Just to let everyone (if anyone at all) who reads this world know~~~
Kyan was hit by lightning when she was 9. It reversed her hair color. She died. Kanda replaced her heart with Innocence and it brought her back. But she's still dead; ie no pulse no blood etc. She also has multicolored eyes from leeched innocence. Kyan is dead and therefore cannot die persay, but, removing the Innocence will cause her to revert to her true "form", ie dead. If you leave the Innocence out for too long she begins to decay and it won't go back in and she'll stay dead.

Just important to know before we begin!!!
