Shinzui Kosshi

## Portrayal

**Shinzui Kosshi** is a supporting character in Demon Slayer: Blade of the Night. He is the first and current Bone Pillar.

## **Appearance:**

Shinzui is a frail, sickly boy with paper-white skin and caved cheeks. His hair is light tan, draping down on his face messily. Shinzui always looks like he is unwell, or simply pained. His eyes are also extremely light colored and foggy, making it hard to discern where he's looking at in particular.

Shinzui wears a traditional Pillar Uniform, with a dark red and white haori, the white parts of it forming a pattern vaguely resembling a spine and ribs, while the dark red intermediates the "rib" parts of the pattern

## **Personality:**

Shinzui's a gloomy, quiet teen, speaking very rarely, and when doing so, he is often rude or simply dismissive. Whenever forced to talk due to work, he has a tendency to be extremely curt. It is unknown if this behavior is intentional, or if he just lacks knowledge of most social norms.

Shinzui has, however, spoken his piece of mind about, and to Ryo. He seems invested in the boy's growth, or at least doesn't want him to go down a bad path. It can be inferred Shinzui sees himself as weak, or at least saw himself as such, potentially suffering some sort of bullying or abuse in the past to strengthen his poor confidence.

Shinzui, while not looking airheaded, often appears to be lost.

## **Synopsis:**

Nothing is currently known about Shinzui's past. It is, however, implied he learned the Bone Breathing from someone else.

## **Abilities:**

**Immense Strength:** Shinzui has displayed his strength during his conversation with Ryo, when the sheer strength of his slash blew away the clouds in the nearest vicinity.

**Immense Speed:** It is currently unknown how fast Shinzui is, but it can be inferred that he is quite fast.

**Total Concentration Breathing:** As a Pillar, Shinzui has mastered Total Concentration Breathing a long time ago.

**Demon Slayer Mark:** While not shown, Shinzui must have unlocked his Demon Slayer Mark, as it is a requirement for becoming a Pillar

## **Fighting Style:**

Master Swordsman: Shinzui is supposedly powerful, as he is a Pillar. It can be inferred he is very competent at using a sword.

### **Breathing Style:**

**Bone Breathing** *(Hone no Kokyu)*: Shinzui has learned and mastered the Bone Breathing, being the current Pillar and training a new generation of users.

#### **Techniques:**

There are no currently known Bone Breathing techniques.

## **Equipment:**

**Nichirin Sword:** Shinzui has a Nichirin Katana as his main weapon. It is unknown if it is modified at all.

## **Familiars:**

**Abaramaru:** Shinzui's crow Abaramaru is a plump, fat crow that overeats almost constantly. Due to this, while competent, it is very slow.

## **Battles:**

Shinzui has had no on-screen battles as of yet

## **Trivia:**

* Shinzui's name can be directly translated into "Essence/Spirit", or the "Marrow/Core" of something. [Kosshi], meanwhile, means "Skeleton/Essential".
* Shinzui, despite looking so frail, eats constantly, to the point where he has no favorite food, nor does he have something he dislikes to eat.
* Regardless of that, he has low blood pressure.
