Sharingan: Transcription Seal

Sharingan is in the name of the technique, but it doesn't actually require a Sharingan to use, but rather, refers to the origin of this technique

Desko, after dissecting the Sharingan's ability to transcribe its own techniques into Sharingan eyes, sought to replicate this ability to be able to be used generically for most or even all techniques. She did eventually succeed, creating the Sharingan: Transcription Seal that allowed one to transcribe techniques into not just the Sharingan, but also other objects and other living beings with a specific seal, which activates when certain conditions are met, which could be at the user's or the receiver's will.

She then also managed to turn it into a Ninjutsu, allowing her to separately store Techniques that activate when certain conditions are met, which also could be at her will.
