Hiroshi Tsugikuni

**Hiroshi Tsugikuni** (次国博志 *Tsugikuni Hiroshi)* is the cultivator of Eclipse Breathing and the Eclipse Hashira (日食柱 *Nisshoku Bashira*) of the Demon Slayer Corps.

## Appearance

Hiroshi is a young woman with a relatively petite build. She has chin-length blonde hair flowing across her face. She also has blue and green eyes which reflect light.

Hiroshi wears a loose blue jacket on top of her uniform, with a belt strap across her chest and a belt across her waist. She wears a multicolored haori with a loose skirt, similar to the Insect Pillar's Tsuguko, Kanao Tsuyuri's. She also wears pinkish-red Kyahan along with a pair of zōri with blackish-grey straps.

As a child, she had long hair reaching down to her waist from birth. However, this changed when she awakened her Demon Blood after seeing a demon and fighting it for the very first time.

## Personality

Hiroshi is seen as either very happy or very sad, and there are no neutral expressions for her. She is kind and sympathetic, even feeling bad for demons, much like Tanjiro Kamado. She loves to talk to people and doesn't care about pessimistic people. She happily chats with demons, even though they are usually scared of her and try to run.

### Physical Abilities

* **Enhanced Physical Prowess:** As a member of the Hashira, Hiroshi's physique has been increased to superhuman levels through years of harsh training combined with the use of the **Total Concentration: Constant** (・ *Zen Shūchū Jōchū*?). The members of the Hashira in general have incredible movement speed, all of them have displayed the capability to use blinding bursts of speed that make it seem like they teleported to even talented swordsmen like Tanjirō Kamado. The Hashira also possesses incredible physical strength, shown when a severely weakened Kyōjurō Rengoku could hold down an Upper-Rank Demon with his bare hands, Giyū and Shinobu Kochō can leap great distances effortlessly and Gyōmei Himejima can move gigantic boulders with his bare hands. They also possess superhuman stamina and durability, being able to fight for nearly hours with severe injuries.

### Supernatural Abilities

* **Demon Slayer Mark:** In her battle against Muzan, Hiroshi awakened her Demon Slayer Mark, which appeared on the left side of her forehead. It took the form of a jagged black line of flame. Manifesting the mark also allowed her physical strength, endurance, and precision to greatly increase.
	+ **Bright Red Nichirin Blade** (く *Akaku Nichirin Tō*?): As Hiroshi fought Muzan, her Nichirin Blade turned in bright red, giving it the ability to hamper the enhanced regeneration of demons.
	+ **Transparent World** (きる *Sukitōru Sekai*?): During her battle against Muzan, Hiroshi managed to gain access to the "Transparent World". This allowed her to see the muscles, blood flow, and joint movement of her opponents.
* Special Ancestral Demon Blood: Due to her grandmother, Jiraiya Tsugikuni, having turned into a Lower Moon Demon in her time, Hiroshi possesses very little Demon Blood in her, which partly contributes to her physical strength. She can partially awaken it when feeling a very strong emotion, especially anger.

### Swordsmanship

* **Master Swordsman:** As a Hashira of the Demon Slayer Corps, Hiroshi possesses a great amount of strength and is one of the strongest Hashira.

1. **First Form: Swift Powerful Ecliptic Slash** (迅速な強力な黄道のスラッシュ *Ichi no kata: Jinsokuna kyōryokuna kōdō no surasshu) -* A powerful swift horizontal semi-circular slash aiming to cut off a demon's head.
2. **Second Form: Sun Palace, Thunderous Eclipse** (サンパレス サンダース・エクリプス *Ni no kata: Sanparesu sandāsu ekuripusu) -* Appears to be a constantly moving wave of black fire, which looks like a mix of Sun Breathing, Second Form: Clear Blue Sky and Moon Breathing, Eight Form: Moon-Dragon Ringtail.
3. **Third Form: Dark Lethal Waves of Fury** (怒りの暗黒の致命的な波 *San no kata: Ikari no chimei-tekina nami) -* Similar to Sun Breathing's Raging Sun, the user strikes the air multiple times to send a wave of powerful slashes spiraling in a large radius.
4. **Fourth Form: Fiery Ecliptic Dragon** (灼熱の黄道竜 *Shi no kata: Shakunetsu no kōdō ryū) -* This powerful attack takes the shape of a constantly shifting black dragon, similar to Water Breathing's Constant Flux technique.
5. **Fifth Form: Bold Terror-Inducing Darkness** (大胆な恐怖を誘発する闇 *Go no kata: Daitan'na kyōfu o yūhatsu suru yami*) - In this attack, the user walks towards the target slowly while there appears to be total darkness around, giving the target a false sense of safety. Once in close range, the user blinds the opponent by slashing the eyes and then repeatedly stabs the body before swiftly slicing the head.
6. **Sixth Form: Question of the Sunrise** (日の出の質問 *Roku no kata: Hinode no shitsumon)* - The user dashes from left to right, disorienting the demon and then flips 360 degrees to chop the opponent in half while simultaneously splitting them into tiny pieces.
7. **Seventh Form: Shadow Edge** (シャドーエッジ *Shichi no kata: Shadōejji)* - The user spins around in a chaotic storm-like pattern, chopping surrounding opponents into shreds.
8. **Eight Form: Spirit Dance** (精霊の舞 *Hachi no kata: Seirei no Mai* - The user swings his/her blade with such force the wind power generated acts like an extension of the blade and can be used for long-range attacks.
9. **Ninth Form: Deceiving Red Moon** (赤い月を欺く *Ku no kata: Akai tsuki o azamuku)* - The user appears to glow for a brief moment before dashing forward and slicing the enemy's head. The easiest form to master but the weakest (depending on the user's strength).
10. **Tenth Form: Shore of Life and Fire** (生命と火の岸辺 *Jū no kata: Seimei to hi no kishibe)* - A complex form requiring strong swings and complex footwork. The user holds the blade above the head while it is coated in black flames before leaping to and fro while defending and attacking. Very powerful and will stun the enemy.
11. **Eleventh Form: Heat of Appearance** (出現熱 *Jū ichi no kata: Shutsugen netsu)* - The most powerful attack. The user appears to be shrouded in darkness before a wave of black and red flames strikes the enemy. After it clears, a giant black replica of the user appears to be mimicking the user's movements, and this form then combines all the forms into one, supremely powerful one before appearing to teleport away. The user then slashes the opponent into shreds again using an improved version of Seventh Form: Shadow Edge. This move, due to its immense strain produced on the body and the power required, needs a Demon Slayer Mark and Red Blade to accomplish and is even more powerful if a user of one of Eclipse Breathing's parent styles is involved.
