A medical ninja is a ninja who has learned to make use of Ninjutsu and related skills to provide medical treatment to others. It also encompasses those that, using that knowledge, have enhanced their own combat abilities.
In Naruto Manga, fields like Kinjutsu, Fuuinjutsu and Poison techniques are deeply rooted into Medical Knowledge. Orochimaru is a fair example of how Medical Knowledge can be used to achieve greater power but he isn't the only one.
In Narutobase RPG, the medical ninja is capable of healing others and himself, cure poisonings, enhance his sealing knowledge and skill, develop his regenerative abilities and even learn to use poison techniques in combat.
Medical Ninjutsu is not unlike regular ninjutsu where you use your chakra to achieve effects that you would not be able to otherwise. Most Medical Ninjutsu techniques, however, are deeply rooted into Yang Release and make perfect use of Physical Energy.
The following is the method to which a med-nin can deduce a patients ailments in order to heal them... or deduce your own ailments and heal them:
A Medical Ninja needs to start somewhere and that somewhere is detecting the issue with your patient. Shindan or diagnosis is the first step in treatment; understanding the problem. With this skill you use your hands to carefully probe a patient for problems that you might not be able to see. Contact with the patient will initially be needed but with time becomes optional. Despite this, you'll always need a close proximity between your patient and your hands. This technique is preformed by approaching the patient and slowly running both hands over his or her body, using your chakra to examine the body and looking for signs of injury that may not be visible to the naked eye. It can detect any physical alteration to the body (internal or external wounds, lesions, tumors, fractures, diseases, etc) as well as its composition (glucose levels, iron levels, antibodies, etc ) and vital signs (blood pressure, heart rate, temperature, pain levels, breathing, oxygen saturation, etc).
A student of Medical Jutsu will require several minutes to assess all the details but a medical ninja will be able to do so in mere moments. To help less experienced ninjas or to aid in complex cases, direct contact is often used as well as chakra transmiting mediums such as water, wood, etc.
Mental injuries such as psycosis, depression, bipolar disorder, etc can be determined as well. In this case, however, scanning the patients head is necessary. By scanning the various hormones, chemicals as well the electrical currents that make up the inner working of the brain, the medical ninja can detect any inbalance and to what it might be due. He cannot read minds but he can understand if there is a disease or a Genjutsu present.
Additionally, all medical ninjas can use this skill to sense the patients chakra flow. Its by sensing the chakra flow that most of the times injuries and disease are noticed and diagnosed. Ninjas have their physical being greatly intertwined with their chakra, making so that an injury in one will result in changes to the other.
Finally, after gaining mastery over medical jutsu, a medical ninja becomes even able to examine dead bodies, determining cause and time of death.
Let me just explain how Shindan works a bit better, for everyone.
The idea behind it is that you will send your chakra through another body (your hands are the main focus here and its through its tenketsu that you'll release the chakra) and then will it to return to you with the information you need. That means that it doesn't matter whether you will touch the person or not or the location of your initial scan at all; the chakra will find the root of the problem and the manifestation of it. This is the information you require.
You can use chakra transmitting mediums, such as water, to improve you diagnosis and its effectiveness. The easier it is for your chakra to enter the body of the patient and return, the more information you'll be able to attain. Water has the innate ability to assist us in transmitting our chakra to better diagnose a patient. Some justu utilise water to assist in healing, stemming from RL cultures were healing is seen as a healing element and often associated with healing.
Now, to achieve this you need advanced chakra control and practice. Too much chakra and you risk harming the patient. Too little and you might not get enough information out of it.
What skills, KGs and abilities might help the medical ninja in this procedure?
Any advanced sensory enhacement helps the ninja adquire information in a more detailed manner, faster and without needing so much time. The main examples are:
-Sharingan: the ability to see your chakra flow and is characteristics as well as the ability to gain advanced visual perception in general helps to better identify the issues with the patient.
-Byakugan: perhaps the most useful of all the abilities that can help a medical ninja, the Byakugan allows you to see inside the body, piercing through the flesh and looking at the core issue in detail. Additionally, because you can see the chakra circulatory system completely and in detail, you can gauge the extent of the damage and if it somehow has anything to do with his chakra flow.
-Rinnegan: seems to have the same/similar perception to the Byakugan and Sharingan in that it can see chakra and chakra flow, but it doesn't grant you the ability to see the chakra network and tenketsu to the same detail as the Byakugan.
-Chakra Sensing: As said above, most injuries and diseases affect the chakra flow. By being able to sense disturbances in the chakra flow of your patients you are able to better understand their nature and extents.
-Enhanced Hearing: This can help you better evaluate biological functions such as breathing, heart function, intestinal function, blood circulation, blood pressure, etc.
-Emotion Sensing: While we talk about injuries of the flesh, the medical ninja also needs to treat injuries of the mind, often associated with Genjutsu. To better do this, sensing the emotions of your targets might help greatly.
So here is the open discussion part, voice your comments, questions, concerns or anything else you might want to say about these classes.
Before one can treat patients, one needs to protect himself. In real life, medical staff use gloves, masks, etc. But for a Medical Ninja in a battlefield, that's not practical. A Medical Ninja must always be aware of becoming a victim of whatever their patient is suffering from so he needs resistance to disease. With this skill you, as a Medical Ninja, increase your natural resistance to most natural diseases and toxins as well as most man made diseases and poisons, allowing you to threat an infected or poisoned patient with a higher safety. It has no effect on diseases or poisons already affecting you though. This skill, as all others, improves as you grow in power and affords greater resistance to a wider range of diseases and poisons and can become something that you don't even need to focus to achieve.
However, there are limits. This skill will essentially provide a boost to your natural resistance to disease, poison, toxins, acids, alkaline substances, etc but will only basically provide a "shield" of sorts around you. This shield can be overcome, like all others, by overpowering it. This essentially means that you cannot use this to defend from enemy offensive techniques in the midst of battle.
If you decide to and gain Poison Mastery, allowing you to make your own Custom Poison and mastery that branch of medical arts, this skill will allow you to become immune to regular none custom poisons and to your own poison.
How is it performed?
Now, to do this, you need to focus on your chakra at its core. This, when you look at the chakra circulatory system, is the central spiral network of chakra paths thats surrounds your chakra source, normally located in your abdomen. When you focus on it, you need to visualise a growing yellow and warm aura, spreading from your core, outwards towards your skin. Its this focus and this will that will make your chakra passively aggressive towards pathogens and most natural toxins and infectious diseases. This chakra is invisible to the naked eye and doesn't go beyond the users skin. However, doujutsu might see the aura growing and expanding from the medical ninjas core.
Its this a technique?
Teikouryoku is not a technique, has no chakra cost or is otherwise performed in any way remotely similar to a Jutsu. It is a passive skill, much like diagnosis, taught in the medschool, that gets stronger with time; the more you work with it, the better it will protect you against contagious diseases and poisons.
Are there different stages to its effectiveness?
Medical Student: can maintain this skill active for a few minutes, enough to treat a single patient but needs effort and to will it to happen. Its impossible to keep active at all times.
Medical Ninja: the skill can be active for as long as he wishes and he doesn't need to dedicate any kind of mental command or focus for it to work.
Poison Master: Not only is the skill the same as the one for regular medical ninjas as it can protect the user from his own Custom Poisons and similar techniques (for example, toxic/poisonous/venomous elements) at all times.
This is just an explanation as to how you would be immune to your own poisons and then immune to cannon poison release, which is no longer a medical thing so I don't believe this lesson should be here any longer. Regardless, I'll make this lesson worthwhile by 'teaching' you the following jutsu, which you'll be able to use as soon as I move on to the next lesson.
( Iryo Ninjutsu: Doku Teikouryoku ) - Medical Technique: Poison Resistance
Chakra: ( 40 per turn )
Description: The user will raise his resistance enabling him to stop the progression of a poison, toxin or venom he might have been contaminated with after feeling its first effects. This will not cure the poisoning but rather stop its progression so the user can continue to fight, hopefully winning the fight, to then be able to treat the poisoning. This is a skill that only consumes a move when activated, passively draining chakra, focus and stamina from the user as each turn passes.
If you get infected by a poison and, like genjutsu have reasonably deduced you are poisoned/infected, you can stop any further progression of the poison past the current effects you feel. It will cost you a lot of chakra over time, however you'll learn jutsu to remove poison. Fuuinjutsu provides a quicker way to remove poison, while Medjutsu has two cannon methods to remove it.
Yeah not a very good technique, but there's another technique that makes up for it.
Kuchiyose No Jutsu (Summoning Medical Tools)
A medical ninja, regardless of his skill, will always face situations in which he'll need medical tools to treat patients. Be it to create antidotes or medicine, but to also stitch or bandage wounds, you'll always need to make sure you can access medical tools and supplies to treat patients.
*Hands out a scroll to each of you*
This technique allows a Medical Ninja to summon some of the tools of their trade. It is not practical to carry around syringes, scalpels and other tools but a scroll that can be used to summon these and other similar objects is both practical and convenient.
So as for any good summoning jutsu, you need your blood and a few kanji which you can all find in your scroll. You are expected to carry it with you at all times. It includes:
(Kuchiyose No Jutsu: Eisei Yougu) Summoning technique: Medical tools
Chakra cost: 20
Description: The medical Ninja will bite his thumb and do the summoning handseals before pressing his palm on the scroll. He will summon any of the medical tools he needs that are listed on the scroll, all or just one, depending on his own needs.
Note: This can only be used by Medical Shinobi.
List of summoning items:
メス - scalpel, sterilized
ナイフ - knife
アルコール - a bottle of 96% ethanol for disinfection
水 - a bottle of sterilized water
スポイト - syringe, sterile, for one time use only
アドレナリン - adrenaline, to be injected intravasulary, induces faster heartbeat
包帯 - bandage, sterile, 8 meters in length
血液 - a set of everything you need to draw someones blood (Sterile syringe, vacuum system and a test tube.)
温度計 - mercury thermometer, for axillary or rectal use
ベッド - a mobile bed to carry patients
バグ - bug spray, effective against all bugs, lasts for 2 turns (used in cases when your patient is having a reaction to multiple bug stings, and there are still some bugs around it, so you spray-kill them. Kills bugs up to A rank if they've been created/summoned from a jutsu like the Aburame techniques)
テント - a small tent, just enough for two people to lie in
光 - a flashlight
ガスマスク - gas mask with a bottle of oxygen that lasts 5 turns (Not 100% effective against all types of poison/gas. The purpose is to protect the user from breathing in toxic substances, keeping the lungs safe. However, if the poison gets absorbed through the pores of the skin it will still affect you).
流体 - a set to start an intravenous fluid addition line, helpful with dehydration amongst many other conditions
モルタル - mortar and pestle, chemically clean
スプーン - spoon, sterile
パテ - putty knife, metal, sterile
研究所 - a small tent. Into the walls of that house, parts of Nexus' eyes DNA have been inserted, so now it mixes Time And Relative Dimensions In Space , creating an effect of being larger on the inside then it is on the outside. Inside is an advanced ninja laboratory with everything needed to create antidotes and medicines.
So yeah, there's some things you can summon, for healing and stuff. Some nice things for WSE RP too!
Okay so this is a tricky one . To begin with, this technique does not cure a poisoning; it simply extracts a portion of the poison and prevents immediate death by delaying the ongoing poisoning. It mainly allows a medical nin enough time to prepare an antidote for the poison and to slow down the effects of a poison used against the medical nin so as to give them time to escape or prepare an antidote for themselves. A patient will still die from a lethal poisoning even if this technique is used if the poison is not treated. Truth be said this technique is less effective against highly advanced poisons that have very fast acting times.
(Iryō Ninjutsu: Doku Ekiso) Medical Technique: Poison Extraction Jutsu
Description: An advanced medical jutsu used when the user cannot make enough antidote to cope with a poison. This is used to extract a great deal of the poison from a body, and then the antidote can be administered. The user will need a medium (his own chakra or a chakra receptive medium compatible with the human body, like water) which he will insert into the patients body, using his chakra to gather the poison directly from the tissues, merging it with the medium to then remove and discard. The technique can only remove a limited amount of poison and will not negate any ongoing effects as it cannot remove poison already being metabolized/in effect. Because of this, the medical ninja will still need to administer an antidote and will need to use the technique twice to remove all of the poison from the patient.
Note: can only be used twice, each use delaying the effects of the poison for 2 turns.
The jutsu works in the way that you insert (either your chakra or another highly absorbable, chakra-reactive medium) into the patients body, where it then looks for the poison in various vital organs, and when it finds it, it binds it to it's own energy and draws it out of the body. If using your own chakra (which you will most of the time) then that chakra cannot go back into your body otherwise you'll poison yourself, you have to discard it, if you're using the previously mentioned medium you have to throw it away. The use of specific chakra receptive mediums helps to mitigate/diminish the risk of self poisoning or injury when dealing with unknown poisons and, more importantly, with corrosive ones.
Removing the poison makes it easier to heal. You remove the "inactive" poison that is circulating the patients body and hasn't yet affected any tissue. By removing that you prevent further injuries and damage into the patient. However, the poison which is already affecting the tissues needs to be dealt with with antidote. If you didn't remove the "inactive", unused one, you'd need to supply antidote for a much longer period of time and would risk losing the patient in the inbetween.
( Iryō Suiton: Suika ) - Medical Water Style: Water Mosquito
Type: Supplementary Rank: A Range: Short Chakra: 30 Damage: N/A ( -20 damage as the poison is removed ) Description: After using the Tiger seal, the user creates water mosquitoes, that can be used to nullify poison in a target's body. Designed specifically to suck out poison, the user is unable to use anything else while concentrating on the target. Despite being a healing jutsu, the several mosquitoes cause pain to the body as it heals it.
Note the damage cause by using the mosquitoes. No water source requires though it does require as much concentration/attention as the poison extraction technique. This does however nullify the poisoning much quicker though damage already caused will still have to be treated.
First of all, what would constitute a "highly absorbable, chakra-reactive medium"? Would this be some form of medical tool, or other cannon instrument we could use, or would it have to be, for example, a Custom Weapon which absorbs chakra?
The Highly Absorbable chakra-reactive medium can be Water, Wood, etc. It can be anything that reacts with chakra and is compatible with organic medium. Water was what we saw used in the manga by Sakura but you can also simply use your raw chakra. Wood is a possibility as its organic in nature and would be a nice medium for this. In theory, other elements/materials that are compatible with organic living things or that exist inside them can be used.
Is there any particular reason the technique cannot extract all of the poison? And, building on that question, if several med-nin worked together at once, would they be able to extract all of the poison? Or is the fact that we cannot extract it all tied into how poisons affect our bodies?
Poison will cling to the cells and tissues in a way that prevents you from pulling it all out without damaging the patient in one go. You need to take the first portion first, then redo the procedure to remove the remnants that might be left. In essence, you'll only be removing the poison that is "waiting to act" in the body, not the one already acting. Think of it as cleaning spilled oil on a surface. First you pass a cloth that takes the majority of the oil but there is always some left on the surface. You then pass a new cloth once again to clean whatever is left.
Would this work on other toxins aside from poison, such as, for example, venom? Or would this extract solely poison, and leave us unable to extract other deadly toxins?
We will speak about Poison, Toxins and Venoms further on but to answer your question, in terms of our RP, all 3 are cured in the same manner: remove + antidote.
What is considered an advanced poison? Considering that the technique is only B ranked, I'd assume that everything poisonous above B rank is too strong to be extracted, right?
Advanced poisons are all the custom poisons, the specific poisons. Anything not existing in real life/nature/narutoverse nature. Basically, man made poison. Poison form normal Poison Release techniques are not considered advanced. Sasori's poison is considered advanced poison though severely slow acting.
Something kinda useful, in that you'll learn some jutsu! The jutsu list has changed a bit since this handbook was made, so I've edited in a jutsu that also falls under this category of treatment. You can also use these once you've replied/completed this lesson.
Right so the last technique you learned was the Water Mosquito, so the next few are offensive based medical techniques, Chakra scapel, Strong Beam and Chaotic Mental Collision.
( Iryō Ninjutsu: Chakra no Mesu ) - Medical Technique: Chakra Scalpel
Rank: D - A
Chakra Cost: 15 - 30 ( per turn )
Damage Points: 30 - 60
Description: Chakra no Mesu is a special Ninjutsu technique used by medical ninjas. The ninja will focus chakra to their hands. This medical technique then enables the users chakra to transform into small, sharp blades. This can then be used for highly accurate incisions necessary for surgeries and anatomical dissections. Unlike regular metal scalpels, the chakra scalpel can make cuts inside the body without actually creating an open wound, limiting the risks of an infection (although it can also be used to cut the external tissues as well). The chakra scalpel can also be used offensively, although it requires great precision to be effective. Because of this requirement, using the chakra scalpel offensively is highly unusual. In heated combat, even the greatest medical-nin won't be able to exert the precision needed to make fatal cuts, but it can still effectively cut muscle tissues and tendons, rendering the target immobile. Adding to the technique's blade like quality, it also appears to give the user an increased level of durability over their chakra clad hands. The strength and effects of the technique are determined by how much chakra is put into it and how much skill and focus the user has in the technique. Its effects vary according to the targeted body though to cut through strong tissues such as bone, great skill, focus and chakra is needed. The effect can be sustained while the user focuses chakra into it.
Note: Can only be used by Canon Medical Bios or NB Medical Ninjas.
A multi rank technique which one focuses their chakra to form a blade. This blade allows you to cut the target (friendly or opponent) on the inside without cutting the outside skin. Also should it be desired, you can cut the skin to leave an opening as well. While operating, it can be used to finely cut what you need, but in the heat of battle, it can be hard to land accurate fatal blows, such as severing the organs.
On top of this, it also add durability to ones hands, as the layer of chakra provides protection while shaped as a blade.
While potentially outshadowed by other taijutsu techniques that can deal the same or greater damage, this still has uses to cut directly inside an opponent, as well as adding durability to ones hands.
For an idea on what it looks like, this is the technique that Kabuto was first seen using, or rather one of his signature techniques.
( Iryo Ninjutsu: Tsuyoi Kōsen ) - Medical Ninjutsu: Strong Beam
Range: Short - Long
Description: A high level medical technique in which the user gathers medical chakra, akin to the Shosen Jutsu technique, into his index and middle fingers, forming a dense chakra focus point. This chakra quickly changes from a light, translucent green to a heavy, bright red color as the user points his fingers outwards, unleashing a powerful chakra beam. The chakra beam, however, has different properties from normal chakra and, unlike the technique which serves as its basis, has no healing effect, quite the contrary. If it hits an enemy living organism, its aggressive nature injures the targeted tissues, creating an effect similar to a severe burn. The cells burst open as if having been hit by a high temperature, reducing themselves to a mushy pulp as the beam travels through them. If undefended, the beam can easily pierce through an enemy in a fast manner. The travelling speed of the beam is akin to that of a similar ranked lightning technique. The down side of the technique is that, when it collides with an elemental technique, it acts as a simple, concentrate chakra beam, capable of overcoming B-Rank defenses and only being negated by A-Rank ones.
Similar to the Chakra Scalpel jutsu, this is is another use of ofensive chakra, however with stronger reach. The difference being while Chakra Scalpel may be able to only cut inside the body, Strong Beam simply disintergrates tissue, as described " If it hits an enemy living organism, its aggressive nature injures the targeted tissues, creating an effect similar to a severe burn. The cells burst open as if having been hit by a high temperature, reducing themselves to a mushy pulp as the beam travels through them."
Note that if used simply as a damaging energy chakra beam, it can break through B rank elemental ninjutsu, but will be stopped by A ranked ones, and overcome by S rank ones.
( Iryo Ninjutsu: Ranshinshou ) - Medical Technique: Chaotic Mental Collision
Chakra Cost: 30
Damage Points: N/A
Description: Manipulating the chakra in their hand, the user can create an electric field to disrupt the target's nervous system. Because the brain and body communicate using electrical impulses, the user can use the field to disrupt the target's ability to move. The result is the commands to move one body part being relayed to another, making it near impossible for the opponent to move unless they have high skill and understanding of the body or with time. This effect can be achieved by making contact with the enemy, preferably near or directly on his spine (neck, lower back, etc). Contact with a single limb or body part will affect only its symmetric counterpart. The effects last for 10 turns unless countered but are short lived in high level taijutsu users ( EIG users, Taijutsu Masters )which have an unparalleled awareness of their body movement, quickly adjusting themselves to their new nervous arrangement and in medical ninjas, who possess a high level of awareness of their own bodily functions, achieving the same effect by pure control and adaptability, causing it to last 5 turns.
Another offensive medical technique, this one doesnt do damage, but can be just as deadly by prefenting a target from being able to communicate with their muscles. A touch with this technique to the users spine, preferably to the neck, can instantly paralyze an opponent rendering them unable to move. An important note that if you touch an opponents limb, say their left arm, it will also effect their symmetrical counterpart, their right arm.
These effects last 10 turns, unless they are either a taijutsu specialist, EIG user, or also have med, in which the effects will only last 5 turns, but will still most likely be long enough to be effective.
