Among the most intriguing are those who have achieved immortality, whether through supernatural means, curses, or sheer willpower. These immortal characters are often at the center of complex storylines, their prolonged lifespans allowing them to amass great power, pursue grand ambitions, or sow chaos across worlds. Here are ten of the most memorable immortal characters in anime, each with their own unique traits and motivations.
10. Sebastian Michaelis – Black Butler
Sebastian Michaelis, the demonic butler from Black Butler, epitomizes the enigmatic, all-powerful servant. Bound to serve Ciel Phantomhive as part of a sinister contract, Sebastian’s immortality and supernatural abilities allow him to perform remarkable feats. A skilled fighter with mastery over fire, his true nature is that of a demon, driven by the promise of consuming Ciel’s soul. His character blends cruelty with loyalty, adding layers of complexity to the anime’s dark narrative.
9. Frieren – Frieren: Beyond Journey’s End
Frieren: Beyond Journey’s End presents a refreshing take on immortality through its protagonist, Frieren, an elf mage who outlives her companions. Hailed as a hero for her role in defeating the Demon King, Frieren is forced to grapple with the passing of time and the mortality of those around her. Despite her near-immortal status, Frieren’s journey is one of self-discovery, as she honors the wishes of her late friends and seeks new connections in her long life.
8. Hidan – Naruto
In Naruto, Hidan stands out as a fanatical cultist who worships the god Jashin. Through brutal experiments, he achieves immortality, enabling him to recover from fatal injuries and even remain conscious after decapitation. His immortality, however, comes at a cost: his madness and violence know no bounds. Despite his resilience, Hidan meets his end in a unique manner when Shikamaru Nara outsmarts him, burying him alive and leaving him to starve.
7. Muzan Kibutsuji – Demon Slayer: Kimetsu no Yaiba
Muzan Kibutsuji is the main antagonist of Demon Slayer and the original demon. Having lived for over a thousand years, Muzan is the most powerful demon in existence, constantly seeking a cure to the sunlight weakness that threatens his immortality. His cruelty is unmatched, and he rules over his demon subordinates with an iron fist, committing atrocities to further his quest for ultimate power. His pursuit of immortality ultimately ends in defeat at the hands of the Demon Slayer Corps.
6. Sato – Ajin: Demi-Human
Sato, the main antagonist of Ajin: Demi-Human, is a leader of a group of immortals known as Ajin, who can regenerate from fatal injuries. Unlike the others, Sato rises above his kind through his military prowess and ruthless personality. A former soldier, he uses his immortality to orchestrate acts of terrorism, constantly pushing the boundaries of what is possible for an Ajin. His ability to kill and resurrect at will makes him a formidable foe, and his chilling determination to achieve his goals makes him a character to be reckoned with.
5. Yato – Noragami
Yato, a minor god in Noragami, seeks recognition and fame, desiring a shrine of his own to rival the most powerful deities in Japanese mythology. Despite his status as a god, Yato is far from infallible. His dark past as a god of calamity and his struggle for redemption form the core of his character arc. With the help of his Regalia Yukine and mortal companion Hiyori, Yato strives to forge a better future, though his immortality ensures that he must deal with the consequences of his past for eternity.
4. Alucard – Castlevania
As the son of Dracula, Alucard inherits his father’s immortality and supernatural powers in Castlevania. A skilled swordsman and vampire, Alucard is forced to confront his father after the murder of his mother. His internal struggle with his identity and his relationship with his father make Alucard one of the most tragic and complex characters in anime. Though immortal, Alucard seeks peace and redemption, often finding himself torn between duty and personal desires.
3. Dio Brando – JoJo’s Bizarre Adventure
Dio Brando, the notorious villain from JoJo’s Bizarre Adventure, is one of the most iconic immortal characters in anime. As a vampire, Dio possesses immense strength and the ability to manipulate time through his Stand, The World. Driven by his traumatic childhood and desire for ultimate power, Dio is a ruthless and charismatic antagonist, willing to sacrifice anything and anyone in his pursuit of domination. His immortality makes him an ever-present threat to the Joestar family and their allies.
2. Sukuna – Jujutsu Kaisen
Sukuna, also known as the King of Curses, is a legendary figure in Jujutsu Kaisen. Originally human, Sukuna’s immortality was achieved when he split his soul into 20 cursed fingers, each containing a fragment of his power. As one of the most powerful and feared curses in history, Sukuna’s near-invulnerability makes him a terrifying adversary. His quest for control over his vessel, Itadori Yuji, plays a central role in the series, and his actions continue to shape the fate of the jujutsu world.
1. Ryuk – Death Note
Perhaps the most iconic immortal character in anime, Ryuk is a Shinigami (death god) in Death Note. Immortal by nature, Ryuk’s role in the story is that of an observer and catalyst, setting the events of the series in motion by dropping his Death Note into the human world. Unlike many other immortal characters, Ryuk is indifferent to the moral struggles of humanity, acting purely out of boredom and curiosity. His eventual role in Light Yagami’s downfall is a stark reminder of his detached, impartial nature.
Conclusion
The appeal of immortal characters in anime lies not just in their abilities but also in the rich, often tragic backstories that shape them. Whether seeking redemption, revenge, or power, these characters provide a compelling lens through which the anime explores themes of mortality, ambition, and the human (or non-human) condition. From Sebastian’s eternal service to Ryuk’s detached observation of human chaos, these characters remain at the forefront of anime storytelling, captivating audiences with their untold lifespans and complex motivations.
