Even in the possession of Sugar who is technically a child she is still op with her fruit and with her fruit she was crucial for Doffy's hold over Dressrosa but it goes anywhere but there,nothing ever goes well for doffy so it seems but on the bright this particular devil fruit technically makes you immortal son which is just a cruel joke made by destiny.

But this fruit is really dark and twisted to be honest to be made a slave and forgotten by your loved ones and there is nothing to break her spell but fear seems to work but that would not be easy to accomplished either.

TLDR but looked at the picture I agree but law said he can’t use his room on users with strong haki so it might not work on ppl with strong wills

Speaking about Haki, Do you think this fruit's hability can be blocked by using Haki?

@Shadowind30 allows you to defend against hax devil fruit abilitiesif your armament is strong enough. ... Good haki can counter the attack power of Devil Fruits.

Yes i thing haki could be used against this fruit similar to op op no mi which can't really do much against individuals who have a lot of haku
