If Awa is now a miniature Cauldron, a lot of people will take interest in you. Like.... A LOT...
Off the top of my head, NOL and Sector Seven will want to capture you, either to abuse the miniature Cauldron inside you or to stop you from wandering around considering that you could be constantly be leaking Seithr into your surroundings. Then we have people with ulterior motives. Arakune is going to try to est you on first sight due to you being directly connected to the Boundary. Litchi will want to know how you can retain a stable form despite being corrupted by the Boundary to almost the same extent as Arakune. Relius (aka. Perverted Masked Freak) will want to do god knows what to you. Etc, etc. You get the idea.
As for people who could potentially kill you, Cauldrons can either be destroyed through the
Power of Order, though not killed. Cauldrons can only be killed with the power of the Azure. You also shouldn't forget that Bang's Nail, the Nox Nyctores Phoenix: Rettenjo, is also the core of Kushinada's Lynchpin. So getting hit by that would probably have a similar if not stronger effect than Nirvana's Nails.
People with the Power of Order are Jin Kisaragi, Makoto Nanaya and Tsubaki Yayoi. The only person who can channel the power of the Azure at this point in time would be Hazama Honoka.
By the way,
@Mr.Ownage, what happened all the other playable characters that aren't selectable as mentors? You know: Bullet, the other Murakumo Units, Noel, Makoto...
