The Shikotsumyaku has to do with controlling the calcium deposits on the bone of the user, and by using chakra, stimulating the growth of the bone.  Put simply, the user can extend bones through their skin, allowing for the use of their bones as weapons, forming and shaping them to their best fit.  These bones are the strongest and hardest substances known to Shinobi, and as such are very difficult to crack or break.  Users can also produce them so sharply that they form blades (details given in jutsu)

This mutation of the Kaguya clan are very different from the known branch the Canon character Kimimaro was in, and thus, the Shikotsumyaku has undergone a few mutations, with their bones seeming strange and untamed: not uncontrolled, just the visual effect of them seeming wild.  Unlike other Kaguyas, this mutation can also create joints and  move them with the same precision and control as the rest of their real body. (Obviously only for higher level techniques)

The bones of the Shikotsumyaku can resist any form of blunt force up to the strength (or estimated equivalent) of one rank above the user's END stat.  Sharpness would depend almost completely depend on this comparison of the END stat, so it would require logic to apply.  The bones can resist up to 1 rank above the END stat in Fire and Lightning Jutsu, while one full post of contact with fire can ignite them.  Anything less would simply not affect the bones.

An extension of the bone manipulation of the Shikotsumyaku, the Kaguya kekkei genkai. By further increasing the control over one's body (Rank C in Kekkei Genkai) one can begin training their Chisosa. This blood is capable of full and utter free manipulation through mitosis shifting, increasing the rate to produce more cells or literally reversing it to decrease the amount of blood present – additionally it's commonly seen used through movement control, as well as density control.

If one's blood is spilled from his body, either through trauma or by his own actions it can still be manipulated freely. But through the additional usage of neutral based chakra flow, the external usage of his blood is heightened. Allowing him to control certain unneeded traits while inside of him, such as sharpness, density, as well as elaborate construction. With or without the influence of chakra, Chisosa's external application acts very similar to Suiton but it is by no means chakra nature, or a nature transformation – classified as nothing more than an additional aspect of the Shikotsumyaku.

When someone is learning the Chisosa, they must have a BLM stat of at least C, and cannot learn jutsu who's ranks are above their BLM stat. To properly awaken the Chisosa, one must train extensively; a topic with at least 1,500 words of training would allow use of the Chisosa, but one must STILL train the techniques required to utilize it separately. Learning the Chisosa requires 500 EXP.  Note:  this is a KNOWN mutation.  Elders of the clan can recognize it by the difference in the bones.  This means that you do not need to go through some kind of miracle to discover the existence of the technique as you will most likely be told when your Shikotsumyaku is used near an older, wiser member of the clan.

If a user starts at Chuunin, they may have the option of choosing Chisosa at start. That would alleviate the Exp cost but not the training requirement.

Another example of further expansion of the Shikotsumyaku of the Kaguya, the final and highest level tier within the kekkei genkai (Rank A in Kekkei Genkai). Upon reaching the epitome of control over ones body the ability of carbon is awakened. Unlike the other forms of bodily control, this one is mainly manifested internally. By using cellular augmentation, the carbon cells are freely manipulated. Increasing or decreasing the general mass of carbon inside, as well as it's density and application – additionally it too holds certain regeneration aspects. Much like the other aspects of bodily manipulation, neutral chakra is able to be weaved into the carbon to grant further traits. Though it is similar to internal Doton usage, this too cannot be classified as a chakra nature or transformation, solely an extension of the Shikotsumyaku.

When someone is learning the Tansososa, they must have a BLM stat of at least A, and cannot learn jutsu who's ranks are above their BLM stat. To properly awaken the Tansososa, one must train extensively; a topic with at least 2,500 words of training would allow use of the Tansososa, but one must STILL train the techniques required to utilize it separately. Learning the Tansososa requires 500 EXP.  Note:  This is a KNOWN mutation.  Elders of the clan can recognize it by the difference in the bones.  This means that you do not need to go through some kind of miracle to discover the existence of the differences as you will most likely be told when your Shikotsumyaku is used near an older, wiser member of the clan.

If a user starts at Jounin, they may have the option of choosing Tansososa at start. That would alleviate the Exp cost but not the training requirement.

Description: This is the growth and extension of bone.  By using one's chakra to manipulate the Calcium deposits in their body and stimulating the growth of bone, one can grow bone anywhere on or within their body.  It can extend through the skin in the form of weapons, tools, or protection.  The user of this can have a maximum of 10 of these growths at one time, and must retract them to grow more, and the combination of the volume of them all must not exceed 2 cubic meters.

Description: This technique uses the off-shoot of the Shikotsumyaku to increase or decrease the amount of total blood within the user's bloodstream. The jutsu can also alter the amount of blood that is outside the body, but it requires B-Rank amount of chakra.  Excessive increase or decrease within the body can result in health problems such as high and low blood pressure.  These effects will last for 24-48 hours depending on severity.

Description: This technique is used to control and manipulate one's blood on a large scale, thus without such precise control and fragility that would be seen were one to manipulate blood within one's body.   The use of this technique can not only freely manipulate the shape and movement of user's blood outside their body, they can also control the density and sharpness.  The maximum strength and density of the blood cannot exceed that of iron, and the sharpness cannot exceed that of a general Katana, having a great deal of trouble slicing through a rubber tire.  This can also be used to manipulate the temperature of his blood (for clarity, it does not heat all of the user’s blood if s/he does not wish so), however not above the boiling point (100 degrees Celsius) or below the freezing point (0 degrees Celsius).  The speed that the user’s blood moves is normally,  one stat above the user's speed.  However, a BLM of A can increase it to 2 stats above. Once someone’s Speed reaches rank A, it only increases by one stat.

In terms of defense, sense blood is more or less a water solution, at its densest level, it has the same qualities as ice, except for the following:  Being liquid, damage can be simply filled in if any is applied, and it can rise to the density and strength of iron.  At its least dense level, it has nearly no defense, simply being a fine mist.

One can manipulate the route and position of blood within their body as well, lessening the amount of blood they are manipulating, thus allowing for more intricacy in its control.

Description: Think of this as a heightened version of the Shikotsumyaku: Extend.  The user grows copies of giving parts of their hand (nothing above the wrist) and simultaneously propels them at a maximum of 50 MPH in speed with chakra.  It has similar effects as ninja tools around the same size, so just the finger shrapnel like Kimimaro uses would be about the damage of a Senbon, while the entire finger would give the damage of a Kunai.  If the user applies chakra to the projectiles, they maintain momentum much better, sinking much deeper into the body.

Description: Much different than it's counter-part, Shikotsumyaku: Extend, this technique allows for the actual removal of bone.  Not to erase it, mind you, but take bones out of the body.  One could take the bones in their arm out of their body as a weapon, or other limbs and extremities.  (Note: This is SPECIFICALLY limited to limbs and extremities.  Arms and legs only.)  For the rest of the post AND for two posts after this technique is used, the area from which the bone was removed becomes unusable until the bone there grows back.  The bone is not removed exactly as is; it can be altered into blades and such and to achieve more balance.
