THE PUPPET TECHNIQUE

The Puppet Technique is a unique ninjutsu fighting style; this technique uses chakra threads to control puppets like marionettes. Any number of chakra threads can be used to control a puppet, but users with more skill can use fewer strings per puppet. Both Chiyo and Sasori demonstrated the ability to control entire puppets perfectly using just one thread. While most puppeteers (kugutsutsukai) would normally be able to control ten puppets at most (one per finger), Sasori's self-modification allowed him to control up to one hundred puppets at a time.
This technique has few weaknesses: according to Shino Aburame's observations during his fight against Kankurō, the Puppet Technique is a long range style, meaning that the puppeteers are weak against close range fighters. Since most puppeteer use his or her hands to manipulate the puppets, if their hands are disabled, then the technique can be neutralised. And because the puppet's movements are based on the mechanisms that were installed inside, interfering with said mechanisms can stall the puppet entirely.
This was demonstrated by Shino during his fight against Kankurō, where he used his bugs to infiltrate Crow's joints, rendering the puppet immobile, and then again by Sasori, who used the Third Kazekage's Iron Sand to stall Chiyo's mechanical Chakra shields. Also, while controlling the puppet, the user is wide open if the opponent bypasses the puppet. For this reason, puppeteers avoid hand to hand battle, relying almost exclusively on their puppets instead.
Another weakness is that a puppet's movement is dependent on the will of the user, and as such there will be a time lag between the user's commands and the puppet's response.
Sasori has managed to create innovative methods that can bypass such weaknesses, such as Hiruko, which is worn like a disguise, serving as armour and defending himself from attacks, and converting himself into a puppet, he can fight at close range without worrying about leaving himself wide open for a counter attack.
In Naruto Shippūden 4: The Lost Tower, the main antagonist  Mukade could use this technique to control an entire nation full of puppets at very long range, which numbered in thousands; he achieved this by connecting his chakra strings to a large pillar and pipes specialised in flowing chakra throughout the entire Rōran, expanding the number of strings and distance he can utilise. The inventor of this technique is Monzaemon Chikamatsu. Originally used for entertainment purposes, he worked diligently with other shinobi to convert the theatrical art into a unique form of combat

After unravelling the carrying scroll, the Chikamatsu Collection appears from the gate (, mon) crest. Using the Puppet Technique to manipulate them at will in what is known as the "an amount matching ones fingers" ( Yubi ni sū) method. With this puppet collection it is literally possible to use one puppet with each finger — each boasting a power matching a thousand puppets put together. However, to use all of these secret mechanisms demands extremely high class expertise and skill.

These ten puppets were created by the first puppeteer Monzaemon Chikamatsu and later came into Chiyo's possession, the use of which earned her great fame. These puppets are very powerful, as Sasori claimed that there were rumours that they had been used to take down an entire castle at one point in time.The Chikamatsu Collection has terrifying prowess in taijutsu, ninjutsu, bukijutsu, and so on. Furthermore, as they can change their numbers by combining, the number of abilities they can show becomes even greater. The puppets were constructed in such a way that they all can work in tandem with each other both offensively and defensively.

To begin this technique, Sasori removes one summoning scroll from his back. He then opens his right chest compartment to emit more than a hundred chakra strings, which reach into the scroll. From the scroll, more than a hundred puppets wearing red cloaks emerge.
As even the most elite of puppeteers cannot control more than ten puppets a time (one per finger), this technique is proof of Sasori's superiority with regard to the Puppet Technique. Also, normally a puppet's movement is dependent on the will of the user, and as such there will be a time lag between the user's commands and the puppet's response. However, since these hundred puppets are directly connected to Sasori's core, there is no time lag between Sasori's will and the puppets' movements.
Sasori claimed that he had brought down an entire country with this technique. Many of the puppets however, were destroyed during Sasori's battle with Chiyo and Sakura Haruno, although they did manage to destroy some of Chiyo's White Secret Technique: The Chikamatsu Collection of Ten Puppets. While these one hundred puppets lacked teamwork, they apparently used sheer attrition and numbers to overwhelm their opponents. Even when they decrease in numbers they do not become less dangerous as it merely allows Sasori to focus more on the remaining puppets.
As with all of Sasori's puppets, all the weapons wielded are coated in his special poison, which would kill the victims after three days of painful paralysis.
