Katsumi Yamashita

**Katsumi Yamashita** (山下 (やました)  勝 (かつ) 美 (み) , *Yamashita Katsumi*?) is a Demon Slayer and the Space Hashira (夜 (よる) 柱 (ばしら) , *Yoru Bashira*?) of the Demon Slayer Corps.

## Appearance

Katsumi is a young man, fairly short and extremely stocky stature making his weight more muscle than fat. His intimidating appearance can scare some people. He has rather dark skin with eyes possessing heterochromia similar to Obanai Iguro, with his left eye being gray and his right eye being amber.

Katsumi wears a sleeveless and dark-gray version of the standard Demon Slayer uniform. Over this, he wears a haori that's split down the middle into two different patterns: the right being indigo with multiple wavy overlapping lines and the left being pure white with dark-gray flowers and leaves at the bottom. As well as this, he wears layered tabi socks along with a pair of white zōri with blue straps.

## Personality

Despite his big, intimidating, brave, and stocky appearance, he suffers from Social anxiety which makes him more a cold, aloof, cowardly, shy, clumsy, depressed, timid, weak, nervous, worried, apathetic, lonely, self conscious, sensitive person who keeps a extremely silent, mysterious, and a dark aura around social situations. He can speak few or no words around crowds or noisy circumstances. When he speaks, he speaks with a very silent and soft tone of voice which makes him more of a girlish personality. He can easily get upset or disappointed when he gets scolded or reprimands around public and cries very easily but usually, he often misunderstands words meant for conversations turns like into scolding or getting some reprimands for him. He has an extremely low self esteem which he thinks he is noting compared to others and also he thinks he is the most wrongest person in the world. Sometimes when his social anxiety worsens, he even thinks he wants to be a hikikomori (A person who doesn’t want to leave their home). This might be caused because of his past experiences while training the “Space Breathing”, he got traumatized by how harsh the training was and, his former mates were able to complete more quicker and faster than him and Katsumi was the last one to clear which leaded him to extreme sorrow and embarrassment.

When it comes to a familiar place like home or a room with few people, he becomes a friendly, enthusiastic, flamboyant, spoiled, childish, kind, blunt, approachable, funny person. He is humble, making himself, the lowest and respecting others.

He is tolerant and usually doesn’t show his anger in public but once he gets angry, he becomes an impatient, vengeful and harsh person but once his anger fuses, he regrets that he didn’t manage his anger properly and gets extremely embarrassed to see the person who he got mad at.

When it comes to training, he shows more strict and a stern personality to help improve his trainer but the truth is all of his Social anxiety personalities helps him to become a caring and a good person in his flaming heart while training others.

3 years after, he slightly changed. A dark side of himself began to show madness and impatience. Also he comes with haughtiness and arrogance after the Space slayer arc. He turns more dour, unapologetic, avoidant, victimized, and resentful due to his extremely low self esteem and his Social Anxiety is getting worse each time. He also started to have misanthropic views about humans who are living better than him. He started to extremely fear to make mistakes and failing. However his former students are supporting him to be the person he once was.
