However, his peaceful life is shattered when a Demon slaughters his entire family. His little sister Nezuko is the only survivor, but she has been transformed into a Demon herself!

## **Terminology**

**Breathing Styles:** Breathing Styles are techniques and move sets passed down to swordsman most commonly used to combat Demons enhanced physical attributes. All breathing styles derive from **Sun Breathing** the original breathing style created by and used by Yoriichi. Breathing Styles commonly have a element or something of that nature to represent that style. Common examples of this are Water Breathing, Flame Breathing , Wind Breathing , Thunder Breathing , etc. Breathing Styles have pros and cons with different forms as well as different quantities of forms. These forms are the different techniques that comprise each Style. Breathing Styles are most effective when they fit the slayers fighting style and body type because of this new Breathing Styles are creating very often deriving from other Breathing Styles.

**Concentration Breathing:** Concentration Breathing is very key to fighting on the same level (physically) as Demons. Concentration Breathing is a technique slayers use by breathing in as much oxygen as possible while transferring it throughout the body to gain a unhuman like physical attributes. Concentration Breathing amps ones endurance as well, being able to transfer oxygen to parts of the body in need or that are lacking is a key way to stay in the best possible shape while fighting. Not only does Concentration Breathing help offensively in battle it helps defensively as well. Concentration Breathing allows users to slow down the blood circulation which can aid in slowing down the speed a poison traveling through the body or even slow down the rate of blood loss.

* **Total Concentration Constant:** Total Concentration Constant is a more advanced form of Concentration Breathing. Once mastered Total Concentration Constant turns Concentration Breathing from a technique to a state. Total Concentration Constant allows the user to use Concentration Breathing 24/7. This trains the body to be in a state of constant Concentration Breathing so the body is always in peak physical condition.

**Blood Demon Art:** Higher-level Demons, such as the Twelve , possess supernatural talents or abilities that are unique to each Demon. After getting enough strength from ingesting enough humans, demons develop them from Muzan Kibutsuji's extraordinary blood. As a result, all Blood Demon Arts use their own blood as a source of energy. Unlike Demon Slayers Breathing Styles Blood Demon Arts vary with some being more battle-oriented than others.

**Slayer Mark:** The "Mark" Of the slayer appears on the most talented of the corpse. This "Mark" is remarked to be a mysterious birthmark and or tattoo that resembles the crests of the demons. These marks give a massive boost in statistics for the tradeoff being a substantial portion of their life. There are ways to avoid death through the curse, as shown by Yoriichi and Kokushibo. Through unknown means, Yoriichi was able to live to be 80ish years old, however, this could be due to being born with it unlike others who had to awaken it. Kokushibo, on the other hand, avoided dying from the curse by becoming immortal as a result of turning into a Demon. It is still possible to awaken the mark after a Demon Slayer is older than 25, evident in Gyomei activating it and receiving the benefits without dying immediately. Kokushibo surmised that due to this unique situation, Gyomei would die within a few hours of activating it. Though Kokushibo's prediction came true, it is unknown if Gyomei's death was a result of the curse or his injuries from the final battle against Muzan. Due to the curse's inconsistency, it is possible that it's simply superstition. However, there is nothing that comprehensively disproves it either, so it's just as likely that the curse does truly exist. The Demon Slayer Mark can only appear in Demon Slayers that survived the life-threatening conditions of having a heart rate over 200 bpm and a body temperature over 39° Celsius (102.2° Fahrenheit). The prerequisite in unlocking it is that an individual born with the mark is present. The Demon Slayer's mark also has the ability to act as a catalyst, and spread from the original user to other strong Slayers, such as the Hashira, through resonance, granting them Demon Slayer Marks of their own.

**Bright Red Nichirin Sword:** Nichirin Swords can turn into virtually any color dependent on the user and their Breathing Style, however, there is one color that cannot be accessed, which is a bright red color. This color was first discovered by Yoriichi Tsugikuni when he became a Demon Slayer due to his Sun Breathing. In fact, it is a category of Yoriichi's gifted powers and abilities, which is meant to hamper the regeneration of demons. The bright red blade could only be unlocked by those with Demon Slayer Marks, as well as incredibly strong Demon Slayers, like the Hashira. The method which it is accessed varies between known users, for Tanjiro Kamado and Yoriichi Tsugikuni, it naturally activated when they engaged in combat, though the former discovered it through Nezuko Kamado setting his katana ablaze and has more trouble in turning it red, especially after his partial demonification by Muzan Kibutsuji's hand. Some of the known users, namely Muichiro Tokito and Obanai Iguro, they accessed it through focusing all of their strength and power on their katana, using the "grip strength of a vise" as described by Obanai Iguro, which he surmised from Muichiro Tokito himself. The other users accessed it through the clashing of their weapons, the friction, heat combined with their superhuman strength and Demon Slayer Mark, turned their Nichirin Sword bright red.

* **Anti Regeneration** The main and only special ability of bright red blades is to hamper or can even nullify the regenerative and healing abilities of demons, which is meant to mimic the sun's effect on them. This even slowed down the instant regeneration of Muzan Kibutsuji, to the point it took several seconds to heal a sliced off arm, which would heal in less than a split second under normal circumstances. When Muichiro Tokito stabbed Kokushibo with his bright red blade, Kokushibo described it as "searing his insides" which dealt an incredibly significant damage to the Upper Rank, and even caused his flesh to crumble away in the spot that Muichiro stabbed.

**See Through World:** Demon Slayers that have awakened the Demon Slayer 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. Most notably, users are able to perceive the flow of blood, breathing, muscular contractions and joint movements of the creature they are looking at. Potentially, one can use the Transparent World's power to see inside an enemy's body as a way to predict and evade their opponent's attacks, as well as to find openings for their own strikes.

* Additionally, the user is able to perceive the world around them as if it was in slow-motion thus dramatically increasing their movement speed and reflexes. Due to the varying circumstances of their awakening, the specifics of how a user accesses the Transparent World is currently unknown.
