Kuragan

 Kurgan (black eye) (目的 ). Is a recessive Dojutsu, Kekkei Genkai from the  Satō  clan  that allows the user to see chakra and individual charka signatures. However it is only seen once every three or four generations, thus making it very rare.

The user is able to see all charka and individual charka signatures, this allows users to track charka over a long range and can sense how much of their charka a person is using. They however cannot see the chakra network.

The Kurgan also allows the user to remotely control their chakra. This is done by either using kunai infused with chakra or sending charka directly to someone by touching them. This infects the opponents chakra with their own allowing the user to control it. Hatsumi can then do what she wants with the opponents chakra, such as disrupting the opponents chakra, adsorbing it, or taking total control of it.

Disrupting the chakra is where Hatsumi is able to send infrequent pulses of chakra in the chakra system of an opponent. This stops the opponent from creating jutsu, or jutsu that fail on a regular basis. This is mostly used on genjutsu, and larger ninjutsu, that would be harder to deflect in normal circumstances.

Taking control of someone's chakra is mostly used by Hatsumi, when a quick fight in necessary. Hatsumi will either infect them using a kunai or touch them. She will then send large amounts of chakra to the opponent causing them to explode, due to the pressure on the chakra system.

Hatsumi is also able to adsorb the opponents charka and heal a team mate simultaneously, this was done when Hatsumi was healing Natuto while Kakashi was battling. Little did the opponent know that Hatsumi was using the opponents chakra instead of her own to heal Naruto. This results in quicker battles as very few are able to keep battling, as it easily exhausts them and Hatsumi can reserve her chakra for emergences. She can also directly transfer charka from an opponent or from herself to replenish a team mate's chakra, if they are in a dire state, such as dying or are ill.

Despite being able to adsorb chakra, Hatsumi refuses to do it to people that she is either close too, or believe they don't deserve to have their chakra taken. Hatsumi refers to this as, “stealing Chakra,” However she has taken chakra from Naruto, when he was growing the nine-tails cloak and being out of control. This however caused her to have some of the nine-tails chakra within her for a few days and had the attributes of the nine-tails, for several hours. Such as the whiskers and the red eyes.

There are however drawbacks of frequent use of the <span style="font-family:'TimesNewRoman',serif;font-size:medium;font-weight:normal;line-height:26.0787px;">Kurgan , such as headaches from use of a long period of time. Hatsumi is only able to use <span style="font-family:'TimesNewRoman',serif;font-size:medium;font-weight:normal;line-height:26.0787px;">Kurgan  for up to three hours a day, during the fourth shinobi war this was increased to five hours a day. She also suffers from bleeding from the eyes, blurry vision, pain in the head and in severe cases blindness up to week.

<p style="border-style:none;border-width:initial;padding:0cm;font-weight:normal;line-height:0.69cm;orphans:1;">Hatsumi also has to maintain complete control of her chakra, as if she becomes angry or upset her chakra can latch it's self onto the nearest person insistently killing them. This happened to her during her chunin exams, where she killed her opponent during combat causing them to explode.

<p style="border-style:none;border-width:initial;padding:0cm;font-weight:normal;line-height:0.69cm;orphans:1;">Hatsumi also adsorbs people's charka without meaning to, such as during a skin to skin contact, such as a handshake or a kiss. It has been noted that her father had greater control over the side effects, and was able to stop himself adsorbing people's charka when touching them.
