How Old Is Rimuru Tempest in Mashle? Hes Not From That Series

It’s easy to get lost in the vast and vibrant world of anime, especially when a character as iconic as Rimuru Tempest comes to mind. You might be wondering about his age, perhaps even connecting him to a different series like Mashle: Muscles and Magic. If that's what brought you here, let’s clear things up right away: Rimuru Tempest is not a character from Mashle. He hails from his own wildly popular series, That Time I Got Reincarnated as a Slime (also known as Tensura).
The confusion is understandable; both series feature powerful protagonists in magical worlds. However, Mash Burnedead relies purely on muscle and a deadpan demeanor, while Rimuru is a sentient slime with god-like abilities. So, if you came looking for Mash's age, you're in the wrong place! But if you want to know all about Rimuru, you’ve hit the jackpot.

The True Age of Rimuru Tempest: Before and After Reincarnation

Before he became the adorable, yet terrifying, slime we know, Rimuru Tempest was an ordinary human named Satoru Mikami. A 37-year-old general contractor living a rather mundane life in Tokyo, Satoru met an untimely end defending a co-worker from a knife attack. It was this fateful event that led to his reincarnation into a new world.
Upon his reincarnation as a slime, Rimuru essentially starts life anew. In his slime form, he doesn't age in the traditional human sense. Within the narrative of That Time I Got Reincarnated as a Slime, he is generally considered to be only about 2 years old (as depicted in the anime and manga adaptations) or 3 years old (in the original light novel series) by the time major events unfold. He’s also "sexless," meaning he doesn't have a biological gender, which allows him to take on various forms, often mimicking a beautiful young person or even adopting a more masculine appearance when needed. To truly understand the full scope of his journey and where he belongs in the anime multiverse, you'll want to .

The Man Behind the Slime: Personality and Leadership
