Is there any way to make this picture work as a rules legal character?

So I found this great picture and I'm absolutely stumped as to how to make it work.

If you can't see the picture, it's a rogue looking individual who is wielding a double-bladed sword in one hand with another sword in their offhand.

Is their anything that would let you dual wield a sword and double sword and be able to attack with all three blades? Besides GM fiat, of course.

There are no double light or one-handed weapons in Pathfinder, to my knowledge. Even if there were, the limit on off-hand attacks isn't determined by the number of weapons you have at your disposal. For instance, you couldn't make a greater than normal number of off-hand attacks by wielding a weapon in each hand along with armor spikes.

The question is then why you want a double-bladed sword in one hand. If it's just for visual effect, then I would just reskin an existing sword, or homebrew a new exotic weapon (though not a double-weapon).

Double Weapons: Dire flails, dwarven urgroshes, gnome hooked hammers, orc double axes, quarterstaves, and two-bladed swords are double weapons. A character can fight with both ends of a double weapon as if fighting with two weapons, but he incurs all the normal attack penalties associated with two-weapon combat, just as though the character were wielding a one-handed weapon and a light weapon.

The character can also choose to use a double weapon two-handed, attacking with only one end of it. A creature wielding a double weapon in one hand can't use it as a double weapon—only one end of the weapon can be used in any given round.

Maybe the person's holding a Small double-bladed sword. Yum, -2 on top of the normal two-weapon issues!

Aside from that, I think your choices are:
-Reskin. It's just a sword with a long sharp pointy pommel with no extra features.
-New weapon. Call it a double scimitar or double sabre or whatever. Single sword damage, you just have two ends to stab with and two ends to enchant. Benefit over carrying two actual swords is having both in your hand at any one time. And each attack uses only one end like normal double-weapon rules. Basically the Small double-bladed sword but without the -2 for size.

If you don't want to deal with weapon size shenanigans, a Titan Mauler Barbarian can use a two-handed weapon (such as a double weapon) one-handed.

The art is awesome.
It reminds me of a final fantasy 7 character who used an over-sized shuriken in one hand. You could fluff it as a Star-Knife in one hand?

So, given that the double weapon is treated as a one handed weapon, when wielding it one handed (and only one side of the weapon can be used when wielding it in this manner) I would recommend going Two Weapon Fighting Ninja. It gives you proficiency with the Wakizashi and the Naginata. While the Naginata is most often a polearm with a katana-like blade on the one end (not too different from a fauchard), there are double sided variants. So long as you are only attacking with the one end, and pairing it with the light Wakizashi, there shouldn't be any additional penalties beyond the standard TWF penalties.

Thanks to everyone for the feedback. Yeah, I'll probably have to reskin or homebrew something. I just wanted to make sure I hadn't missed some kind of obscure feat or class ability.

Make the materials that the double weapon is made from different for both ends (e.g. cold iron/mithril). It'll get expensive, but then it makes sense that your character has this double bladed weapon and switches which blade is used depending on what the situation requires.

[Knight Magenta]

You can flavor the sword as a weapon with Defending or Distracting qualities. Then make a Crane Style or Two-Weapon Feint using character.

[DM Livgin]

Use the bard juggler archetype to get your effective third hand.

Conceptually this rogue fights with the double-sword typically, but applies a powerful poison to the short sword to switch hit it in when needed for maximum effect. Or she is a demon hunter, and the short sword is cold-iron where the double-sword is regular enchanted metal. Or she is goodly agent of justice smiting humans that have committed great deeds of evil, the double sword is enchanted for run of the mill combat, but the short-sword is a +1 human-bane holy sword.
