"For being able to use the orthodox method I know to treat your soul, besides the Death Law and the Life Law, Yale must also surpass the Law Master level in the Time Law, only in that way the Time Law would be able to affect the soul correctly and permanently. I almost managed to do it in my lifetime, but sadly my soul was injured when I was just about to reach that level, and it is impossible to improve in the Laws with the damaged soul. If I were able to remain just one year in this my current state, it would be enough to reach it myself and heal you, but I don't have enough time because I am already dead, using my power even for a bit of time like now, is already against all the laws in the world."
To completely heal a soul with orthodox methods, reaching such level was a must, people who surpassed the Law Master level in those three Laws were extremely scarce even in other worlds. After all, those Laws were all among the most difficult ones.
