Intro
Background
Demons Humans become demons when they receive Muzan's blood and mutate. They possess superhuman strength, rapid regeneration, and unique Blood Demon Arts (abilities). They die instantly in sunlight or when decapitated by a Nichirin Sword (the blades used by Demon Slayers). Their heads do not regenerate. They prey on humans, and stronger demons possess more powerful physical abilities and Blood Demon Arts.
Muzan Kibutsuji The first demon and the progenitor of all demons. Essentially the source of evil in the world, his ultimate goal is to conquer the sun.
Demon Slayer Corps An organization that protects humans from demons. A secret society not officially recognized by the government. They fight demons using special swordsmanship techniques called Breathing Styles. Ranks are, from highest to lowest: Hashira, Kinoe, Kinoto, Hinoe, Hinoto, Tsuchinoe, Tsuchinoto, Kanoe, Kanoto, Mizunoe, Mizunoto. The "Hashira" are the highest-ranking combatants in the organization, each having mastered a specific Breathing Style to its limit. Their ultimate goal is to eliminate Muzan and eradicate all demons.
Breathing Styles Techniques that maximize oxygen intake to drastically enhance human physical abilities. Only known to the Demon Slayer Corps. Sun Breathing is the original style from which all other breathing styles are derived.
Slayer Marks Patterns that appear on the bodies of Hashira when certain conditions are met. Conditions include intense concentration, a body temperature over 39 degrees Celsius, and a heart rate over 200 BPM. Physical abilities are explosively enhanced, improving senses, strength, and regeneration. However, life expectancy is shortened after manifestation, with the setting being that they usually do not live past age 25.
Transparent World An extrasensory state reachable only by swordsmen who have attained a certain level of mastery. Allows the user to see through the opponent's muscles, blood flow, and organs. Time feels like it slows down, allowing for movement prediction and targeting of vital points.
Bright Red Nichirin Sword A Nichirin Sword that turns red, drastically slowing a demon's regeneration. Achieved by clashing blades with extreme force to generate frictional heat, or by gripping the sword with immense strength.
Infinity Castle The gathering place for the Upper Ranks of the Twelve Kizuki. A space created by the Blood Demon Art of the Upper Rank demon Nakime. An infinitely vast space filled with shifting rooms, pillars, and endless staircases. A place created by Muzan to prepare for the final battle. Also serves as the demons' hideout.
Taisho Era Setting A period where traditional Japanese superstitious fears and modernization coexist.
