Is Rimuru a boy or girl?

One of the most common questions that new fans of That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken manga) ask is about Rimuru’s gender. After all, he starts as an ordinary man in Japan, then gets reincarnated as a slime in another world, and eventually takes on a human form that looks very different from his original self. It’s no surprise that this confuses people. So let’s dive into it together: is Rimuru a boy or a girl?

Rimuru’s life before reincarnation

Before becoming Rimuru Tempest, he was a man named Satoru Mikami, a 37-year-old office worker in Japan. Satoru was very much male, living a relatively ordinary and lonely life until he was tragically killed during a stabbing incident. This death set the stage for his reincarnation in a fantasy world.

So, Rimuru’s origins are clearly male. But things change once he gets reborn.

Rimuru’s slime form

When Satoru first wakes up in the new world, he is reborn as a slime, a creature with no gender, no real biological features, and a very flexible body. At this stage, Rimuru is technically genderless. He doesn’t have a body that can be classified as male or female. Instead, his form is entirely neutral.

This is the first sign that Rimuru’s gender is going to be a more fluid topic compared to other characters in the series.

Rimuru’s human form

Later in the story, Rimuru gains a human form through a series of skills and evolutions. This form is often mistaken for female because of the soft facial features, slim build, and long blue hair. Many characters in the series even comment on Rimuru’s beauty, sometimes assuming Rimuru is a girl at first glance.

But here’s the key: Rimuru’s human body was created to be a perfect vessel, free from the limitations of biological gender. It is technically genderless, even if it looks somewhat androgynous. That’s why fans often debate whether to think of Rimuru as male, female, or both.

How Rimuru identifies

Even though Rimuru’s body is genderless, his personality and memories come from Satoru Mikami, who was male. Because of this, Rimuru often thinks of himself as a man, though he doesn’t place much importance on the label. He even jokes about it from time to time.

This makes Rimuru an interesting protagonist because he embodies both his human identity and his new existence in a completely different body. He isn’t strictly tied to being male or female, and that flexibility adds to his charm as a character.

Why the confusion matters in the story

The fact that Rimuru’s gender is ambiguous is not just a fun debate among fans. It actually plays into the themes of the series. Rimuru’s role is to unite people of different races, species, and backgrounds into one nation, Tempest. By existing outside of traditional categories like gender, Rimuru represents someone who transcends boundaries.

This is why so many characters are drawn to Rimuru. He isn’t limited by what he used to be, and he doesn’t judge others by superficial traits either. His neutrality makes him a leader whom everyone can respect.

How the anime and manga show Rimuru’s gender

In both the anime and manga, Rimuru’s appearance leans toward a more feminine style. His human form is elegant, with big eyes and smooth features. This naturally leads to the “Is Rimuru a girl?” question popping up in almost every discussion.

However, if you pay attention to the way Rimuru talks, thinks, and refers to himself, you’ll notice the personality is still rooted in Satoru’s male identity. This balance is exactly what makes Rimuru unique.

What the author has said

According to the original light novel and interviews, Rimuru is officially described as genderless in body. However, mentally, he carries the memories and sense of self from his past life as Satoru. This means that while Rimuru doesn’t technically have a biological sex anymore, he leans toward identifying as male.

It’s also worth noting that this ambiguity is intentional. The creator wanted Rimuru to be a character who could be relatable and appealing to everyone, regardless of gender.

Why fans love this aspect of Rimuru

Part of Rimuru’s popularity comes from how fluid and open his identity is. He’s powerful without being intimidating, kind without being naive, and visually appealing in a way that crosses traditional gender boundaries.

This has made Rimuru a beloved character for fans who appreciate representation that doesn’t fit neatly into one box. It’s a refreshing twist on the typical isekai protagonist.

Where to learn more about Rimuru

Both provide details that go beyond the anime and help fans understand Rimuru’s character on a deeper level.

So, is Rimuru a boy or a girl? The answer is neither nor both. Rimuru started life as a man, was reborn as a genderless slime, and now has a human form that looks androgynous. While his body no longer fits traditional categories, his mind and identity are still rooted in the male life he once lived as Satoru Mikami.

In the end, Rimuru’s gender is less important than who he is as a character: a leader, a protector, and someone who constantly defies expectations. Maybe that’s why so many fans find him so fascinating. Rimuru isn’t defined by labels, and that makes his story even more universal.
