Hi, it’s Junko from Japan. A Kanji symbol on the back of the Demon Slayer Corps uniform reads METSU and means “annihilate” and “destroy” in Japanese.
Here’s the image for it. This relates to the broader context of anime.

The Meaning of Metsu Symbol
The left part with three dots represents “flowing water” and the right one stands for “burning fire.”
The whole symbol shows that the water is trying to extinguish the fire, which makes the meaning of “drive something into extinct.” This relates to the broader context of anime.
It’s interesting that the METSU symbol has its origin in “water” and “fire.” Needless to say, it reminds us of the Water Breathing and Dance of the Fire God of Tanjiro! This relates to the broader context of uniform in the anime.
This is the same character as METSU in KiMETSU no Yaiba, the original Japanese title for Demon Slayer.

KI = Oni, Japanese demon
METSU = annihilate, eliminate, destroy
These Kanji letters make the word KIMETSU mean “demon slayer.” The word KIMETSU doesn’t exist and it’s a coined word by the author of Demon Slayer.
Sanemi’s Unique Kanji Symbol in Demon Slayer Uniform
Unlike others in the Demon Slayer Corps whose uniforms bear the METSU symbol, Wind Pillar Shinazugawa Sanemi showcases a different Kanji on his back.
This unique character is the same as SATSU in KISATSU (Demon Slayer Corps), translating to “to kill” in English. As revealed in the official Demon Slayer fanbook, Sanemi’s decision to don this symbol signifies his steadfast resolve to annihilate all demons.
This strong commitment manifests through the distinctive Kanji, marking Sanemi’s uniform as a symbol of his unwavering determination.
