A Demon Slayer Class for Dnd 5e

Demon Slayer
The Demon Slayer Corps is as an organization dedicated to hunting and killing demons. Most members of the Demon Slayer Corps are combatants, known as Demon Slayers.
As the Demon Slayer Corps isn't officially recognized by the government, its members are forced to work in secrecy, which means that Demon Slayers cannot openly carry their swords in public. The majority of people are unaware of the existence of demons, and even if Demon Slayers were to reveal the truth about their job, they would be met with skepticism and disbelief from most individuals. Allowing Demon Slayers to openly wield swords would only incite chaos and confusion among the general population. By maintaining a low profile and avoid drawing unnecessary attention, they can carry out their duties covertly and effectively. Nevertheless, whispers of the Demon Slayers have permeated public consciousness, existing as mere folklore in the minds of some. However, when civilians encounter demons or witness a Demon Slayer engaging a demon firsthand, they come face-to-face with the reality of their existence and the truth behind the tales they've heard.
Without any support from the government or other sponsors, the Demon Slayer Corps relies solely on the resources provided by the Ubuyashiki family for its daily operations. The Ubuyashiki family's accumulated wealth, acquired through their unique gift of foresight,[6] plays a vital role in ensuring that the Demon Slayers have the necessary means and resources to fulfill their duties effectively.
History
The Demon Slayer Corps was founded approximately a thousand years ago during the Heian Era. This occurred after Muzan Kibutsuji, a distant relative of the current Ubuyashiki family, inadvertently became the very first demon. As a result, a curse befell the Ubuyashiki bloodline, causing subsequent generations to suffer from premature deaths. Seeking guidance, the Ubuyashiki family heeded the advice of a priest and established the Corps. They took on the responsibility of leading the battle against Muzan and his demons, believing that by eradicating demons from the world, they could break the curse that plagued their bloodline.
In the centuries that followed the establishment of the Corps, they achieved moderate success in eliminating some of the demons Muzan created, but no one was able to reach the Demon King himself. However, during the Sengoku era, the tides turned. A talented swordsman named Yoriichi Tsugikuni joined the Corps after his wife was slain by a demon. He imparted his knowledge of Total Concentration Breathing onto the Hashira of the Demon Slayer Corps. He also endeavored to teach them a Breathing Style known as Sun Breathing, but despite their efforts, none of them could match Yoriichi's level of mastery, so he modified the techniques to suit their individual strengths. These modifications formed the foundation of the first Breathing Styles, from which numerous other styles emerged as branches. The swordsmen of that era were already highly skilled, and when combined with the Breathing Styles, their power increased exponentially. Furthermore, distinct Marks began to appear on the bodies of these swordsmen, further enhancing their abilities. This era of Demon Slayers came to be known as the Golden Age, as they displayed incredible prowess in vanquishing demons with astonishing force and almost eradicated all demons.
Hashira
Hashira is the highest rank which Demon Slayers can obtain in the Demon Slayer Corps. The Hashira are regarded as the most skilled and feared combatants in the entire organization, protecting humanity against more dangerous threats that cannot be handled by other Demon Slayers.
The Hashira, in accordance with their great strength, hold the highest authority in the organization, second only to the Corps leader, Kagaya Ubuyashiki, and later, Kiriya Ubuyashiki.
The Hashira are all assigned a specific region that they are required to patrol, usually to gather information about the demons inhabiting said area and to improve their swordsmanship. They are also deployed on missions only if lower-ranking members are unable to complete it.

Total Concentration Breathing
Total Concentration Breathing is a breathing technique which involves expanding one's lungs to intake as much air as possible, accelerating one's blood flow and heartbeat while increasing their inner body temperature, resulting in their bones and muscles becoming more excited.
As an action, you may enter Total Concentration for a total time of 1 minute or until you lose concentration (as if you were concentrating on a spell). To do this you must be able to freely breathe.
While in Total Concentration Breathing you may replace your attack action with one of your Breathing Techniques.
You may enter Total Concentration a number of times equal to your Constitution Modifier (minimum of 1), and regain all uses of this feature at the end of a long rest.

Starting at 3rd level, you gain the service of a crow sent by the Demon Slayer Corps to watch over you. The crow assumes the form and game statistics of a raven, and it always obeys your commands, which you can give telepathically while it is within 100 feet of you.
While perched on your shoulder, the crow can’t be targeted by any attack or other harmful effect; it can’t take damage; and it is incapacitated.
The crow speaks and understands the same languages you do.
In combat, you roll initiative for the crow and control how it acts.
The crow doesn’t require sleep. While it is within 100 feet of you, it can awaken you from sleep as a bonus action.
The crow vanishes when it dies, if you die, or if the two of you are separated by more than 5 miles.
At the end of a short or long rest, you can call the crow back to you—no matter where it is or whether it died—and it reappears within 5 feet of you.

You also can hold your breath for twice as much time as you could previously.
Extrassensory Perception
Extrasensory Perception grants the user a "sixth sense" which enables them to sense the paranormal or supernatural. Most Demon Slayers, are able to sense the presence of demons from an extreme distance.
As an action, you can open your awareness to detect such presences. Until the end of your next turn, you know the location of any undead, fiend or monstrosity within 60 feet of you. You know the type of any being whose presence you sense, but, unless you have met this creature before, not its identity. Within the same radius, you also detect the presence of any place or object that has been fiddled with by such creatures.
You can use this feature a number of times equal to 1 + your Wisdom modifier. When you finish a long rest, you regain all expended uses.
Total Concentration Breathing: Constant
Total Concentration: Constant is a Total Concentration Breathing state during the morning, noon, and night, and even while asleep that advanced Demon Slayers, can constantly maintain. There is an immense difference in strength, speed, and stamina between someone who can maintain Total Concentration Breathing at all times and someone who cannot. By doing it every minute of the day, one's physical fitness drastically improves.
At 12th level you can maintain your Total Breathing Concentration for an indefinite amount of time. You also receive advantage for maintaining your Total Concentration.
Recovery Breathing
At a more advanced level, Total Concentration Breathing is also capable of slowing down the circulation of poison in the bloodstream and even clotting wounds from severe injuries. By focusing on every inch of the body and raising the accuracy of one's Breathing, one can spread their sensitivity throughout one's body and detect and even heal hidden internal wounds they may have.
At 12th level while you are concentrating in your Total Concentration Breathing and below half of your hit point maximum, you can as a bonus action, recover 1 + your Constitution Modifier of hit points or end an effect on yourself that is causing you to be poisoned.
Slayer Mark
Demon Slayer Marks are irregularities on the skin that resembles a birthmark and which commonly appears on the face or another visible location of the body of Demon Slayers that resemble the crests of demons. Each Demon Slayer possesses a unique pattern to their Mark which appear to be based on the Breathing Style they utilize. The Mark can only be awakened under very specific conditions and grant special abilities while also enhancing pre-existing traits of the bearer. Once awakened, the Mark can disappear after a period of time along with its effects, though it can be re-activated by meeting the same conditions.
Starting at the 15th level, your Slayer Mark manifests itself on your body after the following conditions are met:
- Your current hit points needs to be below one third (rounded down) of your hit point maximum
- You must not be affected by any harmful conditions
- You must be in the middle of combat
- You must be concentrating on Total Concentration Breathing
You can choose the color, shape and placement of your mark on your body. While your mark is manifested you recieve the two following benefits:
- You may use two different Breathing Techniques in a single attack action.
- You gain resistance to bludgeoning, piercing and slashing damage.
When you exit your marked state you must succeed on a Constitution Saving Throw of DC20 or become paralyzed until the end of your next turn.

Crimson Red Blade
Normally, a demon slayer’s swords come into virtually any color dependent on the material and their Breathing Style. However, there is one color that cannot be normally accessed: a shining bright red. Unlike other colors, a bright red sword has special properties and can only be accessed by Demon Slayers who have awakened the Demon Slayer Mark. Moreover, any sword can become bright red regardless of the blade's original nature. However, the blade can only stay bright red for a certain amount of time before returning to normal. The bright red hue that envelops the blade is achieved through deliberate actions intended to raise the blade's temperature, fueling the conversion of mechanical energy into thermal energy.
Beginning at the 17th level, while in your marked state, you may use your action to turn any non-magical melee weapon you are wielding into a Crimson Red Blade. While the weapon is a Crimson Red Blade it receives the following traits:
- It becomes a +3 weapon of any type it were previously
- Any breathing techniques made using this weapon now deal radiant damage.
- A creature hit by an attack made by this blade reduces it’s hit point maximum by the amount of damage it received on the attack. If a creatures hit point maximum is reduced to 0 by this weapon, it is disintegrated and can only be revived by nothing short of a Wish Spell.
The weapon stays as a Crimson Red Blade for 1min, until your marked state ends or if you let go of the weapon. The weapon is destroyed when its Crimson Red state ends.

Transparent World
Demon Slayers that have awakened the Mark can utilize a special form of ocular extrasensory perception that alters their vision, allowing them to perceive other living beings as if they were transparent, only being able to see the inner workings of their bodies.
Beginning at the 18th level, you may as a bonus action enter the Transparent World for 1min. While on the transparent world you can determine how physically well a creature is, thus allowing you to know how many hit points a creature has remaining. You also receive advantage to all checks made to understand a creatures nature, mannerisms, feelings and thoughts.
You may use this a number of times equal to you Wisdom Modifier (minimum of 1), and regain all uses of this feature at the end of a long rest.
Anata
The Anata is an esoteric and mysterious state of being in which one completely erases their presence, will to fight, bloodlust, anger, hatred, malevolence, drive and animosity. Once in this state, the user's behavior becomes incredibly tranquil and focused, often being compared to that of a plant. Although it does not enhance one's own combat prowess, it is implied to be regarded as the highest state of physical combat one can achieve.
At the 20th level, when you begin your Total Concentration Breathing you can choose to instead enter a state of Anata. While in your Anata state you receive all benefits related to your Total Concentration Breathing but it does not require concentration. Additionally, for all effects considered by you as harmful, you are considered an object and you can’t be detected or seen by any special senses (such as Darkvision, Truesight and Tremor Sense)
While in your Anata state you can’t speak nor understand any spoken languages, you immediately fail any Intelligence saving throws and immediately succeed any Wisdom Saving throws.
You may end the Anata state at any moment by using a bonus action. You can use this feature only once per long rest.
Breathing Styles
All known Breathing Styles currently taught within the Demon Slayer Corps are derived from Sun Breathing, the first one ever created. The majority of known Breathing Styles mimic a certain element of nature and replicates it with the user's movements, techniques and abilities.
New Breathing Styles are always being created to suit a Demon Slayer's combat needs, which results in new weapons being utilized in demon hunting. Such Breathing Styles embody a bigger variety of concepts, like animals, plants and emotions. When utilizing a Breathing Style, users automatically visualize themselves manipulating the subject behind their style, making it seem as if they were using magic, though those that are less apt and proficient in their style will visualize less of it than one who is.
Water Breathing
Water Breathing is a Breathing Style that mimics water, specifically the flow, flexibility and adaptability of the liquid and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques involve the user bending their body, arm and weapon in a fluid motion to match the movements of rushing or flowing water. Users also visualize themselves seemingly creating and manipulating water when unleashing its techniques.
1st, 2nd and 9th forms:
2nd level Water Breathing techniques
- Water Surface Slash The user crosses their arms and generates enough momentum to release a singular, concentrated, horizontal slash. Make an attack with a melee weapon at a creature within the weapons range. On a successful hit, you deal an additional 1d6 slashing damage. This damage increases by 1d6 in the 5th, 8th and 11th level. The damage die used in this technique becomes a d8 if the target is an undead, fiend or monstrosity.
- Water Wheel The user leaps forward into the air and performs a front flip, releasing a singular vertical slash in a circular motion. You run up to 10ft straight into any direction of your choosing and jump high into the air (the maximum height of this jump equals to 5 + your Dexterity Modifier). While in mid-air you may make one attack with a melee weapon at a creature or object within range. On a successful hit, you deal an extra 1d6 + your Wisdom modifier of slashing damage. The maximum height of the jump increases by 5ft at 5th, 8th, and 11th level. The damage die used in this technique becomes a d8 if the target is an undead, fiend or monstrosity.
- Splashing Water Flow, Turbulent The user changes their footwork in a way that minimizes the landing time and surface needed when landing, allowing the user to move without limits. Ideal when fighting in a place with no solid foothold. Your movement speed increases by 10ft until the end of your next turn. At 5th level, your speed increases by 10ft and you become unaffected by difficult terrain. At 8th level, your speed increases by 10ft and your movement do not provoke opportunity attacks. At 11th level, your speed increases by 10ft and you ignore any effect that would impede your movement in any way.
3rd, 4th and 5th forms:
5th level Water Breathing techniques
- Flowing Dance The user swings and bends their blade in a winding motion along with their body and dances in a flowing pattern, slicing everything in its path. You freely walk up to 20ft. You may target one attack at two different creatures that enter the range of this weapon while you are moving through this skill. The amount of creatures that can be targeted increases to three at the 11th level. All attacks deal an additional 1d6 slashing damage if the target is an undead, fiend or monstrosity.
- Striking Tide The user performs a multitude of motions in a flowing fashion to release multiple consecutive slashes. Make two attacks with a melee weapon at a creature within the weapons range. The amount of attacks increases to three at the 11th level. All attacks deal an additional 1d6 slashing damage if the target is an undead, fiend or monstrosity.
- Blessed Rain After the Drought The user changes the grip on their sword and decapitates the opponent in a single flowing strike that causes little to no pain. It is a “sword strike of kindness” used when the enemy willingly surrenders. You make a melee weapon attack against a creature within the weapons range, this attack only hits if the targeted creature willingly accepts to take it. This attack is an automatic critical hit and deals double the damage it normally would, as if the targeted creature is vulnerable to it. When you attack a creature that has at least one head, you cut off one of the creature's heads. The creature dies if it can't survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn't have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.

The damage die used in this technique becomes a d12 if the target is an undead, fiend or monstrosity.
11th form
14th level Water Breathing technique
At 14th level you learn the final and most potent defensive technique of the Water Style. This unique technique differs from the all others for being a response to an enemy attack, as such you use it as a reaction to an incoming ranged spell, effect or attack while in your Total Concentration Breathing.
- Dead Calm The user ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with their blade.

If the effect would target other creatures in addition to you, they are unaffected as well.
