Name: Yajirushi Hahen ('Arrow Splinter')
Rank: C
Power: D
Activation Cost: 3
Upkeep Cost: N/A
Range: 1km
Speed: Equal to the arrow fired
Element: N/A
Skill: Kyu-Ninjutsu
Classification: Clan Exclusive (Kaguya)
Requirements: Fired Arrow of Bone
Parent Technique: Hone no Yumi ('Bow of Bone')
Hand Seals: Half Tiger
Description: Before firing an arrow, the user may implant a bit of their chakra into the bone of their arrow. Once fired, as long as its within 1km of the user, they may use a half tiger seal to activate it--making the fired bone arrow splinter into many smaller pieces, spreading out the damage from one larger hit, to multiple smaller hits.
Weaknesses: No matter the user's possible firing range, even if up to 5km, they are limited to only 1km, outside this range it is too far for the chakra to be activated, and if used before on a longer shot, it'll spread out and become harmless.
Name: Hika Tanto ('Hypodermic Tanto')
Rank: C
Power: C
Activation Cost: 5
Upkeep Cost: N/A
Range: N/A
Speed: N/A
Element: N/A
Skill: Ninjutsu, Kekkei Genkai
Classification: Clan Exclusive (Kaguya)
Requirements: Shikotsumyaku level 1
Parent Technique: N/A
Hand Seals: N/A
Description: The user will push a bone out from their palm, a simple bone handle, before yanking the handle from their hand. This forms a tanto of bone, a short blade, although the difference between it and another sword is the shape. It is molded with a hollow center, essentially a large hypodermic needle with a very sharp edge. This makes it a great way to potentially inject a larger dose of poison then a simple cut may do, making it even more deadly when used in such a manner.
Weaknesses: Due to its hollow structure, it can never reach S hardness of the mastered bloodline.
Name: Hone no Hari ('Needles of Bone')
Rank: B
Power: A
Activation Cost: 20
Upkeep Cost: N/A
Range: 50m
Speed: A
Element: N/A
Skill: Ninjutsu, Kekkei Genkei
Classification: Clan Exclusive (Kaguya)
Requirements: Shikotsumyaku Level 2
Parent Technique: N/A
Hand Seals: N/A (Charge time equal to 4 Hand seals)
Description: The user will draw back their arm or arms, using their Shikotsumyaku abilities to form small, thin, but somewhat long needles of bone. These take time equal to performing 4 hand seals to form under the user's skin. In a flick of the user's arms, they will fling out these needles, launching them from their skin and towards their opponent with pinpoint accuracy and impressive speed. These themselves are harmful, as if being hit by 50 senbon at once, but the real threat is if the user is able to incorporate poisons to the needles, making it an effective transfer method of liquid poisons.
Weaknesses: The user must have the space to 'fling' their arm out, without the space or with their arms bound--they will be unable to use this jutsu.
Name: Hone no Yumi ('Bow of Bone')
Rank: A
Power: Varies
Activation Cost: Varies
Upkeep Cost: N/A
Range: N/A
Speed: N/A
Element: N/A
Skill: Kyujutsu, Kekkei Genkai
Classification: Clan Exclusive (Kaguya)
Requirements: Shikotsumyaku Level 1, Shikotsumyaku Level 3 (For S rank Only)
Parent Technique: N/A
Hand Seals: N/A
Description: The Kaguya will use their ability to manipulate their bones, forcing their spin to protrude from the base of their neck, allowing the user to grab their spine and pull it out--molded into a bow of bone, using cartilage as the string and bone for the bow itself. The user is able to vary the power of this bow to match what they are able to realistically wield, ranging from C quality, to A quality with the level 1 of the bloodline--and S after unlocking level 3 of the bloodline. All these bows have the hardness equal to the user's bones, either A with Level 1, or S with Level 3. The user's of this jutsu can only produce the higher ranked versions of the bows if they themselves can learn jutsu of that rank. C rank may use C rank version, B rank may use B rank version, and so on.
Shikotsumyaku Level 1
C Rank--The beginning phase of this jutsu, costing 5CP to form, this is a rather basic bow, equal to what you'd buy from the market.
B Rank--The next step, increasing the tension of the bow by strengthening the draw power, equal to a bow a step above what you can easily buy in the market. This costs 10 CP to form.
A Rank--The final step allowed using only the first stage of their KKG, this creates a fairly powerful bow of A rank quality. This costs 20 CP to form,
Shikotsumyaku Level 3
S Rank--This final version is only available to the Kaguya who have mastered their bloodline limit, having bones as strong as S-Rank metal naturally makes it possible for the user to form a bow of equal quality and strength. This final stage of bow-making via the user's spine costs 30CP to form.
Weaknesses: N/A
