While that would be a plot device, it wouldn't be a DEM, because it isn't resolving a conflict, but instead causing one.
It's also not an out-of-character thing for Happosai to do.
As a general rule for myself, I try to avoid setting an ironclad standard for what is and isn't DeM. It changes from situation to situation, setting to setting, and may or may not be plausible given the context.
Example: In the verse in question, there are certain people who can manifest their spirits into objects, most of which have supernatural powers and abilities. The hero in question has always loved to wander and find new things since he was an infant, and one day as a teenager, finds himself trying to deliver a message from a neighboring city that warns that a military group from an enemy nation is approaching. He gets turned around in the woods as night starts to fall, and is utterly lost. Fearing for his family and loved ones, his spirit manifests in the form of a magical compass to guide him to his goal.
This is not a Deus ex Machina. It is perfectly plausible in the context of the verse, as it explains both the sudden appearance of the device and why said device can solve the problem at hand.
Modified Example: Pondering the skating challenge issued for Akanes hand, Ranma steps outside to get some fresh air. Not looking where he's going, he gets lost in the city, and it's almost time for the showdown. Then, someone shows up and points him in the direction of the rink.
Now, this has the hallmarks of a Deus ex Machina, but this ultimately depends on four things:
1.) Who gave Ranma directions?
2.) Why did they give Ranma directions?
3.) Is it believable to you as a reader? Did you go accept the event, or did it raise an eyebrow?
4.) Is Ranma getting directions from this person going to be important later on? That is to say, is it setting up something to happen later?
If it's just a random bystander, I'd say it's a DeM.
If it's someone from the series who could have believably been wandering the streets at the time, knew about the contest, and would be willing to help him, it isn't DeM, but it's pushing it. Also, it's both DeM and OoC if Ryoga is the one that gives him directions (I doubt I have to explain why).
Did Ranma approach them, or the other way around? Does the event fit with the characters personalities? Is Ranma likely to ask this person (take into account his level of desperation)? Is said person likely to help him? If it's a no to any of these, it's OoC, and by extension, DeM.
Then we have No. 4. Let's say Happosai has been tailing Ranma for some time now, assessing his capacity and ability as a fighter and as a person. Ranma gets lost, and seeing an opportunity to garner influence, appears and offers Ramna directions. This is plausible in an AU situation, and it fits Happosais disposition. He can be surprisingly conniving when he wants to be, and wouldn't pass up the chance to get a potential favor later on. He does this, and Ranma is in his debt, which is something he could take advantage of later on. I would rule that an AU fic that has Happosai appearing 'out of nowhere' (to Ranma, but not completely to the reader) and offering help is plausible and in-character for him.
Also, it's important to note that there's an inherent difference between a Deus ex Machina and a Plot Device. A Plot Device is a device designed to move the story forwards. The One Ring and the Spirit Compass I used in my example are Plot Devices, as is Kage Bushen no jutsu, S2 organs, Excalibur, and any number of other aspects from various stories and series. Most of them aren't Deus ex Machina, but they are Plot Devices.
Plot Devices aren't a bad thing. Indeed, they're necessary to tell an acceptable story, to the extent that I don't think it's even possible to write a story without at least one Plot Device. It's an essential component of a stories structure.
A Deus ex Machina is, simply put, something that breaks your suspension of disbelief. We could get all technical and philosophical about it, but that's essentially what it is. If something doesn't fit, doesn't make sense, or seems strange or out-of-context, even if you can't quite put a finger on what it is about it that irks you, it's probably either a DeM, or some other structural error in the story.
And finally, I'd like to underline just how important the context is. Something acceptable in one verse could be totally unacceptable in another verse or setting. Ultimately, the best tool to tell whether something is DeM or not is your own reaction to it. It's your eyebrow that's being raised, and that should be your yardstick.
I also firmly believe that this is the source of nine out of every ten debates concerning what is or isn't 'right' or 'canon' in a verse. An excellent example is the Rasengan vs Chidori debate, which has happened both here and elsewhere. You can build arguments for both sides, but in the end, it's the readers expectations that rule what they themselves believe.
Naruto is the hero and main character of Naruto. The series is named after him. His place in it should be obvious. Knowing that, most would side with the Rasengan. Not because its mechanics are superior, because it uses less chakra, or anything like that. Fans of the series would mostly side with the Rasengan because it's Narutos Super-Special Technique that was created by his father and taught to him by his fatherÆs sensei. The Rasengan has a
legacy. When someone uses the Rasengan,
everyone recognizes it for what it is. From the perspective of the reader, the Rasengan is superior to the Chidori simply because itÆs Narutos jutsu, and heÆs the main character. Of
course itÆs stronger! ItÆs his special thing! The father he never got to meet invented it, and he was taught it by his fatherÆs teacher, who was himself a legendary ninja. The Rasengan is steeped in prestige. ItÆs a legacy of both the Village Hidden in the Leaves, and of Naruto himself. Compared to the Chidori, which was invented by a shinobi inferior to all three known Rasengan users, requires a Kekkei Genkai to work to its fullest effect, and is associated in every conceivable way with the concept of innate genius and skill, which is (or was) a recurring antagonistic theme in the series? ItÆs no contest, both from a reading perspective and the readerÆs expectations.
Now, is the Chidori superior to the Rasengan as a jutsu? Possibly. In mechanics, IÆd even go so far as to say ælikelyÆ. But just like a plot problem you canÆt quite put your finger on, you simply
know that the Rasengan æshouldÆ be the better jutsu, if not by itself, then in the hands of Naruto as the Main Character and Hero.
In the same way, there are some Deus ex Machina that simply defy classification. ItÆs not quite OoC, itÆs not outright uncanonical, and thereÆs nothing you can identify about it that makes it æwrongÆ. But despite that, thereÆs still something that bothers you about it, and that is something that defies logical classification or any rules we might try and make regarding it.
Like I said before, the simplest and most basic definition is when your suspension of disbelief is broken. Most notably when solving a supposedly unsolvable problem, but it can happen at other times as well. And suspension of disbelief varies from person to person. It depends on how analytical and logical they are, how likely they are to immerse themselves in the story as opposed to looking at it objectively, and how much their emotions get involved in the events taking place. What one might see as Deus ex Machina, another might see as nothing more than a Plot Device.
True, there are some things that are so blatantly Deus ex Machina that thereÆs an almost universal consensus about them. Yes, there is an æofficialÆ definition of what Deus ex Machina actually means, and you could apply that to get your answer in the strictest sense of the word. But your suspension of disbelief is a variable that is never quite the same between two people, which in turns causes discussion, debate, and ever out-and-out arguments over the story aspects that are more grey than they are black or white.
Trust me. If itÆs a Deus ex Machina, youÆll probably know as soon as you see it. Everything else (to me, anyway) is nothing more than semantics, nothing more than a never-ending source of fuel to feed the fires of debate. There are certain things people will
never stop arguing about, because they ultimately boil down to difference of opinion, either because canon gives nothing one way or the other, or because canon contradicts itself in a way that is never outright resolved by the author. While they can be entertaining to discuss, thereÆs ultimately no point in doing so other than to pass the time, as a consensus will almost certainly not be reached. Not even close.
For everything else? Just use you head. Like that link you provided. While Fallacies has a point, one that I readily admit is mostly correct, you ultimately have to remember the setting in question. Ranma ¢ is a Shonen, a comic aimed at preteen adolescents, mostly boys, which is a group not known for their flawless grasp of reality and physics. ItÆs a place where martial artists level mountains in a single blow, where gods walk the earth, slipping on banana peels in the process, and where a normal teenage human manages to summon the strength necessary to jam a boulder weighing several tons down the throat of a legendary dragon monster. Saving the First Lady from terrorists? ThatÆs par for the course as far as Ranma is concerned. Would it be pushing it in another setting? Given an even standard for what is and isnÆt expected, yes, it probably would. Is it here? No, not at all. If you can swallow Ranma making the Yamata no Orochi swallow a small hill with his bare hands in his female form
underwater with no visible effort or strain, then being in the right place at the right time for stopping a terrorist attack is nothing. A trifle at best. Something he does, goes out to lunch, then does again before dinner. A day-to-day occurrence. ItÆs one of the reasons IÆd never want to live in Nirn. Crazy nonsense is going down at all hours of the day. Even on holidays. Leave it to some psychotic klutz of a villain to try and steal Christmas and New Years to keep time from passing, thereby making him immortal. And itÆs not like Ranma can wait until
after Labor Day to save humanity.
Nooo, he has to do it
now. Yes, that means
now. No you
canÆt finish setting off the fireworks first. You can blow him up instead, though. ThatÆs good enough, isnÆt it? I thought so.
Fantastic things happen in Nirn, because Nirn itself is a fantastic place. For me, thatÆs really all there is to it. My suspension of disbelief for events in the Ranmaverse is nearly unlimited, provided said events are handled in a reasonable and somewhat plausible manner.
And sorry about the essay. I didnÆt mean for it to get quite that long. My bad.
