The anime community is reeling following the release of Mushoku Tensei: Jobless Reincarnation Season 3 Episode 11. Entitled “Turning Point 4,” this pivotal chapter marks the most horrifying shift in the entire series, introducing time travel and uncovering Hitogami’s tragic trap aimed directly at Roxy Migurdia.
Future Rudeus (commonly known as Oldeus) traveled decades back through time for a single mission: to stop Present Rudeus from opening his basement door. Following Hitogami’s innocent-sounding advice would trigger a nightmare timeline that begins with Roxy contracting a fatal disease, ultimately destroying Rudeus’s entire family and ruining his life.
Why Did Future Rudeus (Oldeus) Return to Stop Present Rudeus?

Future Rudeus, commonly referred to by fans as Oldeus, traveled decades back through time for one single purpose: to prevent Present Rudeus from opening the basement door and saving his family from absolute destruction.
In Oldeus’s original timeline, Present Rudeus followed Hitogami’s instructions without question. Opening that basement door triggered a devastating sequence of events that began with Roxy:
- Roxy’s Tragic Infection: Opening the basement exposed the house to a deadly rodent carrying a localized parasite. A pregnant Roxy contracted the disease, leading to her agonizing death and the loss of their unborn child.
- The Downward Spiral: Consumed by insurmountable grief over Roxy’s death, Rudeus sank into severe depression and alcoholism. Hitogami continued manipulating events behind the scenes, leading directly to the execution of Sylphiette during a rebellion in the Asura Kingdom, followed by the death of Eris while shielding Rudeus from danger.
- A Lifetime of Regret: Devastated, alone, and driven entirely by vengeance, Oldeus spent decades researching taboo time-manipulation magic. He sacrificed his lifespan, mana, and health to tear through time, deliver a final warning to his past self, and die in the present era.

Hitogami’s Deceit: What the Human-God Told Rudeus After Three Years
After remaining silent for three years following the events in Begaritt, Hitogami (the Human-God) re-entered Rudeus’s dreams under the guise of a benevolent advisor. We already knew that Chaos Breaker Arc will going to bring lot of Chaos.
Claiming to help Rudeus protect his peaceful household, Hitogami warned him that a simple pest had gotten into the basement and was ruining their stored food supplies. He urged Rudeus to go downstairs immediately and exterminate it.
| Feature | Hitogami’s Stated Claim | The Actual Truth |
| Pest Type | Harmless food-destroying rat | Carrier of fatal Petram Syndrome |
| Intended Target | Food provisions | Roxy Migurdia & unborn child |
| Ultimate Goal | Maintain household peace | Prevent the birth of Orsted’s future ally |
Why Hitogami Wants Roxy Dead
Hitogami possesses foresight into future timelines. He knows that a child born to Rudeus and Roxy is destined to join forces with Dragon God Orsted to permanently seal or defeat Hitogami. Because fate mechanics prevent Hitogami from directly attacking Rudeus or Roxy himself, he used manipulation to ensure Roxy would contract a deadly illness.
In the last episode we got to know why Lady Nanahoshi Coughing Blood and also how Rudeus and other brough the cure to keep her illness away.
Hitogami’s Psychological Manipulation: Exploiting Guilt

Before giving Rudeus the instruction about the basement, Hitogami deliberately broke Rudeus’s mental state. He reminded Rudeus of the tragedy in Begaritt, pushing him to blame himself for Paul’s death and Zenith’s loss of memory.
By overwhelming Rudeus with guilt and grief over his parents, Hitogami ensured that Rudeus would not question his motives. Distracted by his own regret and desperate to protect what was left of his family, Rudeus was primed to follow Hitogami’s advice without suspecting a trap.
What Is Really in the Basement? (Light Novel & Manga Spoilers)
According to the Mushoku Tensei source material, the basement contained a rodent infected with Petram Syndrome, an incurable disease in the Six-Faced World that turns internal organs into stone.
Because pregnant women suffer from compromised magical defenses, exposure to Petram Syndrome is 100% fatal to both mother and child. Hitogami calculated the precise timing so that sending Rudeus downstairs would guarantee Roxy’s exposure.
The Turning Point: What Happens Next for Rudeus
By stopping Present Rudeus right outside the basement door, Oldeus succeeds in breaking Hitogami’s trap and saving Roxy. Before succumbing to the fatal strain of time travel, Oldeus leaves behind his personal journal detailing decades of dark history along with three critical directives:
- Never open or enter the basement.
- Sever all trust in Hitogami.
- Seek an immediate alliance with Dragon God Orsted.
With Oldeus’s intervention, Mushoku Tensei transitions from a slice-of-life fantasy story into a grand conflict against the Human-God, altering Rudeus’s destiny forever.
