"The ability to manipulate "laws" that automatically apply themselves upon reality, referring to rules, mandates and even fundamental logical principles/truths/facts that are the way in which a reality may function."
Ah yes, but of course, except that's not what's happening with the Dragon Quest, now is it?
Through immersion, when you enter the said story, you are not part of it at all. Literally. You can't be part of it. It's like a bug in the system, it shouldn't belong. The bug doesn't operate under the established rules of the system due to it being from outside aka shouldn't be there in the first place. Another example; a virus enters a human body, it doesn't operate under the established rules of this place - now manipulating those rules, if you could, won't grant you law manipulation either because at most it would be biology manipulation - so it causes mayhem. That's what's happening here. Arale shouldn't belong in the game, so when she entered it, the game became her playground, simply because the code is already written there and she is just manipulating the data to suit her needs. In the previous thread, we agreed that the reason that is happening is because of her data manipulation - which comes via toon force. Inside a digital space, there is only data - millions upon millions of lines of code. All she is doing is manipulating the data in ways to suit her. That's not resistance to law manipulation, because everything inside the game is data, pre-developed codes and she is manipulating that through toon force. Looking at it now, it should theoretically upgrade her data hax when immersing, but nothing law hax.
Now that I look at it, even resistance to data manipulation seems sus. The game is already created and shipped, and it doesn't come with a self-reassembling mechanism, no game does. If it did, it came with something as advanced as that, then data manip resistance can work, but it doesn't, so even data manip resistance - I think one came from here - should be removed.
In addition, when a higher infinity being comes down to lower infinity, they are often unaffected by the laws of physics, simply because they transcend that system of causality. That's exactly what is happening here. She is from a higher infinity, and the game is a lower infinity - we will use infinity for the lack of a better term - and of course, the lower infinity doesn't follow the same rules as the above, so that's why they are unaffected by these rules set in place. You could argue that they should get law manipulation resistance... but why would they? They are just simply operating in a different causality system. They would, however, get law manip resistance if some character tried to use their hax and it didn't work at all, sure. But simply because they transcend that system of laws doesn't grant law manip resistance at all.
Now, back to Arale. In the chapter, we see her enter the game and she takes more people than is allowed by the rules of the game. But she continues through that just fine. Now, why would this be law manipulation resistance when it is one of the clearest forms of data manipulation? She is manipulating data, codes to suit her need. And rules, in this game, are also data. Everything is data.
So, now to you... Can you explain to me why you think manipulating the data of a game is somehow resistance to law manipulation? And keep in mind, she is a bug in the system, and the system has no way to actually fight her or reinforce its laws on her because it's already pre-developed without that kind of problem in mind.
