Arifureta: From Commonplace to World’s Strongest – Season 1 (2019)

The Birth of the Abyss Survivor

Season 1 of Arifureta: From Commonplace to World’s Strongest lays the brutal foundation for one of the darkest isekai transformations in modern anime. What begins as a standard classroom-summoning fantasy rapidly descends into betrayal, isolation, and survival horror, setting this series apart from traditional hero-driven narratives.

This season is not about saving the world — it is about enduring it.

Season 1 introduces the emotional, psychological, and physical breaking point that forges Hajime Nagumo into the feared figure he becomes in Season 2 and Season 3.

Story Summary

Hajime Nagumo is summoned to another world along with his entire high school class, tasked with serving as heroes to protect humanity. While his classmates receive powerful combat-oriented abilities, Hajime is given the Synergist class — a crafting role considered weak and useless in battle.

Mocked, ignored, and sidelined, Hajime struggles to survive even basic missions.

During an expedition into the Great Orcus Labyrinth, disaster strikes. Betrayed by a classmate, Hajime is sent plummeting into the deepest abyss of the dungeon — a place believed to be certain death.

There, surrounded by powerful monsters and poisoned terrain, Hajime is forced into a nightmare of constant combat. Injured, starving, and mentally broken, he makes the desperate decision to consume monster flesh to survive — an act that nearly kills him but permanently alters his body.

Through relentless trial, Hajime abandons his former ideals. Compassion gives way to pragmatism. Mercy is replaced by efficiency.

In the depths of the labyrinth, Hajime meets Yue, an ancient vampire sealed away for centuries. Their partnership becomes the emotional core of the season, blending trust, devotion, and mutual survival.

By the time Hajime escapes the abyss, he is no longer a victim — he is a predator.

Season 1 concludes with Hajime stepping back into the world, armed with overwhelming power, advanced weaponry, and a single goal: return home, regardless of who stands in his way.

This transformation sets the stage for the reunions, divine conflicts, and world-scale consequences explored in Season 2 and Season 3.


Major Arcs Covered

  • Class Summoning Arc — Introduction to the world, classes, and betrayal.
  • Great Orcus Labyrinth Arc — Survival, transformation, and rebirth.
  • Vampire Sealing Arc — Yue’s introduction and emotional bonding.
  • Labyrinth Escape Arc — Hajime’s emergence as a new existence.


Main Characters (Season Focus)

  • Hajime Nagumo — A former ordinary student reborn as a ruthless survivor. His transformation defines the entire series.
  • Yue — An immortal vampire whose calm intelligence and devotion anchor Hajime’s fractured humanity.
  • Shea Haulia — Introduced late in the season, a rabbitkin warrior whose strength and optimism contrast Hajime’s cold resolve.
  • Kaori Shirasaki — Hajime’s former classmate whose concern for him persists even after his disappearance.


Themes & Tone

  • Betrayal & Isolation — Trust shatters instantly.
  • Survival Over Morality — Idealism dies in the abyss.
  • Transformation Through Pain — Power is earned through suffering.
  • Anti-Hero Genesis — Hajime rejects the role of “hero”.
  • Love as Stability — Yue prevents total emotional collapse.

Season 1 carries a grim, survival-horror tone with moments of quiet intimacy that soften its brutality.


Animation & Music

Season 1’s production faced challenges, particularly with inconsistent CGI during monster battles. While this drew criticism, the emotional weight of Hajime’s transformation and the series’ atmosphere remained impactful.

The opening theme “FLARE” became strongly associated with Hajime’s rebirth, while the ending theme emphasizes loss, reflection, and resolve.

Later seasons show noticeable improvements in visual consistency and action pacing.

Popularity & Reception

Season 1 received mixed critical reception due to animation quality, but it gained a strong fan following for its bold storytelling, dark tone, and unique protagonist.

Many fans credit Season 1 as the emotional backbone of the entire series, as Hajime’s abyss experience shapes every decision he makes in Season 2’s reunions and Season 3’s god-level confrontations.

Despite its flaws, Season 1 remains one of the most talked-about “betrayal arcs” in isekai anime.


Final Thoughts

Season 1 of Arifureta is not comfortable viewing — and that is its strength. It strips away fantasy wish-fulfillment and replaces it with pain, endurance, and transformation.

This is the season where Hajime Nagumo dies —
and the strongest survivor is born.

For viewers continuing into later seasons, everything that follows is built upon the suffering endured here.
