Jarul: "...No, that is not it. If one attempts to eat it, the guarding hammer “Ragnir” will interfere!!
In Elbaph, we have a legend regarding a warring deity, who is said to wield the weapon “Ragnir”.
They say he turned into a gigantic dragon and WENT AGAINST the “Sun God”...!!
And beside him was his trusted servant, Ratatoskr the “Ice Squirrel”.
When the warring deity died, Ratatoskr's spirit passed into his master's hammer.
And ever since, “Ragnir” has protected that Akuma no Mi until someone powerful enough could inherit it!!"
