Ninja All-Stars: Clan Tora (2016)

Description from the publisher:

The Tora are, much like their totem the Tiger, a proud and haughty people, always ready to pounce, taking the initiative or advantage. The Tora find it hard to understand or trust anyone who won’t fight for their ideas or express their emotions with passion. Honor is of extraordinary importance to the Tora, and they pursue it and defend it with the utmost of their fiery passion.

The Tora have applied their fiercely competitive nature to the arena of the mind in the same way that they compete physically. Combined with their mountainous homeland, this inquisitive competitiveness has shaped the Tora into the preeminent smiths and alchemists in all Kagejima. Tora weapons are finely forged and their understanding of alchemical reactions is unsurpassed, leading them to make, not only the first firearms on the island, but the finest as well.
