The is a technique that expands on the fundamental attributes of the Shikotsumyaku by adding Chakra Flow into the mixture. While the Shikotsumyaku already provides the ability to mildly cause a change in the malleability of the bones produced through their hardening, the addition of Chakra Flow enables even greater versatility. This is due to the chakra allowing for the bonds between the structures to extend or even contract — in terms of distance — appropriately weakening or strengthening the constructs in question, while allowing them to be used for various purposes. Senhime's most prominent use of this technique is the creation of bone wires and bone whips, both of which are common mid-ranged weapons Senhime makes use of.
