About
Demon Slayer Corps: An unofficial organization not recognized by the government. Demons (Oni): Burn to death in sunlight. They roam only at night and can regenerate. They die if their heads are decapitated. Ranks: Mizunoto -> Mizunoe -> Kanoto -> Kanoe -> Tsuchinoto -> Tsuchinoe -> Hinoto -> Hinoe -> Kinoto -> Kinoe -> Hashira Kakushi: A rank for support roles. Nichirin Sword: The only sword capable of slaying demons. Bright Red Nichirin Sword: A phenomenon where a Nichirin Sword's blade turns red under specific conditions. Transparent World: A sensory state reached by those who have mastered martial arts, allowing them to see through an opponent's body and movements, drastically improving prediction and evasion. Mark: A symptom that often appears in Breathing Style users. During intense combat, a mark related to their breathing style appears on their body, similar to a demon's crest. Basic Effects: Physical abilities are enhanced to a level where they can overwhelm demons—who are normally far superior to humans—even Upper Rank demons. Naturally, the power and speed of Breathing techniques also increase significantly. Cost of the Mark: The user dies by the age of 25. Twelve Kizuki: Divided into Lower Ranks and Upper Ranks. Lower Ranks: Stronger than average demons but overwhelmingly weaker than Upper Ranks. Blood Demon Art: Special abilities that only demons can use.
