#dimensional prison

When it came to I-No, Illyrian Police practically threw in the towel, as they had no means of actually detaining her unless she actually "gave up" willingly.

And actually, the same is mostly true of Ariels as well, though they lucked out when Sol took her down.

Asuka's case was also unique, as he knew people were going to come after the Tome of Origin, which he possessed.

Even in Sol's case, Goldlewis (Secretary of American Defense) knew that asking him for a public execution would be unreasonable.

But here's the counter-argument:

Sol Badguy challenged I-No, even without his powers. He had the guts to do what no other American Soldier (or Illyrian Knight) dared broach to try.

Granted, it was a gamble. A very big gamble at that.

This goes back to Sol's conversation with Ky on "how to confront someone".

How DO you confront a performance artist? How DO you confront an expert on Magic?

In the case of I-No, Sol had to appeal to her pride. He "showed" her how powerless he was at the outset, and yet he challenged her again. She was "forced" to defend that unnecessary pride of hers.

This wouldn't work on someone like Happy Chaos. Happy Chaos has contingencies upon contingencies. Even if you think what you're doing is working, he will instantly turn that thought against you.

So how do you confront someone who thinks ahead and "knows" about everything?

You show them something they "don't" know... or, at least, "think" they don't know.

Happy Chaos is someone who goes with the flow... he won't do anything to go against that flow.

Not, unless the flow itself is disrupted.

If something unexpected happens, if something he has no control over happens, or if something he has no knowledge of happens... of course he's going to be interested!

But that alone isn't what would catch him.

What would catch him is if you had a means of having him corner himself in his own logic.

In much the same manner as how Batman has (time and again) outsmarted the Riddler.

Even if Chaos has no rules, he follows his own rules, even if those rules can't normally be seen.

Put him in a situation where his own rules defeat him, and you just may have a chance in catching him.

Of course, that's all speculation... but it would probably be the best opportunity.

That said, most "Crusades" Criminals were sealed in Dimensional Prison, where even their own Magic couldn't influence the outside world.

In the case of Justice, it was a powerful slow-acting seal that sealed her away.

In terms of function, perhaps, but not in terms of cost.

Most OutRage Jinki require a base amount of Mana (Houriki) to be used and even controlled.

In terms of what the Thundersealed Sword did, even Ky himself is not aware the reason it activated in response to his need in saving Dizzy.  If anyone would know the real powers that the Jinki have, it would be Sol, who built them.

Compare/contrast with the Ouroboros Loop "theory" that Sol spoke of, which undid the seal on Ky when he was sealed away by Valentine when she first attacked Illyria.

It's unclear exactly why she spared Ky, only that the end result caused him to be sealed away in a similar seal to that of Dizzy, though in her case, even if the seal was undone, it could not stop the sublimation that was affecting and eating away at her body.

To undo the sublimation would require Valentine to be defeated, or so it was suggested at the time, since the spells were tied directly with Valentine's powers.

Most dimensional-based theories (spells) and even barrier seals (like the one that sealed up Justice at the end of the Crusades) usually follow certain rules to be activated and triggered.

A very powerful seal would require a slow activation, or at the very least a great deal of mana to be used to make up for the amount of time it would usually take for the spell to activate.

Since Valentines are already blessed with a great deal of mana capacity, casting such spells in quick succession would be an easy feat for them compared to humans (this was also true of Justice, whom Valentines are based off of).

In Ky Kiske's particular case... because he did not have the base mana to establish the Time Seal spell to halt Dizzy's "time".... the Thunderseal itself was used up as part of the cost.

Again, why this happened, and what exactly triggered it, aren't fully known yet.

Moving on... in regards to how Axl Low's powers influence time... they have an even greater cost, greater risk, and there's less capability for them to be controlled.

The "cost" in Axl Low's case, relates to how this world's Timeline is asserted.

Throughout much of Axl Low's misadventures, any time he time slipped, it was somehow connected with his memories and emotional state.  He wasn't aware of it at first, but now he has some idea of how to control these powers at will.

Axl himself would never time slip in places where he could not exist or had not existed previously in terms of logical placement.  Even if he visited a place completely abandoned by humans or any other living creature... said place was still connected with past memories of places he had been before, or would later visit, or connected with people he once knew.

But as it happens, each time Axl Time Slipped... the Timeline he left previously would cease to exist, asserting a new timeline each time.  That itself was the cost... and it was a hefty cost at that.

While Axl can slow down and halt time temporarily, there's an exchange involved whenever he does this.  For example, if someone died in the previous timeline, so long as he asserted this current timeline, there would be no means to bring them back or alter their fate.

It's also not possible for Axl to visit previous timelines he has left behind, so even if he can "slow time", he cannot change or halt it forever, at least without consequences.

By slowing down time in "this timeline", he asserts his influence and power within this timeline itself, but because of the heftiness of his powers, he currently has no control over "how much" he can use or how much he can influence.

While Dimensional Seals (or Dimensional Prisons) can halt/isolate an individual's "space/influence", they cannot entirely halt a person's "time".  A good example of this is when Zato=ONE was having a conversation with Eddie while he was imprisoned by the Conclave after his revival.  Even Justice was able to temporarily influence Testament while she was inside her Dimensional seal.

Even in the case of Miyabi, the Japanese Dimensional Colony, while the barrier itself does affect space around it, and even has artificial weather and seasons within the barrier... all the Japanese residents inside aren't fully sealed, and continue their personal lives as they normally would, albeit in a quarantined state.

While the Thunderseal did, in fact, temporarily slow the progression of Dizzy's time, it still came at the cost of the sword itself.

It's still a mystery in fact that the Thunderseal was able to regenerate itself after the fact, since the cost of activating such a spell was very high.

We also do not know if the spell was later undone by itself, or if Dizzy simply broke the spell herself (VastEdge's story was vague in telling us the result).  The latter of which would normally not be possible without outside influence (even if Dr. Paradigm was or was not involved).

In general, most Isolated Spaces or Barriers (like the Cube for another example), are a kind of space magic that isn't normally established without some high cost to begin with.

In Testament's case, he not only needed the blood of several victims, but his very own blood to undo the seal placed on Justice, so even he paid a very high price as well.

I hope for an Exector sequel as well (with a little less Engrish)!

Back on topic:

Ariels tried to seal the Original Sage away inside her body but that only corrupted her and drove her further in to insanity (and she's technically NOT human by any normal standard, so going insane actually did a number on her).

Assuming there was a way to seal him away through Magic, chances are he already knows about it and knows the loopholes of the Backyard to get around it.

Actually, a few paradoxes have already tried to do him in but he took advantage of them (one of them was an Alternate Closed Timeline version of Nagoriyuki).

Technically speaking though, he WAS imprisoned for nearly over 100 years already... and is as old, if not older than Asuka and Frederick (Assuming Frederick was in his 30s as of 2016, he and Asuka both would be over 200 years old).

Assuming that being imprisoned wouldn't be a reasonable way to rehabilitate him, it would probably make more sense for him to end up doing Community Service under heavy supervision, but since he's capable of creating copies of himself, decoys no less... uncovering his hidden actions would be harder to do than just simply keeping an eye on him!

At the very worst, they'd have to develop an artifact that could seal his Magic Ki pathways to prevent him from casting anything, presuming one could even put such a collar on him successfully (or even with his cooperation). Similarly, most likely, to the Slave Bomb Collar that Potemkin used to wear, but more high tech and restrictive.

That all being said... Gears "technically die" when you destroy their central core: the bundle of Gear Cells that is the core of their ability to regenerate and obtain Magic Energy. The conduit for that Magic would still be there, even if they were a dormant corpse, but at the very least it's one way to destroy an immortal.

Still, Nagoriyuki can "see" the vulnerability in Happy Chaos' hand, so exploiting that weak point could destroy his body, but the full effects on him aren't fully known, if any exist.

Furthermore, they could treat him like how some Vampires are treated: carving his body in to sealed relics and spreading each piece to the far reaches of the globe, if not jettisoned out to space.

Gruesome and Inhumane as that prospect is, if it got rid of him, that would ease peoples' concerns.
