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.

Yamanaka Clan

Clan Jutsu

Shinranshin no Jutsu - Mind Derangement Technique

Class: Clan Ninjutsu Rank: B Range: Close (0m ~ 5m), Mid (5m ~ 10m) Type: Supplementary Handseals: 3 Chakra Consumption: Mid Shinranshin no Jutsu is a Ninjutsu technique which is used to confuse the targets body into attacking a nearby ally. The ninja will form the needed hand seal and then send their spirtual energy of confusion at his opponent. Though the opponent is mentally aware of his action, he is unable to stop his body from carrying out the attack. Note: Restricted to the Yamanaka clan. The ability duration is 3 rounds. That is, to the end of the caster's turn two turns later.

Shintenshin no Jutsu - Mind Body Change Technique

Class: Clan Ninjutsu Rank: C Range: Close (0m ~ 5m), Mid (5m ~ 10m) Type: Supplementary Handseals: 1 Chakra Consumption: Mid Shintenshin no Jutsu is a Ninjutsu technique originally used for spying. The ninja forms the needed handseals and then projects their spirit out of their body into their target. This can be another ninja or an animal. Unfortunately the spirit flies in a straight line at a slow speed. If the target moves and avoids the incoming spirit, the ninjas body falls lifeless until the spirit can find its way back to the body several minutes later. Because of the risk involved, the ninja must be very careful. When used in conjunction with a binding technique the chance of success greatly increases. While inhabiting the body of their opponent, the target still remains in their mind but their mental processes are forced aside as the ninja takes control. However if the target has strong mental fortitude, they can overpower the intruder and force them out of their body. Also while in the body of their target, if the ninja takes sudden physical damage, their original body will be hurt as well. Note: Restricted to the Yamanaka clan. While it is theoretically possible to "mentally overpower" the intruder, there is no adequate measurement for such a quality. As a result, if caught in the jutsu, you're caught. The abiility duration is 2 rounds. That is, to the end of the caster's turn two turns later.

Shintenkugutsu Juin no Jutsu - Mind Puppet Change Curse Seal Technique

Class: Clan Ninjutsu Rank: C Range: Close (0m ~ 5m), Mid (5m ~ 10m) Type: Supplementary Chakra Consumption: High Shintenkugutsu Juin no Jutsu is a Ninjutsu technique that allows the Yamanaka clan member to place the mind of the victim into a puppet rather than their own body. After transferring his body into that of a puppet, Fuu's body will become defenseless. Fuu will manipulate it to throw a weapon at the victim ninja. Should the ninja catch the weapon and launch it back into the puppet, the curse tag on the puppet will activate and the victim will find their mind in that of the puppet. Because of the curse seal, the victim will be unable to manipulate the puppet's body. Fuu himself will change places with the victim and take control of their body. Like normal Shintenshin, Fuu will be unable to inflict injury on the victim's body without also being injured himself. For this reason, Fuu can create a situation where his victim's body is hurt but he is not. He can do this by binding the victim's body so they have no chance of escape and then putting them in a situation where harm cannot be avoided after he leaves their body moments before. A skilled enough ninja can detect Fuu's presence in their comrade's body and end the jutsu before Fuu can complete his goals. Note: This jutsu requires the aid of another skilled ninja (chuunin A - Jounin +) to end the jutsu before the user hurts (kills) him/herself in the process of harming the opposition. Additionally, this technique is said to be kept secret even among Yamanaka clansmen. It's unsure exactly what tasks must be undergone to achieve it.
