Twin Snake Sword Großer Fluss

The Twin Snake Sword Großer Fluss (双蛇剣グローサー・フルス, Sou Hebi Ken Gurōsā Furusu) is a weapon that Nash Latkje wields in Genso Suikogaiden Volume 1 and Genso Suikogaiden Volume 2. As the name suggests, it is actually two weapons, used simultaneously.

Information
The weapon is made of two swords, Schwartz and Weiß. The two swords are connected by a wire and each blade can be divided further, connected by wire, allowing it to function akin to a whip when not being used as a sword. This versatility means that a lot of training and skill is required to be able to use the weapon effectively.

The sword is able to pass on a poison, called Zodiac Tower, which is fatal with no antidote even with the slightest scratch. The weapon itself is said to have almost a will of its own.
