As A Slime-s01e01-... Fixed: That Time I Got Reincarnated

His initial panic is hilarious. He screams internally, “I don’t have a mouth!” yet manages to emote more than many human characters. This is the genius of the show—constraints breed creativity.

The episode opens not with swords or magic, but with office drudgery. Satoru Mikami, a 37-year-old unmarried construction manager, lives a quiet, lonely life in Tokyo. He’s not a hero. He’s not a gamer. He’s just… tired.

On October 2, 2018, an unassuming new anime titled "That Time I Got Reincarnated as a Slime" (or "TenSura" for short) premiered as part of the Fall 2018 broadcast season. Based on the popular light novel series by Fuse, which had already gained a dedicated following online, the first episode titled "The Storm Dragon, Veldora" needed to accomplish a massive task: introduce a protagonist who is reincarnated as a slime, establish a unique fantasy world, and convince viewers that a gelatinous blob could carry an entire series. The episode achieved all of this and more, setting the stage for a franchise that has since captivated audiences worldwide. The following is a detailed guide to that landmark first episode.

: One of the most visually memorable parts of the episode is the death and reincarnation sequence. The animation becomes "psychedelic and unique," with colorful geometric patterns and kanji symbols flooding the screen as Satoru's consciousness fades, perfectly visualizing the acquisition of his new skills.

While the first episode is considered a faithful adaptation, there are some differences. The anime is often noted for streamlining or simplifying certain scenes from the novels, focusing more on action and pacing and often making the tone slightly more light-hearted. For instance, the opening scene of the girl in the burning building, while present in some versions, is considered a more jarring and confusing addition that isn't fully explained until much later in the series.

Veldora’s roar shakes subwoofers. Rimuru’s pachi-pachi bouncing sounds are oddly satisfying. The voice acting is stellar: Miho Okasaki as Rimuru delivers a gender-neutral, soft but determined performance, while Tomoaki Maeno as Veldora chews scenery with theatrical bombast.

The episode opens in modern-day Tokyo, introducing us to Satoru Mikami. He is a 37-year-old corporate worker who is generally satisfied with his life, despite being single. This immediately sets him apart from the typical teenage shut-in protagonists found across the isekai genre. Satoru is mature, stable, and content.

Instead of fear, Satoru treats Veldora with polite curiosity. They bond over their mutual loneliness. The episode opens not with swords or magic,

: To pain, temperature extremes (heat/cold), and physical attacks.

Satoru's life comes to a sudden and violent end when a knife-wielding attacker rushes toward his younger co-worker, Tamura. Acting on instinct, Satoru pushes Tamura and his girlfriend to safety, taking the blade in his own back. This is where the "isekai" transformation begins. As he bleeds out on the sidewalk, a mysterious, clinical female voice begins listing various skills he is acquiring, such as Heat Resistance, Stab Resistance, Physical Attack Resistance, and Pain Nullification.

Several moments in this debut episode are pivotal for setting the tone and direction of the entire series.

Traditionally in games like Dragon Quest , slimes are the weakest possible enemy. S01E01 establishes that while Rimuru is physically a slime, his unique skillset makes him an apex predator.
