Introduction
The mysterious and dangerous world created by Akihito Tsukushi has captivated fans through its manga and anime adaptations. With Made in Abyss: Binary Star Falling into Darkness, players finally got the chance to plunge directly into the terrifying depths of the Abyss themselves. Developed by Chime and published by Spike Chunsoft, this 3D action RPG offers a dark, uncompromising look at what it truly takes to be a Cave Raider.
While the game captures the intense survival mechanics and body horror mechanics known to the franchise, its narrative is split into two distinct experiences: a retelling of the original story and an entirely original canon-adjacent plot. In this guide, we break down the complete narrative structure, character arcs, and thematic twists found in Made in Abyss: Binary Star Falling into Darkness.

The Narrative Structure: Two Modes, Two Journeys
To fully understand the story of Made in Abyss: Binary Star Falling into Darkness, you must understand how the game presents its narrative. The game is divided into two main gameplay modes:
- Hello Abyss: A short, tutorial-focused narrative mode that retells the beginning of the anime and manga series.
- Deep in Abyss: The main campaign featuring an original storyline, a custom protagonist, original characters, and a much darker exploration of the deep layers.
Hello Abyss: Riko and Reg's Beginning
The game opens with Hello Abyss, which acts as both an introduction to the world and an extended tutorial for fundamental game mechanics. Players take control of Riko, a young orphan residing at the Belchero Orphanage in the town of Orth, situated on the edge of a colossal crater known as the Abyss.
During a routine scavenging expedition in the First Layer (Edge of the Abyss), Riko is saved from a dangerous creature by a mysterious robotic boy whom she names Reg. After discovering that her mother, the legendary White Whistle Lyza the Annihilator, may still be alive at the bottom of the crater, Riko decides to make an illegal descent into the Abyss. Reg joins her to recover his lost memories. This mode follows their journey through the early layers, ending shortly after their encounter with the formidable White Whistle, Ozen the Unmovable, at the Seeker Camp in the Second Layer.
Deep in Abyss: The Original Dark Tale
Once players complete the introductory mode, they unlock Deep in Abyss, which contains the heart and soul of the game's story. Instead of playing as established characters, players create their own customized Cave Raider, stepping into the boots of a fresh recruit arriving at Belchero Orphanage years before or concurrent with the main events of the series.
Rising Through the Delver Ranks
The original story centers around your custom protagonist and a close-knit group of fellow orphan recruits: Tika, Raul, and Mey. Together, these young aspirants dream of becoming legendary White Whistles.
The narrative tracks your character's progression through the official Delver whistle rankings:
- Bell / Red Whistle: Novices restricted to exploring the relatively safe First Layer.
- Blue Whistle: Adepts permitted to descend into the treacherous Second Layer (Forest of Temptation).
- Moon Whistle: Experienced raiders capable of venturing into the Third Layer (Great Fault) and Fourth Layer (Goblet of Giants).
- Black Whistle: Master delvers allowed into the Fifth Layer (Sea of Corpses).
As you complete quests, gather relic artifacts, and earn promotions, the initial sense of adventure quickly decays into the grim, terrifying reality of life inside the crater.
The Fate of Tika and the Tragedy of Descent
Unlike Riko's journey, which is sustained by Reg's immense physical power and relic abilities, your custom protagonist and their peers are normal humans. This distinction highlights the brutal fatality rate of Cave Raiders.
As the plot progresses, your rival and closest companion, Tika, becomes increasingly obsessed with pushing deeper into the Abyss to prove his worth and find a purpose. Driven by ambition and recklessness, Tika ignores warnings and delves far past his authorized whistle rank. His obsession leads to catastrophic consequences.
During high-stakes expeditions into the lower layers, the dark realities of the Abyss catch up to your group. Tika suffers devastating injuries and becomes a victim of both ferocious native fauna and the inescapable Curse of the Abyss—the physiological strain experienced when ascending from the depths. The story doesn't shy away from tragedy; your protagonist is forced to watch their friends suffer horrific injuries, mental breakdowns, or grotesque mutations, reinforcing the core theme that the Abyss claims almost everyone who seeks its secrets.
Encounters with Legendary White Whistles
As your custom character reaches Black Whistle status and descends into the Fourth and Fifth layers, the narrative intersects with major figures from the original series lore:
- Ozen the Unmovable: Stationed at the Seeker Camp in the Second Layer, Ozen serves as a harsh reality check. She tests the protagonist's resolve through brutal physical combat, forcing them to understand that passion alone will not keep them alive in the depths.
- Bondrewd the Novel: The terrifying White Whistle known as the Sovereign of Dawn governs Ido Front in the Fifth Layer. In the game's final acts, your protagonist travels to Ido Front, where Bondrewd's twisted scientific experiments and morally bankrupt philosophies on progress and force-field research are put on full display.
- Nanachi: Players also encounter the beloved Hollow, Nanachi, in the Fourth Layer, offering crucial assistance and emotional depth during the campaign's darkest moments.
The Curse of the Abyss and Core Themes
The narrative of Made in Abyss: Binary Star Falling into Darkness relies heavily on the physical and psychological mechanics of the Abyss's curse. The strains of ascent vary depending on depth:
- 1st Layer: Light nausea and dizziness.
- 2nd Layer: Intense nausea, headaches, and numbness in limbs.
- 3rd Layer: Vertigo combined with visual and auditory hallucinations.
- 4th Layer: Intense body pain and bleeding from every orifice.
- 5th Layer: Complete sensory deprivation, confusion, and self-harming behavior.
- 6th Layer: Loss of humanity or death.
The overarching story theme is the psychological phenomenon known as the "Abyss Stare" or the irresistibility of the unknown. Despite knowing that the journey downward is essentially a suicide mission, raiders are drawn by an obsessive, almost spiritual longing. Your character's story serves as a somber illustration of this phenomenon: a testament to human curiosity pushed to its absolute, agonizing limits.
Frequently Asked Questions
Is the story in Deep in Abyss canonical?
The "Deep in Abyss" mode is an original story crafted specifically for the video game. While it is not part of the primary manga or anime canon, it was created with input and oversight from series creator Akihito Tsukushi, ensuring that its lore, world-building, and character interactions align perfectly with the established universe.
Do you get to play as Riko and Reg throughout the whole game?
No. Riko and Reg are only playable during the shorter tutorial mode, "Hello Abyss." The vast majority of the game's content and the main story take place in "Deep in Abyss," where you control your own custom-created Cave Raider.
Does the game's story reach the 6th Layer?
The main narrative of Made in Abyss: Binary Star Falling into Darkness extends through the Fifth Layer (Sea of Corpses) and Ido Front. Because crossing into the Sixth Layer represents the "Absolute Last Dive" (a point of no return where human ascension without loss of humanity becomes impossible), the playable story concludes around the Fifth Layer to maintain open-world exploration gameplay.
Final Thoughts
By splitting its narrative between a familiar retelling and an original dark campaign, Made in Abyss: Binary Star Falling into Darkness delivers an authentic depiction of Tsukushi's universe. The original story of the custom protagonist and their doomed companions provides a chilling reminder that in the world of the Abyss, few raiders become legends, while most are swallowed whole by the deep.
