Overview[]

Normally, Nichirin Swords can turn into virtually any color dependent on the user 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 Nichirin sword can become bright red regardless of the blade's original color. However, the blade can only stay bright red for a certain amount of time before returning to normal.

Methods[]

The bright red hue that envelops the blade is achieved through deliberate actions intended to raise the blade's temperature, fuelling the conversion of mechanical energy into thermal energy. The following three distinct methods of activation are known:

  1. Friction: Clashing two swords together with enough force that the friction generated between them produces a substantial heat buildup, causing both blades to illuminate in a bright red hue.[1][2][3]
  2. Pressure: Gripping a sword with an unwavering strength to exert immense pressure onto the metal surface. This focused pressure produces a localized heating effect, causing the blade to turn bright red.[4][5][6]
  3. Ignition: Engulfing a sword in flames with Nezuko Kamado's Exploding Blood to raise its temperature to an extreme level. The searing heat of the flames turns the sword bright red.[7] This is the only method which doesn't require a Demon Slayer Mark.

Effects[]

Bright Red Nichirin Sword (1)

The most notable effect of a bright red Nichirin sword is its ability to hamper or even completely nullify a demon's regeneration. The bright red Nichirin sword also generates extreme heat, which can cause immense pain to demons and cause them to cough up blood.[8][9] The extent of which a bright red Nichirin sword can hinder a demon's regenerative ability can be quite apparent, as seen with the likes of Hantengu and Muzan Kibutsuji himself taking around a dozen seconds to regenerate damage that would be healed instantly under normal circ*mstances.[10][11]

Bright red Nichirin swords also seem to be able to nullify the regeneration of demons that have just been decapitated, thus permanently killing them even if they managed to regrow their heads after being decapitated by a Nichirin sword. This can be inferred when Kokushibo, who had just overcome his weakness of decapitation from Nichirin swords, slowly crumbled away and was unable to regenerate despite being stabbed in a non-lethal spot by a bright red Nichirin sword.[12]

Yoriichi Tsugikuni's bright red Nichirin sword is the most potent out of all Demon Slayers, being able to burn on a cellular level and leave scars that even the Demon King himself can't heal even after centuries.[13] Furthermore, once slashed by Yoriichi's Nichirin sword, the cells in the affected region will be continuously burned for centuries.[13]
