Personal NAME: Saigo-ban [Final Judgement] RANK: A CHAKRA USAGE: High CLASSIFICATION: Fuinjutsu ELEMENT: N/A HANDSEALS: 20 REQUIREMENT: A completely willing participant. "Archaic Knowledge" SA DESCRIPTION:     This technique can not be used on someone who does not consent. A person must fully agree to the terms of the deal before the effects of the technique take effect. The user will use their own blood to draw the kanji for 'Heart' on the center of the targets chest. After the contract is made the seal will begin to glow a dull red as the user asks questions. Any deliberate fabrication will result in the users heart stopping. This doesn't cover things like a lie of omission, but do prevent one from telling a deliberate, willful lie.

As KME and Kurama have emotion sensing esq lie detection, Himishi see pasts and Yamanaka read minds. I struggle to see an easy way for the explanation as to why this seal can tell someone's lying. Without it kind of overstepping what a fuuinjutsu should be allowed. Though I might not understand how archaic knowledge fits into this

I'm gonna pull this from Notify for now until I can figure out if there's a way I could rework it or not.
