Ningen Fushin: Adventurers Who Don’t Believe in Humanity Will Save the World is a Japanese fantasy series about four betrayed, disillusioned adventurers who reluctantly band together and end up becoming unlikely heroes. It began as a light novel and has since received manga and anime adaptations, with the anime streaming internationally on major platforms.

Quick Scoop

  • Japanese title / meaning : The series is commonly known in Japanese as Ningen Fushin no Bōkensha-tachi , often rendered in English as Apparently, Disillusioned Adventurers Will Save the World or Adventurers Who Don’t Believe in Humanity Will Save the World.
  • Mediums :
    • Light novel written by Shinta Fuji, illustrated by Susumu Kuroi.
* Manga adaptation.

* TV anime adaptation that began airing in 2023.
  • Setting : A “Labyrinth City” (also called Terrane in some descriptions) full of adventurers, merchants, nobles, priests, and beastmen, famous for its maze-like structure.

Story premise

  • The core idea centers on four people who have lost faith in humanity after serious betrayal, yet are forced to rely on each other to survive and, eventually, to tackle threats on a much larger scale.
  • Main setup:
    1. Nick, an adventurer, is abruptly kicked out of his party by his mentor and dumped by his girlfriend on top of that.
2. Tiana, a prodigy mage, is sabotaged and jilted by her fiancé, which ruins her reputation and pushes her into gambling.

3. Zem, once a priest, is falsely accused of sexual assault after rejecting a girl’s advances and is cast out of the priesthood.

4. Curran, a half-dragon warrior, has something precious stolen by someone she trusted.

All four happen to sit at the same tavern table, venting their frustration and shouting that they “can’t trust humans,” and end up forming the “Survivors” party precisely because no one else will have them.

Themes and tone

  • Distrust and recovery : The show leans on themes of trauma, cynicism, and slow rebuild of trust; each character’s “humanity problems” are rooted in specific betrayals rather than vague angst.
  • Comedy plus drama : Despite dark backstories (false accusations, professional ruin, theft), the tone mixes serious emotional beats with bar banter, party-building gags, and adventuring hijinks.
  • “Will save the world” angle : The title promises a world‑saving scale, but some viewers have noted that the anime’s on‑screen content leans more on personal growth and local adventures than grand, global heroics, especially early on.

Status and where it’s available

  • The anime adaptation began airing in early 2023, with the first episode titled “Disillusioned Adventurers.”
  • It is available to stream legally on platforms like Crunchyroll under the English title Ningen Fushin: Adventurers Who Don’t Believe in Humanity Will Save the World.
  • The franchise continues to be discussed as a niche but recognizable entry in the “party of broken adults in a fantasy world” subgenre of anime and light novels.
