True Fission-Fusion

Desko's modification to Orochimaru's cursed seal. It doesn't have much effects, and in fact doesn't do most of the things that Orochimaru's cursed seal does, not even absorb Nature Chakra. It is, however, the aspect of the seal that allowed Orochimaru's consciousness to be stored and revived at a later time.

Carving this seal into her own body, Desko proceeds to do a variation of the Fission Technique, pulling her fission out of the seal. A fission done this way will effectively be no different from Desko herself, and won't even have deterioration of skills, other than how Desko chooses to split her maximum chakra pool with her and her fission, and this cannot be changed unless with physical contact. For example, her fission could have 1% of her maximum reserves and she can keep 99% for herself.

In reality, however, there really is no difference between the two, other than perhaps the amount of time either have existed. Fusion occurs if her fission dies, and Desko gains any experiences (just like Shadow Clones), any growth in maximum chakra reserves and regains whatever chakra her fission had left when it died. If the originator Desko dies, Desko can assign a fission to become the next originator and the Fusion also happens.

Of course, Desko can perform this several times without rejoining, and any fission she creates can do the same as well. Desko and her fissions all share a link with each other, which is basically the same link that connects Shadow Clones and their creator. She can use and manipulate this link the same way she does with the link in Shadow Clones.

While Desko likes to fuse back with her fissions by physically joining back, it is entirely possible for them to fuse back through the link that connects them. Fissions can even fuse with each other instead of the originator Desko, if they need or want.

The seal is only used to stabilize the Fission part of the technique. Without it, a normal Fission Technique will happen instead, and Fusion will also occur normally.
