Musubi

is a technique created and utilized by Orihei, and first used when she encountered Yama talking with Tenjin. After activating her dōjutsu, she focuses on the target, making use of the dōjutsu's sensitivity to space-time to diagnose the entry point used. Upon locating it, she makes a cutting motion with her eyes, the movement manifesting as a space-time slash that severs the link allowing the individual to persist in the material dimension.

Orihei noted the strength of the technique is contingent upon her emotional state. Targets that fill her with strong emotions, namely negative ones, appear to augment and amplify the technique, as Tenjin showed no traces of Yama's influence or presence long after the jutsu had been cast. Meanwhile, targets that had no discernible effect on her psyche (such as breaking the link between two random dimensions) would cause the jutsu's effect to be impermanent in nature, with the link between dimensions gradually reestablished.

Likewise, she can use this technique to bring dimensions or worlds together, using Musubi to create a "bridge" or "portal" that links like the two planes together. This requires a reverse engineering process of finding the point where the two worlds can be linked with minimal disturbances to the general multi-verse. When compared to its counterpart, this aspect is far more time-consuming and chakra consuming as it requires the user to look across vast expanses for this particular connection point. As with the severing ability, the strength of the "bridge" once made is reliant on the emotions influencing its usage to ensure its integrity.
