I have been captivated by Psychic Detective Yakumo (known in Japan as 心霊探偵八雲) ever since I discovered the anime years ago. But as I dug deeper, I realized there is far more to the story—especially in the novels—than what made it to the screen.
In this article, I want to share a spoiler-packed exploration of the Psychic Detective Yakumo plot and ending, referencing exact volumes for clarity. My motivation for writing this is simple: I’ve waited nearly two decades to see how the series concludes, and I’m thrilled to finally offer an in-depth look at this beloved work.
Spoiler Warning – The following article discusses plot details and key elements of the anime.
Character Background and Red-Eyed Mystery
At the center of Psychic Detective Yakumo is Yakumo Saito, a college student born with a crimson left eye—a trait that enables him to see wandering spirits. From the beginning (Volume 1, Chapter 1), we see how his unique ability isolates him from others. His early interactions with Haruka Ozawa, a fellow student with a compassionate heart, lay the series’ emotional groundwork.
Despite being offbeat and sarcastic, Yakumo gradually forms relationships that shift his worldview. These bonds—particularly with Haruka, policeman Gotou, and Yakumo’s ever-loyal acquaintances—become crucial in unraveling the mysteries behind each paranormal incident.
Comprehensive Look at Key Volumes
Vol. 1: The Start of Haruka and Yakumo’s Partnership
In Volume 1, Haruka seeks Yakumo’s help when her friend is mysteriously possessed by a spirit after exploring an abandoned school building. Their investigation, which hinges on Yakumo’s spectral vision, foreshadows the partnership they eventually forge. Haruka’s empathy and Yakumo’s harsh but keen mindset present a tension that evolves as they handle more arcane cases involving vengeful ghosts and hidden family secrets.
Vol. 5: Uncovering Mother’s Whereabouts
By Volume 5, the Psychic Detective Yakumo plot intensifies: Yakumo begins to learn more about his mother, Azusa, whose disappearance left him riddled with questions. Haruka’s unwavering support shines through as they uncover the dark circumstances surrounding Azusa’s life and her link to the dreaded “man with two red eyes.” This villain, revealed to be a family member, orchestrates violent schemes from the shadows, forcing Yakumo to confront truths that upend everything he believed about his own origins.
Key Developments in Volume 5:
- Evidence emerges tying Azusa’s whereabouts to old homicide cases.
- Yakumo’s father figure, the two-red-eyed man, manipulates events from behind the scenes.
- Haruka faces mortal danger, underscoring her resolve to protect Yakumo from his own self-destructive tendencies.
Vol. 7 and Vol. 8: The Man with Two Red Eyes
Volumes 7 and 8 pull Yakumo deeper into the labyrinth of his bloodline. The antagonist with both eyes red—Yakumo’s biological father, known as Saito Unkai—causes more turmoil. Early in Volume 7, we learn about Yakumo’s grandmother, whose tragic death played a significant role in shaping Unkai’s warped worldview. By Volume 8, revelations about forbidden family ties emerge, revealing that Yakumo’s mother and Unkai are half-siblings, adding a disturbing layer to Yakumo’s heritage.
Key Revelations:
- Yakumo’s paternal lineage is fraught with scandal and abuse.
- The “two red eyes” ability can be passed down or manifest, fueling supernatural unrest.
- Gotou’s unflagging loyalty leads him to risk his career to protect Yakumo from wrongful charges.
Relationships: From Haruka’s Devotion to Gotou’s Dedication
- Haruka Ozawa: Over the volumes, she stands by Yakumo despite constant brushes with death. Volume 7 showcases her guilt over losing her twin sister in a childhood accident, echoing how she refuses to let Yakumo face his fate alone.
- Gotou Kazutoshi: A detective who has known Yakumo since the boy’s childhood. In early arcs (Volume 2), Gotou recruits Yakumo for bizarre, unexplained crimes. Later, in Volume 8, Gotou is stripped of his official position for helping Yakumo evade custody—an act that cements their father-son-like bond.
- Ishii Yuutarou and the Police Force: Ishii, often comedic relief, matures remarkably across the series, stepping up in Volume 8 and beyond to protect Yakumo from false accusations.
- Aunt vs. Mother Figures: Uncle Isshin was a crucial caretaker but meets a tragic end (Volume 6), leaving a huge emotional void for Yakumo and younger characters who looked up to Isshin’s kindness.
Vol. 13: The Long-Awaited Conclusion
After nearly two decades, Volume 13 finally arrived, tying up the Psychic Detective Yakumo plot and ending in a tense supernatural showdown. In the finale, the father with two red eyes attempts a final gambit: possessing Yakumo, hoping to merge their spirits. Meanwhile, Haruka lies gravely injured, having been kidnapped by a vengeful enemy.
Highlights of the Final Volume (Volume 13)
- Yakumo is forced to choose between sacrificing himself or saving Haruka’s life—mirroring events from earlier volumes but with higher stakes.
- The lines between living and dead blur; Yakumo’s gift becomes both a curse and a saving grace.
- A confrontation “at the beginning’s place” (a key location harkening back to Volume 1) becomes symbolic of Yakumo’s acceptance of both the darkness and light in his lineage.
The series culminates in redemption instead of ruin. Yakumo survives, having overcome his father’s destructive will. Haruka awakens, reaffirming the powerful emotional bond they share. While the path there is strewn with tragedy, the resolution emphasizes hope, acceptance, and a new life for Yakumo—freed from the weight of his inherited curse.
FINAL THOUGHT
I’ve always felt that Psychic Detective Yakumo delivered more than just supernatural thrills. Reading the novels gave me an even richer appreciation for Yakumo’s emotional growth—especially how he warms up to Haruka, who never stops believing in him. The final confrontation made me anxious to the point that I worried I’d see a tragic ending. But discovering the actual resolution, where Yakumo chooses life and connection over despair, felt deeply rewarding.
All in all, Psychic Detective Yakumo’s plot and ending go far beyond the anime’s scope by delving into volumes packed with heartbreak, hidden family ties, and unwavering friendship. After reading through to Volume 13, I can say with relief that the series finishes with a sense of closure: Yakumo overcomes his inner darkness, and Haruka remains the unwavering anchor he so desperately needed.
I hope this deep dive encourages you to pick up the novels for the full experience—everything from the early “haunted school” mysteries to the life-altering final battle is worth savoring. If you’re eager to continue the story right after the anime, it’s best to start from Volume 7. However, because the anime added quite a few changes and original elements, I strongly recommend beginning with Volume 1 if you want the most authentic experience.
