The Kaguya Clan is known for their savage battle tactics and archaic values, and descendants of Kaguya Ōtsutsuki, as selected few have inherited a derivative of her original ability to manipulate one's bone structures. The Kaguya clan were descendants of Kaguya Ōtsutsuki, and selective few, namely Kimimaro, possessed the kekkei genkai Shikotsumyaku from Kaguya's original bone-manipulating ability. This ability was so powerful that even the war-loving Kaguya clan feared it.
The clan was noted for being very savage and battle-hungry, having no tactics when entering battle that they initiated simply to show off their ferocity. Because of this, they are fearless (if not insane or delusional), recklessly entering the battlefield and refusing to retreat even when defeat is clear, simply for the thrill of slaughter.

As descendants of Kaguya Ōtsutsuki, a select few were able to inherit the Shikotsumyaku kekkei genkai, which allowed them to manipulate their skeletal structure to weaponise bones for battle. This ability was so powerful, regarded as the ultimate taijutsu ability, that the other members of the clan feared it.
Apparently, the members who possess the Shikotsumyaku abilities have a different body structure than others, as when Kimimaro was fatally ill, Kabuto Yakushi claimed there had been too little information on his body to give any medical treatment. As such, checks made to heal a member of the Kaguya clan are done with a -10 modifier.
This kekkei genkai allows the user to freely manipulate their bone structure and weaponize it. As such the Kaguya member is able to make any one-handed melee weapon. This does not automatically grant them proficiency with it, but each weapon is treated as having an enhancement bonus equal to 1/5 the character's total level (minimum +1). The user is also treated as having a natural armor bonus equal to 1/4 their Constitution modifer, which applies to touch attacks as well.
