Demon Slayer: 8 Characters Who Could Lead Their Own Series

by

The world of Demon Slayer is incredibly rich and detailed, going far beyond just Tanjiro’s story. While Tanjiro is central to the plot, many other characters have compelling backgrounds, motivations, and personal struggles that could stand on their own. These stories sometimes even happened years before the main events of the series and have had a significant impact on how things unfold.

These characters aren’t just fan service; they have rich, complex backstories and inner lives. They’re full of mysteries, struggles, and emotional depth, making them strong enough to carry their own stories. If Demon Slayer ever expands beyond its main plot, these characters are perfectly suited to lead new series.

8. Lady Tamayo

Tamayo played a vital, yet often unseen, role in the fight against Muzan. She uniquely weakened him in a way no weapon could, making her an essential figure in the story. Her intelligence, composure, and strong moral compass allowed her to make a huge impact while remaining largely behind the scenes.

A show centered on Tamayo could explore her transformation into a demon, the heartbreaking events that followed, and her difficult path to finding forgiveness. Seeing her fight against Muzan’s control, struggle with her demonic instincts, and ultimately sacrifice herself for others would create a deeply moving and complex story with shades of gray.

7. Kokushibo

Although the manga explains Kokushibo’s past, it only touches on his incredibly long life as a demon. His story is particularly haunting because he used to be the second-most powerful Demon Slayer, making his fall from grace a compelling ‘what could have been’ moment in the series.

His story could delve into his life after becoming a demon – how he adjusted, justified his choices, and ultimately rose to become Muzan’s most powerful follower. What makes him compelling is his internal struggle, his rivalry with Yoriichi, and the slow burn of his growing jealousy.

6. Gyomei Himejima

Gyomei’s story is already one of the most compelling and well-developed in the series. Though widely considered the strongest Demon Slayer currently active, much about his past remains unknown. We still need to learn more about his life before the orphanage, the devastating events that shaped him, and the quiet resolve that drives him.

An arc focusing on Gyomei’s past would explore his training with his Master and how that shaped his strong sense of discipline, faith, and focus – ultimately explaining who he is today. Gyomei’s ability to accept things and take responsibility, a trait that sets him apart from characters driven by anger or goals, could add a fresh and unique emotional layer to Demon Slayer.

5. Muzan Kibutsuji

The Demon Slayer series focuses on Muzan, but his backstory remains largely a mystery. It would be fascinating – and terrifying – to explore his complete history: how he gradually lost his humanity, the centuries-long quest for immortality that drove him, and the creation of the numerous demons he commands.

I’m really excited by the idea of exploring Muzan’s backstory! Imagine seeing him as a human, grappling with the fear of death – that would be incredible. But what really gets me is the thought of watching his descent, seeing his personality and humanity slowly slip away as he transforms into the Demon King. It would be such a powerful and tragic arc!

4. Inosuke Hashibira

Inosuke is a fan-favorite character known for his wild and energetic personality. But beneath the surface, he has a sad past. He grew up completely isolated in the mountains, learning to survive on instinct rather than being taught by others.

A dedicated series could explore Inosuke’s wild upbringing, detailing how he created his unique breathing style through self-teaching, and how living in isolation shaped his worldview. Knowing his difficult birth and past would make his attempts to fit in during the main story much more believable for fans. His story would be a mix of humor, violence, and quiet, internal growth.

3. Kyojuro Rengoku

Rengoku’s life was dramatic and impressive, much like he would have described it himself, and many fans wish there was more of his story to explore. He grew up emotionally distant from his father, one of the most powerful Flame Hashira, forcing him to become self-reliant. Despite this, he overcame incredible challenges, defeating a formidable demon and even rescuing Mitsuri from a lesser-ranked one.

Despite facing numerous challenges, Rengoku rose through the ranks to become a Hashira on his own merit, earning the admiration of both friends and foes. He was a skilled teacher, as evidenced by his training of Mitsuri, who also became a Hashira, demonstrating his exceptional strength and abilities. Even while exhausted from a prior fight, Rengoku proved a formidable opponent to Akaza, an Upper Moon Three demon. A continued story about Rengoku could explore his journey to becoming a Hashira, his battles against the Lower Moon demons, and the repeated tests of his unwavering optimism.

2. Akaza

I’ve noticed a really interesting dynamic with Akaza and his fans. People seem to both love and hate him! He’s admired for being incredibly disciplined, strong, and respectful – especially for his rule about never harming women. But then, he’s also deeply disliked because he was the one who killed Rengoku. It’s that very contradiction, that mix of admirable traits and terrible actions, that makes him such a compelling character, I think.

After learning about Akaza’s difficult past, many viewers grew to sympathize with him. His internal conflict and the remnants of his humanity, despite centuries of being a demon, could easily be explored in a series focusing on his life before becoming a demon.

1. Yoriichi Tsugikuni

Yoriichi is undoubtedly the strongest character and Demon Slayer in the entire series. His power was so immense that even Muzan, the main villain, acknowledged him as a formidable opponent. A story centered around Yoriichi would be incredible and incredibly popular.

Yoriichi’s inner turmoil stemmed from a deep loneliness, the guilt of failing to protect his family, and the burden of possessing a strength no one could comprehend – all he truly desired was a simple, peaceful existence. It’s a cruel irony that his brother achieved the tranquil life Yoriichi craved, while he himself became the strongest. This isn’t a story about battles, but about the isolation of being unmatched and alone at the peak of one’s life.
