That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken) stands as a titan of the "Isekai" genre. While many stories in this category follow a predictable path, Episode 1, titled "The Storm Dragon, Veldora," set a unique tone that captured millions of fans worldwide. It wasn't just another fantasy rebirth; it was the beginning of a nation-building epic led by the unlikeliest of heroes: a blue blob of jelly. The Mundane End of Satoru Mikami
The story begins in modern-day Tokyo. We meet Satoru Mikami, a 37-year-old corporate worker who is generally content with his life, despite being single. He is portrayed as a kind, protective senior colleague. This characterization is crucial because it establishes his altruism—the very trait that leads to his "death."
While meeting a junior colleague and his fiancée on the street, a random assailant rushes them with a knife. Satoru pushes them out of the way and takes the fatal blow. As he lies dying on the pavement, his final thoughts are processed by a mysterious, robotic voice known as the "Great Sage." The Logic of Reincarnation
One of the most brilliant aspects of the S01E01 script is how it handles the transition. Instead of a magical goddess appearing in a void, Satoru’s internal monologue during his final moments dictates his new form:
Resistance to Heat/Cold: He felt burning and freezing while dying. Stab Resistance: He died from a puncture wound. Self-Regeneration: He bled out and wished for more blood.
The Slime Form: Because he joked about being a "sage" due to his age and lack of romantic experience, he was granted the "Great Sage" and "Predator" skills.
He wakes up not in a human body, but as a Slime. At first, he is blind and deaf, spending what feels like weeks simply bouncing around and eating magical herbs and ores. Meeting the Storm Dragon: Veldora That Time I Got Reincarnated as a Slime-S01E01-...
The episode shifts from a solo survival story to a high-fantasy adventure when Satoru stumbles into the presence of Veldora, the Storm Dragon. Trapped in a "Unlimited Imprisonment" seal for 300 years by a Hero, Veldora is a massive, terrifying creature who turns out to be surprisingly lonely and "Tsundere" (aloof but kind).
Their interaction is the heart of the premiere. Satoru uses his "Great Sage" ability to perceive the world through magicules, allowing him to finally "see" the dragon. Instead of fleeing in terror, Satoru treats the dragon like a friend. This leads to a historic pact:
A Shared Name: They decide to share a family name to prove their bond.
The Birth of Rimuru Tempest: Veldora grants the Slime the name "Rimuru," and Rimuru gives them both the surname "Tempest."
The Ultimate Solution: To free Veldora, Rimuru uses his "Predator" skill to swallow the entire dragon (and his prison) so they can analyze the seal from the inside. Why Episode 1 Worked
The premiere succeeded because it subverted expectations. Usually, Slimes are the weakest monsters in RPGs (like Dragon Quest). By making the Slime the protagonist and giving him the "Predator" skill—an ability that allows him to gain the powers of anything he consumes—the show turned the power scaling on its head.

The episode ends with Rimuru leaving the cave, now brimming with the magical power of a True Dragon, ready to face a world that has no idea what is coming.

The major differences between the Anime and the Light Novel. Which part of Rimuru's journey
It sounds like you’re looking for a long-form article or detailed analysis based on the keyword “That Time I Got Reincarnated as a Slime - Season 1, Episode 1: The Storm of Fate, Veldora…”
Below is a comprehensive deep-dive article covering the first episode, its impact, world-building, character introductions, and why it remains one of the most iconic isekai premieres in modern anime.
As Satoru’s consciousness fades, a mysterious voice begins listing “Unique Skills” in his mind. No gods, no explanations—just a detached system interface. This minimalist approach to reincarnation is refreshing. No grand welcome, no goddess. Just pure, confusing data. The Voice in the Void As Satoru’s consciousness
Satoru wakes up. He can’t see, can’t move his limbs, and realizes he’s in a dark, damp cave. When he attempts to speak, a single word echoes: “Ribbit?” No—wait. It’s “Slime.”
Episode 1 is surprisingly cinematic. The cave’s bioluminescent crystals, Veldora’s scale texture, and Rimuru’s gooey physics are rendered with loving detail. The studio avoids overusing CG, keeping the dragon entirely hand-drawn for weight and presence.
On October 1, 2018, That Time I Got Reincarnated as a Slime (often shortened to TenSura) premiered its first episode, titled “The Storm of Fate, Veldora.” At first glance, the premise sounded absurd—a 37-year-old salaryman dies and is reborn as a gelatinous blue blob in a fantasy world. Yet within 24 minutes, this episode shattered expectations, delivering heart, humor, and a surprisingly philosophical take on death and rebirth. It wasn’t just another isekai; it was the beginning of a cultural phenomenon.
This article breaks down Episode 1 scene by scene, analyzes its masterful pacing, introduces the core dynamics between Rimuru Tempest and the Storm Dragon Veldora, and explains why this first episode remains a gold standard for the genre.
Pacing of Death
Satoru’s death is very abrupt. Some viewers may feel the emotional impact is sacrificed for quick progression into the fantasy setting.
Predictable Power Scaling
While the slime concept is unique, the “Predator” skill is essentially a cheat code. The episode hints that Rimuru will become overpowered quickly.
Veldora is a magnificent subversion. He’s a dragon of catastrophic power—his mere presence once flattened nations—yet he behaves like a lonely, melodramatic chuunibyou (adolescent delusions of grandeur). He greets Satoru with a booming laugh, then immediately asks, “Are you here to kill me? Or be my friend?”
Their conversation lasts nearly ten minutes of screen time—an eternity in anime pacing—yet it never drags. Why? Because the dialogue reveals two lonely beings finding companionship.
