What Is A Demon Slayer Mark?
A demon slayer mark is a manifestation that occurs majorly on a demon slayer’s face and sometimes other body parts. Each Mark is different owing to the user’s breathing style. These marks can only be awakened in special conditions.
The conditions are; their blood pressure should be over 200 Bpm and their body temperature should be 39° celsius. These conditions are often life-threatening and this is why only a few people can awaken their demon slayer mark.
This mark grants the user amazing Abilities. The awakening of this mark increases the powers of the demon slayer greatly. It also turns their nichirin sword bright red. This sword is very hot, which helps in inflicting more damage on the demon and it also hampers the regeneration abilities of the demons. This state, therefore, is extremely powerful and useful for any demon slayer.
Why Does The User Only Live For 25 Years?
It has been noted many times throughout history that marked individuals only live for 25 years. The reason why a marked individual doesn’t live past 25 years after the awakening of his mark has never been canonically proven or justified.
But the characters in the show have hinted at certain things. The upper moon 1 Kokushibo states that the awakening of the mark greatly decreases a user’s lifespan in exchange for granting them extraordinary power.
However, it does not mean that an individual cannot awaken the mark after he is older than 25 years of age. Gyomei managed to awaken the mark when he was much older than 25. But Kokushibo hypothesized that he would die only after a few hours because of this. His words came true as Gyomei died after a few years in his battle with Muzan, but that could be because of the injuries he sustained.
It is also never specified that the curse always happens. But according to the history of the anime, it seems every user has died except Yoriichi, but that could be because he did not awaken the mark, but was rather born with it.
