If you've found yourself searching for "how old is Asta in That Time I Got Reincarnated as a Slime," you're in good company – it’s a common mix-up between two fantastic anime universes! Let’s clear the air right away: Asta is the beloved protagonist of Black Clover, a completely separate series. He does not appear in That Time I Got Reincarnated as a Slime. Our flagship guide on offers a full explanation for any lingering questions.
But just because Asta isn't here doesn't mean we can't explore the fascinating and often complex topic of character ages within Rimuru Tempest's world! From ancient True Dragons to rapidly evolving monsters and reincarnated humans, understanding how age works in this universe adds incredible depth to its lore.
Unraveling Rimuru Tempest's Unique Timeline
Our protagonist, Rimuru Tempest, has a truly unique existence that transcends conventional aging. Before his reincarnation, he was a 39-year-old human named Satoru Mikami. However, upon being reborn as a slime in a new world, his concept of age fundamentally changed.
In his new form, Rimuru is genderless and doesn't "age" in the traditional sense, though his power and understanding grow exponentially. Discover more about and the profound impact of his past life on his present. For a complete understanding of his journey, we’ve meticulously mapped out , detailing every major milestone and transformation.
The Timeless Lives of Demon Lords and True Dragons
When we talk about age in That Time I Got Reincarnated as a Slime, some characters stand out for their sheer longevity, counting their lives in millennia rather than years. These are often the most powerful beings, whose existence predates much of recorded history.
Take for example, Veldora Tempest, a True Dragon who boasts an age of over 20,000 years. Similarly, Demon Lords like Luminous Valentine and Velzard share this ancient heritage, both also exceeding 20,000 years. Milim Nava, another formidable Demon Lord, is no less impressive at over 2,000 years old, a surprising figure given her youthful appearance. Dive deeper into and how it shapes her playful yet terrifying persona. For an exhaustive list, make sure to consult our guide on , where you'll find Guy Crimson (genderfluid), Leon Cromwell (200+), Clayman (2000+), Laplace (2000+), and others outlined. These ancient beings, along with others like Elmesia El Ru Sarion (2000+) and Karion (500+), truly define the historical backdrop of the series. If you're curious about the absolute elders, you'll want to explore for a look at those who have witnessed eons.
Evolution and Maturation: The Ages of Tempest's Forces
Beyond the immortal and the reincarnated, the diverse monster species of the Jura Tempest Federation experience age in a variety of ways, often influenced by their magical evolution. Ogres, for instance, transform through stages like Ogre → Kijin → Oni → Wicked/Divine Oni. While specific ages for many Ogre characters like Benimaru, Shuna, Shion, and Souei aren't always specified, they are generally portrayed as young to mid-adults who mature rapidly through evolution.
An interesting exception is Hakurou, an Ogre swordsman who is over 300 years old, representing a rare example of advanced age within the species. Characters like Gobta, a goblin who evolves into a hobgoblin, also showcase how species mature and develop, gaining new abilities and sometimes even changing their physical stature. From the loyal Ranga, a Direwolf who rapidly grows in power, to the formidable Geld, an Orc General, their "age" is more about their stage of development and combat experience. Uncover to learn more about how characters like Rigurd, Gabiru, Kurobee, and Zegion fit into this dynamic.
Human Lifespans and Connections to the Otherworld
While monsters and spirits dominate the power structures, human characters provide a grounding perspective on age. Shizue Izawa, a key figure in Rimuru's early journey, lived to be between 72-74 years old, an age she reached through extraordinary circumstances. This contrasts sharply with younger human characters like Mariabell Rosso, who is only 10 years old.
The presence of human characters like Hinata Sakaguchi and Yuuki Kagurazaka (43+) highlights the impact of traditional lifespans, even within a world teeming with magic. Understanding is crucial for appreciating her influence on Rimuru and the wider world.
The Enigma of the Demon Primordials and Conceptual Beings
The Demon Primordials, led by the enigmatic Diablo (whose age, like other demons, stretches back to the dawn of creation), are entities whose existence is measured in eons rather than years. Testarossa, Ultima, and Carrera, under Diablo's command, are similarly ancient and powerful. Their "age" is less about chronological time and more about their inherent power and long-standing presence in the spiritual plane.
Then there's the Great Sage, later evolving into Raphael and then Ciel. This entity is genderless and represents an evolving consciousness rather than a creature with a defined age. Its growth is purely intellectual and conceptual, continuously enhancing Rimuru's abilities.
The Full Spectrum of Ages in the Slime Universe
From the ageless True Dragons to the rapidly evolving monster races and the human lifespans in between, That Time I Got Reincarnated as a Slime presents a rich tapestry of chronological experiences.
