There is something about the derous knife that is interesting to me. We know that derous's body has healing properties we can assume that also means his tooth, the one tooth that he used to rule the planet, i think somewhere in the manga it asserted that derous was once the strongest creature on the planet. We also know that derous guards the cure water. Cure water by what i've seen, the difficulty of getting it, close to one of the full courses, derous explicitly GUARDS the cure water, ACTIVELY. Like we have seen with air becoming such a vital part of heracles's life we can assume that cure water is one of the reasons why derous's body has healing properties.
This however is just setting the table this is not the theory i have, i'm just putting game out there, I'm sure most of you have already thought this out but then that brings me to the derous knife that komatsu has. It's not the first item that we have seen that is made from the body of one of the eight kings *see jirou's knocking gun. But it's the only knife made from one of the bodies of the eight kings.
One of the things that make the derous knife special aswell is that it was made with MELK STARDUST. Melk stardust is more or less an edible addictive substance.
Melk stardust was also used to make the derous knife. As far back as i can remember AIR the the first big ingredient komatsu cooked with the derous knife. With a combination of food luck and this "god cooking" he was able to prepare it, but he pushed the taste of air past it's natural threshold, to 120% the manga said I think. That...that's amazing, he made one of acacia's full course ingredients BETTER, than what it was supposed to be, don't know how fhroze made it but that's whatever.
I don't want to be long winded i'm tired of typing, j/s melk stardust may be augmenting komatsu's cooking ability
We saw komatsu simply poke pair and it was prepared..i mean...melk stardust man no other knife in the torikoverse has melk stardust in it.
Melk Stardust the Real MVP
