Chimei Tekina Mure

The Letal Pack (致命的な群れ, Chimei-tekina mure) is an organisation consisting of only the greatest blade-wielding shinobi of the Garō Clan. The swords of the twelve swordsmen are passed down from generation to generation since Mangetsugakure was founded, and are considered mystical and a treasure to the clan and village.

The swords seem to have their own soul and drain the chakra of anyone they have not accepted as their wielder. Each sword has its own desires and synchrony is required to be able to establish a link with its bearer, that is why the personalities of the wielders of the same sword are usually similar.

History
The swords were designed by a mysterious warrior for the clan. Little is known about the blacksmith but it is clear that it needs to meet certain conditions to be able to wield one of the twelve swords. Not only the swords are really heavy but their unusual shape makes it difficult to use them properly only by instinct.

During the Warring States Period the twelve swordsmen were capable of bringing order and peace to the place where the village was later built. Nowadays they are regarded as being the strongest shinobi in the clan and village behind the Alpha.
