mangekyo Sharingan, Susano'o.

Name: Yata Mirror: Absorption
Rank: S
Type: Equipment Jutsu
Element: N/A
Range: Short
Description: The wielder of the Yata Mirror is capable of absorbing up to three of the jutsu blocked by the shield per post, replenishing the user by the amount of chakra it cost to use the jutsu originally. Senjutsu Chakra is grounded through the use of Susano'o, thus permitting the user to absorb Senjutsu techniques without harm.
Requirements: Must be the owner of the Yata Mirror.

Name: Lightning Release: Enhancement
Rank: S
Type: Ninjutsu
Element: Lightning
Range: Self
Description: By invigorating one's muscles with Lightning-based chakra, the user of this technique is capable of enhancing their speed by +100. This technique is very taxing, however, and costs S-Rank chakra every post to upkeep.
Requirements: Learn from Karasu

Name: Crow Clone Technique
Rank: C
Type: Ninjutsu
Element: N/A
Range: Can be anywhere in the same country as user.
Description: A technique that produces a clone by projecting one's own chakra towards dozens of crows. Because it uses crows as a medium, it requires less chakra than the normal Shadow Clone Technique, while still being able to perform techniques. The dozens of crows then come together to form the body of a clone. The same crows of the dispersed clone can regroup and form a new clone immediately.

When the chakra projected by the user is severed, the crows disperse, though the user is still able to continue to speak through it. When the crow clone is defeated, the crows can regroup to form a new clone immediately, or failing that, can be used to blind the opponent, leaving them open to a counter-attack.
Requirements: Learn from Karasu.
