Doujutsu are abilities associated with very unique bloodlines. Said abilities are very unique to the clan and lineage they come from. These abilities are typically specialized, complicated, and in most cases may not be duplicated or learned without their coveted blood running through the individual's body. Below is the list of various clans and bloodlines which will lead to descriptions of what each clan has at their disposal.

Uchiha Clan & the Sharingan

Description

The Uchiha clan were one of the founding noble families of Leaf village. The clan itself is said to be descended from the Hyuuga clan who possess the bloodline of the Byakugan eye. Because their clan possessed the Sharingan or "Wheel Eye," the Uchiha excelled at being able to read and fend off attackers. This made them prime candidates to help found the Konoha Military Police Corps. The organization itself would go on to incorporate the Uchiha fan symbol into their official logo. Select few members of the Uchiha clan possess the ability to activate the bloodline Sharingan eye. This doujutsu (eye skill) gives one the ability to read Genjutsu, Taijutsu and Ninjutsu and then defeat it. As such, the clan member can view a technique being performed and see the tricks and movements required to be able to complete it. However the clan member can not copy techniques which are unique to another bloodline. It also gives one the ability to cast jutsu techniques only possible by possessing the eye. The clan itself is known for their ties to fire. For a clan ninja to be seen as an adult, they must be able to utilize a Katon (Fire Element) jutsu such as Goukakyuu no Jutsu. Thus is the tie between the manipulation of fire and the mind of an Uchiha member. Below is a list of details regarding the clan. Eye variations are earned just like jutsu, are trained for an earned.

the Sharingan

Sharingan is the blood inheritance limit of the Uchiha Clan. The Uchiha are said to be descendants of the Hyuuga, with the Byakugan changing into the Sharingan over time. This doujutsu (eye skill) gives one the ability to read Genjutsu, Taijutsu and Ninjutsu and then defeat it. As such, the clan member can view a technique being performed and almost instantly memorize the movements required to be able to complete it, including the needed chakra moldings and seals used. However the clan member cannot copy techniques that are unique to another bloodline and the clan member must have a body capable of meeting the chakra and physical requirements to do the jutsu. This rarely stops the clan member though, as such stressful situations often push their limits farther and allow them to harness their full potential. The Uchiha clan member is not granted the Sharingan at birth; it is only activated later in life, typically during a time of emotional stress in the heat of battle. The Sharingan itself can be transferred to another non-Uchiha by a medical ninja, such as happened with Leaf ninja Uchiha Obito to his teammate Hatake Kakashi. Because his body was not born to carry the Sharingan, the eye is always activated and it burns Kakashi's chakra when used. To lessen the impact of the Sharingan on Kakashi's body, he normally keeps the eye hidden and out of use. Also of note, is the fact Kakashi, a non-Uchiha, was able to advance the Sharingan from two tomoe to three tomoe after gaining the eye. The Sharingan itself contains three tomoe (comma). A higher mastery of the Sharingan can be seen in the creation of a new tomoe in the eye, with three tomoe being the typical highest form of the eye. The rare Mangekyou form is a unique evolution of the Sharingan beyond the three tomoe form, please see its entry for more information. An eye possessing two tomoe can allow the Uchiha clan member to track the movement of an opponent and do some minor copying of an opponents attack. For avoiding incoming attacks, the Uchiha's speed and agility will greatly control whether they can move to avoid it. However, three tomoe will greatly help in this area. Two tomoe will also allow the ninja to pierce Genjutsu and see the surrounding reality for what it really is. It can also allow the member to pierce another’s body and see their chakra. While the eye is not refined enough to see the tenketsu and chakra circulatory system like the Byakugan, it can view the movement and flow of chakra. This can help them tell if a person is trapped in a Genjutsu, or if an attacker is a real threat or merely a bunshin. An eye containing three tomoe will allow the ninja to see the image of an attacker’s next move from the slightest muscle tension in their body. This prevents wasteful movement and allows the Uchiha clan member to conserve much needed chakra in battle. It allows them to synchronize their movement to strike at an area moments before their opponent is even in that spot, essentially allowing them to strike out and hit their opponent before they're even there. Three tomoe also grants the Uchiha the ability to do Genjutsu and hypnosis after locking eyes with an enemy. This can be used to cause their opponent to do an attack of the Uchiha's choosing. This hypnosis can also be used as a Genjutsu counter, which is the ability to turn a Genjutsu spell back upon the original caster without the requirement of forming any handseals. Note: For the sake of role-play on this forum, the predictive capabilities of the sharingan are treated mostly as a moot point. That is to say, having the sharingan won't give any character a drastic advantage in combat. At most it will justify a moderately more agile character but will not be very easily abuseable. People who abuse the predictive capabilities of the Sharingan will not be permitted to play an Uchiha. Copying jutsus has also slightly been modified for sake of character growth. First, you can not copy a technique your character could not naturally learn. This applies mostly to elemental releases. If you do not have the element released for the jutsu you are copying, you can not copy it. Second, copying jutsus is something done only for the fight in question. Because you copy the jutsu in the fight does not mean you've learned it. This is simply done to keep things interesting and to avoid people from bypassing the training and development process. This in mind, if you decide to learn a technique you've copied in the past, you will receive twice the SP you would normally earn from training it. Furthermore, Sharingan genjutsu will be elaborated in greater detail later in this description. Many people have enquired about obtaining the sharingan much in the shape and form Kakashi had. There are a few details regarding this matter about what is and isn't permitted. You are free to pursue an Uchiha, but it needs to be a full blown player character. Not an NPC, not some character your buddy makes up for the sake of you getting an eye. If we believe that there is something questionable about how you obtain your sharingan, we will block it. It should also be noted that you will not have access to all of the Sharingan's abilities. For example, you can't "shut off" the sharingan. This means while you stare through it, you are using the increased chakra expense associated with it. Additionally, you only gain access to the peaked senses and the most basic form of hypnotic jutsu. That would mean that you can copy jutsu and influence future jutsu an opponent casts with eye contact, but not create elaborate illusions.

Unactivated Sharingan

The normal eye for an Uchiha clan member resembles any normal human eye with iris, pupil and sclera. Obtaining: This is the default form that an Uchiha's eye takes.

Partially Activated Sharingan: One Tomoe

This is the first variation of a partially developed Sharingan eye. The clan members pupil will turn red and develop one of the wheel swirls. When Uchiha Sasuke finally activated his Sharingan, his left eye took this form. Perception of one's sorroundings is slightly enhanced. Though the one tomoe sharingan yields minimal to no benefit. Obtaining: Rank C jutsu training. For purposes of simplification, when this skill is trained for, both eyes are partially activated.

Partially Activated Sharingan: Two Tomoe

This is the second variation of a partially developed Sharingan eye. The clan members pupil will turn red and develop two of the wheel swirls. When Uchiha Sasuke finally activated his Sharingan, his right eye took this form. With two tomoe, the user can do minor jutsu copying, perceive subtle movements, pierce genjutsu, and view formations of chakra. Obtaining: Requires the One Tomoe sharingan. Rank B jutsu training. For purposes of simplification, when this skill is trained for, both eyes are partially activated to this level.

Fully Activated Sharingan: Three Tomoe

This is the final normal form of the Sharingan eye. The clan members pupil will turn red and develop three of the wheel swirls in both eyes. In this form the clan member can read Genjutsu, Taijutsu and Ninjutsu, learn how the skill is done and then copy it to be used later. This level of the Sharingan permits a great deal of agility, allowing them to better conserve and direct their attacks based on an impressive level of perception. Three tomoe sharingan allow seamless copying and interpretation of a wide array of jutsu. At this level, the sharingan can perform genjutsu and hypnosis if eye contact is made and the ninja has access to the appropriate genjutsu training (see jutsu below). Additionally, keep in mind that the Sharingan's ability to be used effectively is dependent on visibility and sight range. Obtaining: Requires the Two Tomoe sharingan. Rank A jutsu training. For purposes of simplification, when this skill is trained for, both eyes are partially activated to this level.

Mangekyou Sharingan

Sharingan is the blood inheritance limit of the Uchiha Clan. The Mangekyou Sharingan is a legendary doujutsu ability which has only emerged in a few clan members in its history. There is still mystery surrounding the eye and the Uchiha clan itself. Each user develops their own unique looking Mangekyou. The requirements for gaining the Mangekyou are very controversial in nature. After Uchiha Itachi murdered his best friend Shisui he gained Mangekyou. He told his younger brother Sasuke that to gain the Mangekyou, he too would have to kill his closest friend. Itachi told Sasuke that a scroll in their clan shrine revealed the true original purpose of the clan doujutsu. This scroll and Itachi himself revealed that the former leader of their clan, Uchiha Madara and his younger brother were the first to obtain Mangekyou. Madara himself did this by killing his friend, it's assumed his brother also killed a close comrade. Usage of the Mangekyou techniques drains quite a bit of a user’s chakra, more so than any other normal technique. Also as a result of Mangekyou usage, the bearer will slowly lose their vision. Madara lost his vision before his brother and sought to regain his power. To do so he removed his brother's eyes and made them his own. With these new eyes, his Mangekyou took on a combined appearance of his original Mangekyou and his brother's. These "Eternal" Mangekyou eyes returned his vision and gave him unbelievable strength. With this strength it was said Madara used Sharingan's normal ability to supress the Kyuubi and tame it. Itachi originally told Sasuke that if he gained the Mangekyou, then there would be three people who could handle it. After the time skip in the series, Hatake Kakashi revealed he too had gained Mangekyou Sharingan. Later it was revealed that Uchiha Madara himself was still alive, and was the "third" user in Itachi's statement. What part, if any, that Kakashi and Uchiha Obito's eye plays has yet to be determined. Itachi's three named Mangekyou techniques are Amaterasu, Tsukuyomi and Susanoo, all mythological deities. Kakashi's Mangekyou technique has not yet been named. The Amaterasu or Goddess of the Sun technique is generated by the right Mangekyou eye. It is a Ninjutsu technique which uses the Mangekyou form to create a powerful black fire which can burn through most anything. As it has been said that anything within the Mangekyou's vision will burn to ash if consumed by the fire. The fire itself is said to burn for 7 days and 7 nights. The fire is also regarded as the strongest of Mangekyou's physical attacks. The Tsukuyomi or God of the Moon technique is generated by the left Mangekyou eye. It is a Genjutsu technique which uses the Mangekyou form to initiate a mentally and physically harmful illusion. To utilize the illusion, the clan member will look into the eyes of his opponent and cast a Genjutsu spell on them. The spell takes place in the mind of the one affected, while the jutsu is cast the one it was cast upon is at the total mercy of the Uchiha clan member. The clan member has full control over space and time in the jutsu and can place the one affected through any hell they desire for any length desired. The technique itself only lasts for but a second in reality, but the one affected could have lasted through several days of pain. It is said only a natural born member of the Uchiha Clan can defeat it, this may mean either an Uchiha also holding the Mangekyou or one fully skilled in the three tomoe Sharingan form. The Susanoo or God of the Sea and Storms technique is generated by both Mangekyou eyes. It is a technique which uses the Mangekyou form to create a sword wielding specter which will surround the user. This specter wields a shield for defense and a blade known as the Totsuka Sword. Anyone or anything cut by the blade will be sealed away into a Genjutsu of blissful oblivion until the end of time. The third Mangekyou technique seen in the series is used by Hatake Kakashi and remains unnamed. With this technique, Kakashi forms a handseal to activate the Sharingan in his left eye and change it into his Mangekyou form. Kakashi then focuses on a point on the body of his target. The area around the target will then begin to warp and collapse in on itself, resulting in that area being quickly "sucked" out of existence and transported to another location Note: Obtaining this level of the sharingan is a lengthy and likely difficult process. The key element into achieving it would be for a bloodline-Uchiha (not an individual who has later inherited the eye) to kill his best friend. From an evaluation standpoint, HV administrative staff must unanimously agree that the slain "friend" has been legitimately played out to an extent where it is believable. Furthermore, both the fight and the relationship should at least seem 100% legitimate. If we believe the encounter or entire ordeal was simply to achieve this end, then we will, without remorse, reject the Mangekyou. Upon achieving the Mangekyou, you will be able to train 3 S-ranked eye techniques, all of which will apply wear and tear on the sharingan as it is used-- eventually leading to character blindness. Additionally, these three techniques are completely random. As it is in the manga, the Uchiha has no real decision-making power over what sort of Mangekyou he will achieve. Administrative staff will likely determine your three jutsu ahead of time. Finally, these jutsu will likely be considerably toned down from their presentation in the series (if the jutsu from the series are even open game for your character.

Bloodline Jutsu

Amaterasu - Goddess of the Sun (Heavenly Illumination) Technique

Class: Bloodline Ninjutsu Rank: S Range: Close (0m ~ 5m) Type: Supplementary Chakra Cost: High-Massive Amaterasu, named for the Goddess of the Sun, is a Ninjutsu technique which uses the Mangekyou form of the Sharingan eye to create a powerful black fire. This jutsu is generated by the right Mangekyou eye. It has been said that anything within the Mangekyou's vision will burn to ash if consumed by the fire. The fire itself is said to burn for 7 days and 7 nights. Because of the amount of chakra needed to use the technique, it can only be used on a very limited basis daily. Though it is regarded as the strongest of Mangekyou's physical attacks, usage of the ability will degrade the eye further and lead the user to blindness. Note: Amaterasu fires as a relatively fast moving projectile starting from shortly in front of the user toward the target. This technique causes severe damage to the retina, often blinding and threatening the eyesight of the caster. Due to the amount of chakra consumed, it can likely only be used effectively in battle one time.

Magen • Kyouten Chiten - Demonic Illusion • Mirror Heaven and Earth Change

Class: Bloodline Genjutsu Rank: S Range: Close (0m ~ 5m) Type: Supplementary Handseals: None Chakra Consumption: High Magen • Kyouten Chiten is a Genjutsu technique unique to the Uchiha bloodline Sharingan holders. Using the copy and counter functions of the Sharingan eye, the Uchiha clan member can stop the sensory spell cast on their body and reverse it back on their opponent. Note: Requires that the user has a fully activated sharingan.

Kamui - God's Majesty

Class: Bloodline Ninjutsu Rank: S Range: Far (10m+) Type: Attack Chakra Cost: High-Massive This doujutsu is a Ninjutsu technique which uses a form of the Mangekyou Sharingan eye to launch a long range attack. This technique may be a third Mangekyou skill in a trio named after mythological deities. The first is Amaterasu, next is Tsukuyomi. To begin Kakashi formed a handseal to change his normal three tomoe Sharingan into a new Mangekyou form. He then focused on an area of his target. The surrounding area then began to warp and collapse in on itself, quickly reducing the surround area to nothingness. The technique will thus essentially transport the focused area away to another location. The technique caused a huge strain on Kakashi, utilizing a great deal of chakra. He was able to use the technique twice in succession and then revert back to three tomoe, it is unknown how many times he could use it before total exertion. Note: This technique takes a total of 3 turns to successfully land. Line of vision must be maintained the entire time. If at any point, sight is broken, the process must begin again.

Sharingan Hypnotic Genjutsu

Class: Bloodline Genjutsu Rank: A Range: Close (1m ~ 5m), Mid (5m ~ 10m) Type: Supplementary Handseals: None (for basic) / 3 (for advanced) Chakra Consumption: Mid (for basic) / High (for advanced) This is a broadly categorized genjutsu that utilizes the Sharingan as the source for the ability. The genjutsu uses no handseals and can be used one of two ways. In both instances, the jutsu requires eye contact. On a most basic level, this is the ability used by Kakashi to influence the actions of a ninjutsu-using opponent, influencing their decisions and allowing the ninja to make it appear as though they are copying jutsu faster than the enemy can actually plan and act. A more advanced usage of the technique can create very slight illusions. These were visible as the genjutsu that Sasuke implemented against Deidara or Itachi where the Sharingan-user can modify aspects of the enemy's perception, allowing them to perceive the Uchiha ninja dying, or create bunshin-like illusions in their stead. Note: For the more advanced use of the genjutsu, used for full illusions, in this storyline handseals are required in addition to eye contact.

Sharingan Soufuusha Sannotachi - Sharingan Windmill Triple Blade

Class: Bloodline Ninjutsu Rank: C Range: Mid (5m ~ 10m), Far (10m+) Type: Attack Handseals: None Chakra Consumption: Low Sharingan Soufuusha Sannotachi is a Ninjutsu technique utilized by Uchiha clan. Using the developed vision of the Sharingan eye, the clan member hurls three Windmill Shuriken which have wire attached. While in the air the clan member can manipulate wire to make the blades circle the target, which results in the attached wire binding them.

Susanoo - God of the Sea and Storms

Class: Bloodline Ninjutsu Rank: S Range: Close (0m ~ 5m), Mid (5m ~ 10m) Type: Attack, Defense, Supplementary Chakra Cost : Massive Susanoo, named for the God of the Sea and Storms, is a technique which uses the Mangekyou form of the Sharingan eye to create a sword wielding spectral form which will surround the user. This jutsu is generated by both Mangekyou eyes. Susanoo will first form around the user as a skeleton. This skeletal form will then generate muscle and armor for battle and wield both a sword and shield. The sword is formed out of the sake in the gourd it holds, meaning the sword has no true physical form. This legendary weapon, known as Totsuka's Sword and the Sakegari (Sake Cutting) Long Sword, utilizes the main ability of the jutsu. Anyone or anything cut by the blade will be sealed away into a Genjutsu of blissful oblivion until the end of time. It is said the sword is thus the ultimate counter to Orochimaru's Kusanagi Sword. The shield is known as Yata's Mirror. It is said this shield can defend against any attack. Together the sword and shield will make the Susanoo user nearly invincible. Like other Mangekyou techniques, usage of Susanoo will damages the eyes and health of the user. Note: Susanoo takes a total of 2 uninterrupted turns of summoning before it can be called into battle. Susanoo can be sustained for just 2 turns per summon.

Tsukuyomi - God of the Moon (Moon Reader) Technique

Class: Bloodline Genjutsu Rank: S Range: Close (0m ~ 5m) Type: Supplementary Chakra Consumption: High Tsukuyomi, named for the God of the Moon, is a Genjutsu technique which uses the Mangekyou form of the Sharingan eye to generate a powerful illusion. This jutsu is generated by the left Mangekyou eye. This highly advanced technique can not be used extensively because of the toll it places on the user. To utilize the illusion, the clan member will look into the eyes of his opponent and cast a Genjutsu spell on them. The illusion takes place in the mind of the one affected, while under the jutsu the victim is at the total mercy of the user. The user has full control over space and time in the jutsu and can place the one affected through any hell they desire for any length desired. The technique itself only lasts for but a second in reality, but the one affected could have lasted through several days of torture. It is said only a natural born member of the Uchiha Clan can overcome the illusion. To counter the technique, however, Mangekyou is not required. A highly trained normal Sharingan user can break the illusion, causing the Mangekyou user to experience additional weakness from using it. Note: Ultimately this jutsu boils down to a fairly standard Genjutsu ability as far as HV is concerned. The difference is that within the domain of Tsukuyomi, the Uchiha has greater domain over how the passage of time is felt to the captive.
