Step into the vibrant, often chaotic, world of That Time I Got Reincarnated as a Slime, where a simple salaryman's unfortunate demise leads to an extraordinary new existence as a humble slime. This Isekai phenomenon has captivated audiences with its rapid-fire plot, thrilling battles, and a cast of characters so compelling you can't help but get invested. But beyond their incredible powers and evolving forms, one question frequently sparks curiosity: how old are these powerful beings?
In a realm where species can evolve from a basic Ogre to a formidable Wicked Oni, and where dragons can live for millennia, age isn't just a number—it's a testament to experience, power, and often, a source of profound mystery. Unlike typical human lifespans, the creatures of the Jura Tempest Federation, and indeed the entire world, operate on vastly different timelines. This guide delves into the intricate concept of age for the key figures of That Time I Got Reincarnated as a Slime, revealing surprising truths and highlighting the diverse lifecycles that shape this fantastical universe.
The Protagonist's Paradox: Rimuru Tempest's True Age
Our beloved protagonist, Rimuru Tempest, is the ultimate example of how age can be deceptive in this world. Formerly Satoru Mikami, a human who met an untimely end, Rimuru reincarnated as a genderless slime. While they possess the memories and intellect of a 37-year-old human, their physical existence as a slime is remarkably young—typically between 3-4 years old in the anime's timeline. This unique dichotomy allows Rimuru to combine a mature, strategic mind with a youthful, adaptable monster body, making them a truly singular leader. To truly understand this central figure, you'll want to .
Ancient Powers: The Timeless Beings of the Slime World
When we talk about "power" in the Slime universe, we're often talking about beings whose lifespans stretch far beyond anything a human can comprehend. These are the foundational forces, the ancient entities who have shaped the world for eons.
True Dragons and Demon Lords: Millennia of Might
At the pinnacle of longevity and raw power stand the True Dragons and some of the oldest Demon Lords. Consider Veldora Tempest, Rimuru's first and most powerful ally, a True Dragon whose age easily surpasses 2000 years. His sister, Velzard, is even older, boasting an age of 20000+ years. Similarly, Demon Lords like Milim Nava and Luminous Valentine also fall into this ancient category, both clocking in at 2000+ and 20000+ years respectively. These beings carry the weight of countless centuries, making them wise, formidable, and sometimes volatile. To fully grasp their profound influence and ancient histories, you can .
Evolutionary Journeys: Ages of the Monster Kingdom
One of the most fascinating aspects of That Time I Got Reincarnated as a Slime is the concept of evolution. Many species, particularly the monsters who ally with Rimuru, undergo significant transformations that not only enhance their power but can also subtly affect their perception of time and maturity.
The Ogre and Oni Tribes: Maturity Through Evolution
The Ogre tribe, for instance, can evolve into Kijin and further into Oni, such as the Wicked Oni. While the exact ages for many Ogres like Benimaru, Shion, Shuna, and Souei are not explicitly stated by the series creator, they are generally presented as being in their young to mid-adult stages. Their evolution grants them immense power and a deeper understanding of the world, making their "maturity" more about their evolved state than simple chronological age. An exception is Hakurou, an Ogre (likely Kijin) who, at 300+ years old, has lived well beyond the average Ogre lifespan, embodying decades of wisdom and combat experience.

Enigmatic Lifespans: Daemons and Unique Monsters
Beyond the clear-cut categories, some characters possess unique origins and lifespans that defy easy categorization, adding another layer of complexity to the concept of age in this world.
Diablo and the Demonic Realm
Diablo, one of Rimuru's most devoted and terrifying followers, is an Arch Daemon. While his exact chronological age isn't provided in human terms, daemons exist across vast stretches of time, often making them exceptionally old by human standards, even if their appearance suggests otherwise. His existence is tied to a desire for profound understanding rather than a linear progression of years, showcasing a different kind of ancient wisdom.
Gobta and Ranga: Growth and Loyalty
Even seemingly younger characters have surprising depths. Gobta, the goofy goblin who transformed into a hobgoblin, maintains a childlike appearance but has undergone significant development, exhibiting unexpected intellect in crucial moments. His "age" is less about years and more about his growth within Tempest. Ranga, Rimuru's loyal wolf-dog companion, also defies simple age definitions. As a unique Tempest Wolf, his powers and bond with Rimuru are more defining than a birthdate, though he exhibits typical dog behaviors that endear him to fans. For those who want to understand these compelling characters better, .
Mortal Years: Humans and Dwarves
While many of the most powerful beings boast immense ages, not all inhabitants of this fantasy world are immortal or ancient. Humans and Dwarves adhere to more familiar lifespans, offering a grounded perspective amidst the fantastical.
Human Lifespans and Unique Circumstances
Characters like Hinata Sakaguchi, a powerful human knight, and Chloe Aubert, a young human girl, represent the more conventional understanding of age. However, even human lifespans can be dramatically altered. Shizue Izawa, for example, lived to be 72-74 years old, an extended lifespan due to her unique circumstances as an Ifrit host. Yuuki Kagurazaka, while seemingly younger, is listed at 43+, indicating a potential for extended life or hidden history.
The Dwarven Kingdom: Longevity and Wisdom
Dwarves, while not immortal, are known for their longer lifespans compared to humans. King Gazel Dwargo, a formidable and respected ruler, is noted to be 300+ years old, embodying centuries of dwarven wisdom and experience. These characters remind us that even within more conventional species, age can signify vast differences in knowledge and power. To truly appreciate their roles, .
Beyond the Numbers: The True Measure of Power
In That Time I Got Reincarnated as a Slime, age is rarely just a number. It's an indicator of species, evolution, experience, and the very fabric of existence. Whether it's the ancient wisdom of a True Dragon, the rapid growth of an evolved monster, or the profound journey of a reincarnated slime, each character's age—or lack thereof—contributes to their unique power and role in the unfolding narrative. Understanding these varied lifespans helps us appreciate the intricate world-building and the diverse tapestry of beings that make the Jura Tempest Federation so compelling.
