'''Warning! Wall of Texts Ahead!'''

They never explained in details what the Seals are, and probably never will. We just have to settle with what we know:


 * 1) Seals belonged to each of the 6 demons and they have one purpose only, that is to close the Gates of Shadows.
 * 2) You can't use Seals to open the Gates, they're only for sealing, as their name implies. After the Seals are used to close the Gates, the Seals never goes elsewhere, they stay in the Gates. Each seals are connected to each demons in a much more personal level than just simply owned, so if you want to re-open the Gates, you have to defeat 6 demons again to break the power of the Seals, like what's demonstrated in Interlude.
 * 3) If you pays attention to the opening sequence, you'll see that Shadow put some kind of stone artifact to open the Gates. You might be wondering why Shadow didn't do the same thing after May got sucked. My guess is because previously, the Gates were closed by the combined efforts of the warriors of old times. Whatever these old warriors did, might be not really strong to seal the Gates forever. Alas, Shadow could opened them with just a simple artifact. Compare that to the 6 seals, which in my headcanon are stronger than the old method. Hence why Shadow can't do it with the stone artifact the second time; these seals are so powerful that the only way to break them is to defeat their owner.

And now about the demons. These demons were originally humans. They were either the strongest or the most evil warriors of this human world. Titan, who lacked an army to invade the human world, sucked them to the Gates of Shadows, and by whatever means turned them into demons. Basically, they will act as Titan's minions who will help him conquering the human world, as a replacement for his lack of army. They have been given the power by Titan to accomplish such thing (like Hermit's magic, Widow's charm, etc). Them demons, however, don't like this treatment. That's why they find Shadow's idea of re-opening the Gates disturbing, they hate being treated like puppets and don't want Titan to come there, to the human world.

Now if you ask, "then why did they refused to close the Gates in the beginning, if they were hating on the idea of Titan coming there so much? Isn't closing the Gates will prevent Titan from reaching the human world?"

...that's never explained thoroughly. But, I have 2 theories for this.
 * 1) They know exactly what would have happened afterwards if Shadow is to close the Gates; May gets sucked, Shadow comes to Titan, and Titan gains Shadow's ability to walk between worlds? Profit for Titan! So, they tried their best to stop Shadow, so he could never close the Gates and Titan's plan will never comes into fruition.
 * 2) These demons probably don't know the details of Titan's plan, they might not know better. The reason they tried so hard to stop Shadow from closing the Gates could be that they think that Titan could come out from the Gates anytime. Knowing Titan, they probably think that Titan will punish them with the ultimate judgement if they failed to do their tasks. Thus, they tried their best to conquer the human world and to stop Shadow. When the Gates finally closed, these demons are relieved that they will never see Titan again, only to hear Shadow wants to re-open the Gates.

As I told you, these two pointers are my theories, and they could be 100% wrong. What the demons are doing in the parts before Interlude contradict with the established idea of them hating Titan, after all :/
