You're starving. Honestly, if you were Nakajima Atsushi, kicked out of an orphanage with nothing but the clothes on your back and a persistent hallucination of a tiger, you'd probably be eyeing the nearest river too. That’s how Bungo Stray Dogs ep 1 starts. It doesn't give you a slow burn. It gives you a frantic, starving teenager and a man floating downstream with his legs poking out of the water like some bizarre piece of driftwood.
That man is Osamu Dazai.
If you haven't seen the series produced by Studio Bones, you might expect a grim, historical drama. After all, these characters are named after legendary Japanese authors. But the first episode, titled Fortune is Unpredictable and Mutable, flips that expectation immediately. It’s weird. It’s funny. It’s unexpectedly gorgeous. Most importantly, it sets a tonal blueprint that most supernatural action anime struggle to maintain for even half a season.
The Chaos of Meeting Dazai and Kunikida
Atsushi is desperate. He’s literally contemplating a life of crime just to get a bowl of chazuke. Then he "saves" Dazai. Dazai, who is mildly annoyed at being rescued from his latest suicide attempt, is the perfect foil to Atsushi’s frantic energy.
Enter Doppo Kunikida.
Kunikida is the guy with the notebook and the rigid schedule. He’s the straight man to Dazai’s eccentricity. The dynamic between these three in Bungo Stray Dogs ep 1 is what actually hooks people. It’s not just the powers. It’s the fact that Dazai is a genius who refuses to take anything seriously, while Kunikida is a professional who is constantly one step away from a stress-induced aneurysm.
When they take Atsushi to a restaurant, the kid eats thirty bowls of chazuke. It’s a gag, sure. But it also highlights the trauma Atsushi is running from. He’s been told he’s worthless his entire life. He’s been discarded. In the middle of the comedy, there’s this sharp, biting undercurrent of rejection that defines Atsushi’s character arc for the next five seasons.
Breaking Down the Man-Eater Myth in Bungo Stray Dogs Ep 1
The plot of the first episode revolves around a "man-eating tiger" that has been terrorizing the area. The Armed Detective Agency—a group of individuals with supernatural abilities known as "Gifts"—is on the case. Dazai recruits Atsushi to help, mostly by offering him a reward he can't refuse.
They end up in a warehouse at night. It’s atmospheric. Studio Bones uses a lot of wide shots here to emphasize how small Atsushi feels.
Then comes the twist.
The tiger isn't following Atsushi. Atsushi is the tiger.
This is the big reveal of Bungo Stray Dogs ep 1. His ability, "Beast Beneath the Moonlight," is triggered by the moon. He doesn't even realize he’s doing it. He just wakes up in different places, clothes torn, with no memory of the carnage. It’s a classic literary trope—the monster within—reimagined through the lens of early 20th-century Japanese literature.
Dazai handles the transformation with terrifying ease. He uses his own ability, "No Longer Human," which nullifies any other Gift through physical touch. One tap on the forehead and the massive, glowing tiger becomes a sleeping teenager again.
Why the Literary Names Actually Matter
For some, the names are just flavor. For others, they are the whole point. Kafka Asagiri, the creator of the manga, didn't just pick names out of a hat.
- Osamu Dazai: The real-life Dazai wrote No Longer Human, one of the most famous novels in Japanese history, which deals heavily with alienation and suicidal ideation.
- Atsushi Nakajima: The real author wrote The Moon Over the Mountain, a story about a man who turns into a tiger because of his own pride and isolation.
- Doppo Kunikida: A poet and novelist known for his naturalist style and his focus on the "ideal."
In Bungo Stray Dogs ep 1, these aren't just Easter eggs. They inform the very DNA of the characters' powers and personalities. If you know the books, the show becomes a meta-commentary. If you don't, it’s still a top-tier shonen-seinen hybrid with incredible animation.
Visual Storytelling and the Bones Aesthetic
Studio Bones (the same studio behind Fullmetal Alchemist: Brotherhood and My Hero Academia) went all out on the art direction here. There’s a specific color palette in the first episode—lots of warm oranges and deep purples. The character designs by Nobuhiro Arai are sharp. Dazai’s bandages, Kunikida’s glasses, Atsushi’s lopsided belt—everything feels intentional.
The action isn't just "hit the bad guy." It’s stylistic. When Dazai activates "No Longer Human," the screen fills with blue light and floating text from the actual manuscript of the book. It’s a visual flex that tells the audience: "This isn't your average battle anime."
The pacing of the episode is surprisingly brisk. It manages to introduce the world, the power system, three main characters, and a major plot twist in roughly 24 minutes. It’s a masterclass in pilot episodes. You leave the episode not just knowing what the show is about, but wanting to know why these people do what they do.

Common Misconceptions About the Series Start
A lot of people go into Bungo Stray Dogs ep 1 expecting a dark detective noir. It’s easy to see why. The title sounds gritty. The first scene involves a suicide attempt.
But the show is much funnier than people expect.
The tonal shifts can be jarring for some. You’ll go from a heartbreaking flashback of Atsushi being abused at the orphanage to Dazai making a dumb joke about a "double suicide" in the span of thirty seconds. It’s a specific "vibe." If you can’t get on board with the slapstick comedy, the emotional beats might feel disconnected. However, for most fans, this contrast is exactly what makes the series work. It treats the characters' trauma with weight, but it doesn't let that trauma drown the story in misery.
Another misconception is that you need a degree in Japanese literature to enjoy it. You don't. At its core, the first episode is about a kid finding a place where he belongs. That’s universal. The literary stuff is just the "bonus content" for the nerds in the back of the room.
Setting the Stage for the Port Mafia
While the first episode focuses on the Armed Detective Agency, it subtly hints at the darker world lurking beneath Yokohama. The warehouse, the deserted streets, the fact that the "police" aren't the ones handling the tiger—it all points to a power vacuum.
We don't meet the Port Mafia (the primary antagonists) in the very first episode, but their presence is felt in the way Dazai and Kunikida operate. They aren't heroes in capes. They are specialists. They are "stray dogs" who have found a pack.
Actionable Insights for New and Returning Viewers
If you’re watching Bungo Stray Dogs ep 1 for the first time, or if you’re doing a rewatch to catch up on the latest seasons, keep these things in mind:
- Watch the backgrounds. The signs in the streets and the books on the shelves are often direct references to the authors' real-life bibliographies.
- Pay attention to Dazai’s eyes. Even in the comedy scenes, there’s a coldness there that pays off massively in later seasons (especially the Dark Era arc).
- Don't skip the credits. The ending theme, "Namae wo Yobu yo" by Luck Life, is a perfect emotional anchor for the series and reinforces the theme of "calling out a name" to find identity.
- Check out the real books. If a character's power interests you, read the source material. Reading No Longer Human or The Moon Over the Mountain completely changes how you view the character dynamics in the anime.
The genius of the first episode is how it builds a bridge between high-brow literature and high-octane anime. It’s a weird experiment that shouldn't work, yet it’s become one of the most beloved franchises in the medium. Atsushi’s journey from a starving orphan to a key player in a supernatural war starts with a simple bowl of chazuke and a man stuck in a river.
Now that you've refreshed your memory on the beginning, the best move is to track the recurring "tiger" motif through the first season. It’s not just a power; it’s a representation of Atsushi’s self-loathing. Watching how he slowly learns to control it, rather than fear it, is the real heart of the story. If you've only seen the first episode, you're just scratching the surface of what Yokohama has to offer.
