Best Demon Slayer Characters, Ranked by Impact and Power

8. Giyu Tomioka — The Water Hashira 

• Key Traits: Stoic, loyal, tormented 

• Debut: Episode 1 / Chapter 1 

Giyu is more than just the stoic swordsman who gave Tanjiro and Nezuko a chance — he’s a man burdened by survivor’s guilt and a constant feeling of unworthiness. His connection to Sabito and Makomo, the fallen students of Urokodaki, haunts him. That emotional weight humanizes Giyu and shows how even the strongest can be crushed by past regrets. 

Why he’s ranked here: While not always in the spotlight, Giyu’s quiet strength and pivotal role in shaping the Kamado siblings’ journey earn him a place among the greats. 

7. Zenitsu Agatsuma — The Thunder That Sleeps 

• Key Traits: Cowardly, loyal, surprisingly heroic 

• Debut: Episode 4 / Chapter 6 

Zenitsu’s evolution from a whiny coward to a courageous protector is one of the most satisfying in Demon Slayer. His battle against Kaigaku during the Infinity Castle arc — where he invents the Seventh Form of Thunder Breathing — marks a turning point. And let’s not forget his brave defense of Nezuko despite his fears. 

Why he’s ranked here: His comedic relief masks a deeply relatable character arc about facing inner fears and becoming someone you’re proud of. 

6. Kyojuro Rengoku — The Flame Hashira 

• Key Traits: Charismatic, inspirational, honorable 

• Debut: Episode 44 / Chapter 21 

Rengoku’s flame burned bright and fast. His fierce battle with Akaza in Mugen Train remains one of the most emotionally devastating and visually stunning fights in anime history. Rengoku’s unwavering spirit became a torch of hope for the younger generation of demon slayers. 

Why he’s ranked here: Though his time was short, his influence was massive. His legacy still resonates in the hearts of Tanjiro, Inosuke, and even fans. 

5. Kokushibo — The Fallen Legend 

• Key Traits: Complex, tragic, fearsome 

• Debut: Episode 45 / Chapter 99 

Once a revered swordsman and brother to Yoriichi, Kokushibo (formerly Michikatsu Tsugikuni) fell into darkness in pursuit of strength and immortality. His clash with the Hashira in the Infinity Castle reveals a tormented soul who abandoned humanity yet never found peace. His moon-breathing forms are terrifying and elegant. 

Why he’s ranked here: Kokushibo isn’t just a villain — he’s a cautionary tale about envy, legacy, and the cost of obsession. 

4. Nezuko Kamado — The Sun-Conquering Demon 

• Key Traits: Compassionate, powerful, symbolic 

• Debut: Episode 1 / Chapter 1 

Nezuko is the emotional heart of the series. From resisting her demon urges to shielding humans with her life, her transformation is nothing short of revolutionary. Her ability to withstand sunlight — the ultimate weakness for demons — shifts the tide in the war against Muzan. 

Why she’s ranked here: She represents hope — a bridge between humanity and demons. Her silence speaks louder than words. 

3. Yoriichi Tsugikuni — The Demon Slayer God 

• Key Traits: Gentle, unmatched, mythical 

• Debut: Episode 45 / Chapter 99 

Yoriichi isn’t just the most powerful demon slayer — he’s the embodiment of purity and purpose. His invention of the Sun Breathing style and near defeat of Muzan centuries ago laid the foundation for the Demon Slayer Corps. Even in flashbacks, his presence shakes the narrative. 

Why he’s ranked here: Without Yoriichi, there would be no path to victory. He is the legend upon which all others stand. 

2. Tanjiro Kamado — The Soul of the Story 

• Key Traits: Kind, determined, empathetic 

• Debut: Episode 1 / Chapter 1 

Tanjiro’s strength doesn’t just lie in his swordsmanship — it’s his unbreakable spirit. His empathy toward demons like Rui and Akaza showcases a depth rarely seen in shonen protagonists. During the Infinity Castle arc, his evolution into a fierce warrior while retaining his humanity is nothing short of inspiring. 

Why he’s ranked here: He’s not just the hero — he’s a beacon of what it means to fight without losing yourself. 

1. Muzan Kibutsuji — The Perfect Monster 

• Key Traits: Intelligent, ruthless, chilling 

• Debut: Episode 7 / Chapter 13 

Muzan is evil personified — calculated, manipulative, and terrifyingly efficient. His backstory as a dying man desperate to survive adds a disturbing layer of realism. In the Infinity Castle, his desperate struggle to maintain control and his fear of the sun highlight his hypocrisy and desperation. 

Why he’s ranked here: Without Muzan, there is no Demon Slayer. His existence shaped every tragedy, every hero, and every battle.
