Trained from their very first year to the end of their days in this life, ninjas are a different kind of fighters, who don't rush towards their enemies, at least not where they can see. Better at hiding themselves than a chameleon and quicker than any other animal when they want to take the life of a target, a ninja is not what someone would want as an enemy. With bare hands they can attack and kill when it's needed, but the famous shurikens and kunais are weapons they can throw from anywhere without making more sound than a simple breeze does. When they are close enough, swords like their sharp and thin katanas or perfectly designed knives are all they need, creating a huge pool of blood with a simple strike, to make sure the enemy won't have a chance of standing again or running to call for help. They are divided in clans, therefore disputes happen and epic battles are expected when one starts to fight with the other, which can always provide a good action for the player looking for fighting games and some adrenaline. Excellent runners and a great source of knowledge of martial arts, it's impossible to not few like a true strategist or adventurer when controlling these warriors from the eastern culture. Their dojos in Japan are hidden inside forests and secret caves, unlike the kung fu fighters of China, but they will show the way to you if you prove yourself worthy of it.
