I realize swords based on anime are reviled in most circles of sword collectors, mostly because they tend to be ugly wall hangers. That said I came across an image of a sword from a series called Tower of Druaga. The sword as you can see from the attachment is the typical big quasi buster sword type. What got me interested was the unusual fuller it had. I wondered if it would be possible to incorporate a fuller like that into a real functional sword or if the design was too impractical to work. I came across previously an alleged oakshott xiii-b sword design that I think would work with the fuller from the Druaga sword. It would also let it be a big sword that is functional. So could the fuller from the anime sword attached here be done or is it really too impractical? I don't care about the squiggles on it, just the fuller it has. Attachments:

well that XIII isnt that big, it looks like maybo 29in blade?
As for the fuller, I'm it could be made, but I doubt it would be beneficial to the functionality.

That fuller from the sword in Tower of Druaga is possible of course. But like Hiroshi mentioned, it is just for aesthetics.

it looks like it has two recesses in the blade,one fuller then another deeper one,unless the blade was really thick (too thick for practical purposes) then it runs the risk of ruining the structural integrity of the sword imo

As the others have said: of course it's possible, but whether or not it would be functional is another matter entirely. The only way I could imagine it being done and still being beneficial (i.e., lightens the sword without weakening it) would be if the main fuller that runs most of the blade length was very shallow and the the second near the tip was regular depth; basically, the full length fuller would be something like half the depth of a normal fuller while the second one was the depth found on production swords. Theoretically speaking, that'd be about the only way to do it while ending up with a structurally sound sword that's not Conan sword thickness and weight.

This. My first thoughts were that the sword would have to be tremendously thick for these fullers to have any depth. If we tried to bear some possible proportions on a mostly-normal sized sword, let's start with a one-inch-thick blade, and have each fuller be 1/4-inch deep to the surrounding steel.
The thickness of the primary fuller would be only half an inch, though, at that point. This would make the secondary fuller a hole. (yes, gradual taper and all, but ultimately the low point would be a hole; and speaking of taper, I imagine there'd not be much room for distal)
So should we go with 1.5"? Primary fuller's depth would leave 1" of steel, secondary would leave about a half-inch. That's a bit much.
So a 1.25" thick blade, fullered 1/4" twice? Leaves about 1/4" between the inner fullers. That's about the thickness of most swords, rough average. Pretty thick still.
Unless we take it another way and have each fuller, rather than a set depth, recess to a proportion of the surrounding thickness? Obviously half would be bad, as taking both sides down to the halfway point just leaves nothing. Let's go with 1/4. Again, with a one-inch thick sword (for ease) we'd have the initial fuller 1/4" deep, leaving 1/2" of metal between. The secondary fuller, though, would only be 1/4 of 1/2", or 1/8". this should leave about 1/4" between? Again, thickness of most swords there.
Makes me wonder if it might not be so impractical, sparing things like distal and/or profile taper by incorporating it into the fullers only...which sounds like a bad idea, but I wonder.
Either way, that's a heavy piece of metal. Too bloody thick in the cutting parts to do any good, really.
Then again, it might be doable?

Pretty much. It'd essentially be a ridiculously heavy metal club in the shape of a sword.
Lessee. Let's say the blade would be 6mm thick tapering to 2mm. That would mean the fuller would be about 1.5785mm to .79375mm deep. To do something like this with the same blade thickness and distal taper, the full length fuller would have to be .79375mm to .396875mm deep with the 1/3 length fuller at the top being about .396875mm to .1984375mm deep. Could it be done? Sure. But it'd be really freaking difficult and probably wouldn't offer anything significant other than being aesthetically pleasing.

Another way to do it would be to have the fullers themselves slope outwards as they move to the center section of the blade. This would be a more terraced effect, but it would achieve the idea of a double deep fuller without only the depth of a single fuller. Here is a crappy MS Word Clip art to demostrate the concept, which in retrospect I could have done much better had I just scanned something hand drawn. You can see how the middle fuller isn't very much narrower than the single one in the top sketch. Attachments:

Took me a while to understand that drawing! But I get it now...

Of course I would add that this is 100% aesthetic. I don't see any way it could possibly make the sword better, and in fact would most likely make it much worse.

This was about what I was expecting from this. However, regarding the top part of the fuller I assumed it was a flat section within the wider fuller as opposed to being another fuller within. I thought the whole thing overall was a wide shallow type with a flat section toward the top within the wide fuller with an engraved line acting as a thinner fuller toward the base. With that in mind would that allow it to function or is it purely aesthetic no matter what?

I wondered about the flattened section theory, as well, since there is no apparent change of depth in the small fuller, but I'd written that off as illusion by shading and/or the seemingly-inscribed text. I'd also briefly entertained the notion that it was, in fact, some magic spell of unknown effect.
I've not seen the anime or read any relevant media, and ultimately cannot pass judgement on the unknown...and, suffice to say, I am less than keen on learning more about this particular title. :?
All that said, maybe!?

Just a random idea, I know nothing about making swords:
Make a fairly shallow fuller run the entire length and have a one with normal depth near the end like Vincent said. But the blade would have no distal taper at all, just a little profile taper. The idea is that the deeper fuller near the end of the sword could *maybe* reduce the weight of the tip enough to make up for the lack of distal taper, and you could still have the fancy fullers.

I'm beginning to think that if I want this sword to be light enough for proper cutting I might need to make the larger fuller either etched or inscribed into the blade with a thin puller running through it toward the end. I'd give up the bigger fuller but the design would be more or less the same. That should allow a distal taper to keep the weight down right?
