Allow me. This is the Ultimate type of fail safe. What you are basically saying, is that by no means, can you be killed if someone attempts to take out your heart with some kind of attack. To be able to seal objects, humans, chakra, bijuu, demons all in one thing, is just a no. This will never fly on this site. So I see it best you take a different route. This is god mod x25,000 + 1. From what Im reading, there probably wont even be a way to get it adjusted. This is because you cant limit sealing bijuu to within a clan, and you cant have a single seal that seals everything. This is far beyond a GOD. This is every god known to all religions wrapped up into one, then multiplied tenfold.
