These prisons are basically Impel Down from One Piece, but more extreme and make less sense lmao.
Firstly, The Land and Air prison wouldn't work on the basis of the critical flaw of its structure. The Honey Prison is supported by a very thin beam, which is much smaller in size then everything else of the prison, one moderately strong fight can cut it and the whole prison goes down. We even see that in chapter 128 that beasts can climb up above the prison and destroy it how they please. The same goes for the Air Prison, all it takes is to cut the strings or just simply pop the huge balloon to cause the prison to be destroyed, and its not hard to do so unless the writer what's up a "Super duper dense and strong string" to hand wave it. Then there's the Sea Prison, and while there's no structural flaws with that one, there's still the problem on how they build it, did they use GT Robos?
On the Honey Prison, Love is the warden, which keeps all the beasts inside it calm. Since this prison probably existed for years, she probably wasn't around. Which means that without her, the execution beasts could not be used.
Secondly, How in the hell did they even manage to build these prisons safely if they were in these hellish environments? There's beasts everywhere that would kill humans if they try to build in that area. Did they receive help from the IGO president or something? The one that seems the easiest to create is the Air prison, but there's still a problem, Why did they decide to have the prison be carried by a balloon instead of engines that keep it afloat? As soon as they put the prison up, it might get popped by the aerial life forms, and we know how fragile balloons are.
Thirdly, from what we've seen from the Honey Prisons, the levels make LESS sense than that of Impel Down. The first two levels make sense. But then immediately falls apart there. The Fish and Meat levels basically mean the prisoners are slowly killed. The Main is simply killing them. And the last 3 are somehow worse than the main course. Getting cut and boiled really isn't an issue whatsoever for someone with gourmet cells.
Fourthly, In a world that's run of Food, The reasoning for people to be sent to these prisons is shocking. One of the reasons is that if you don't follow the worlds religion of worshipping food, then your ass Is gonna land straight to these prisons. Another is using a type of Knife that revitalizes an ingredient, allowing it to be used infinitely. While it make sense to regulate the use of these knifes to prevent economic imbalance, this knife would be useful to solve poverty and its hunger problems, Ala what happened to the world after the Cooking Festival Arc.
Fifthly, coming from the above paragraph, some of these crimes are too tame to be placed in these prisons or much more heinous to be placed in a lower level. Norisuke was placed in the Appetizer level for dine and dashing 2 trillion yen's worth of food, which if you convert that to USDs, that is 2 billion worth's of food. Now I can see why that can be serious, that isn't enough to be sent to the harshest prison of all time. What if he simply didn't want to pay for the outrageous prices? Which make sense, food should not be that expensive. How does that make him an A-Class criminal? Where are the B-Z classes? Criminals are targeted for their "lust for food", but isn't that what the normal people do since there's food literally everywhere for them to eat? Hypocrisy at its finest.
Anyway, there are criminals that deserve harsher punishments. "Joymar" Needs to be put at least 2 levels down, as he hunted 1600 individual animals of 17 protected species for their endangerment.
Lastly, there are the seasons that are extreme even for the human world. But how do these seasons started happening in the first place? How is the structure of the prison not break lose from all the environmental damage?
Overall, These Prisons were created by the author in an attempt to upstage One Piece's Impel down, when really he failed due to the sheer ridiculousness these prisons are for existing. There's a difference between "Prison" and "Murder Grounds", and The Honey Prison falls into the latter camp more than a prison. Prison is made to punish criminals, which the first two levels do, but the rest either kill them slowly, outright kill them, or are ineffective in punishment.
I like Toriko, but there's a reason why Its not a 4/5 and instead a 3/5. It has many flaws that become apparent if you look into it.
