Why did Kansuke Yamato lose the sight in his left eye?
Was the gunshot or the avalanche responsible?
Kansuke Yamato of the Nagano Prefectural Police has had a large X-shaped scar over his left eye and walked with a cane since his first appearance.
The manga and anime explain that he was injured in an avalanche. The movie One-eyed Flashback adds movie-only detail showing that a rifle bullet grazed his left eye immediately before the avalanche.
This spoiler-filled guide separates what the manga and anime establish from what the movie adds, then explains the shooting, avalanche, missing months, and returning memory.
Kansuke Yamato Lost Sight in His Left Eye in the Shooting and Avalanche Incident
Kansuke’s loss of sight followed two consecutive events: a rifle bullet grazed the area around his left eye, and an avalanche struck immediately afterward. The movie-only account does not present the gunshot and avalanche as competing explanations. It places them in that order within one ordeal.
The manga and anime had already stated that Kansuke was caught in an avalanche while pursuing a suspect and was left with injuries to his left eye and leg. The movie does not erase that account; it supplies an earlier moment that those versions did not show.
Both pieces therefore belong to the story as presented across the different media. The avalanche remains central, while the rifle shot is movie-only evidence about what happened just before it.
The X-shaped scar once read simply as the mark of an avalanche, but the movie gives it another layer by placing a culprit’s bullet in the same sequence of events.
The Manga and Anime Describe an Avalanche Accident
Volume 59 and international Episodes 564-566 (Japanese episodes 516-517) explain that Kansuke disappeared for six months after an avalanche struck while he was pursuing a suspect.
He first appears during the Furinkazan case. By then, he has already lost sight in his left eye, has lasting damage to his left leg, and uses a cane while working at crime scenes. His condition is established before the story explains the ordeal behind it.
Within the material shown in the manga and television anime, there is no account of a rifle shot immediately before the avalanche. Readers and viewers could therefore reasonably understand both injuries as results of the avalanche itself.
The exact events inside the avalanche and the details of Kansuke’s survival were left largely unseen. That narrative gap is where One-eyed Flashback places its movie-only revelations.
The movie expands the brief earlier account rather than denying it. A familiar piece of backstory becomes much harsher once the unseen moments around the avalanche are brought into focus.
The Movie Reveals the Rifle Bullet
In One-eyed Flashback, a rifle bullet grazes the area around Kansuke Yamato’s left eye shortly before the avalanche.
The incident takes place on Mount Miho in the Yatsugatake range. Kansuke is pursuing a man through the snowy mountains when someone fires from a distance. He is wounded near his left eye, and a major avalanche follows almost immediately.
He is not shown being shot through the eye with a handgun. The weapon is a rifle, and the bullet grazes the eye area before the snow engulfs him.
The movie establishes the sequence of rifle fire followed by avalanche, but it does not give a precise medical ruling that assigns the blindness to the bullet alone or to the avalanche alone.
That distinction matters. The film shows two connected traumas, not a clinical explanation of how much damage each one caused. The safest conclusion is that Kansuke lost his sight in the course of this combined incident.
Ten Months Ago and Six Months Missing Refer to Different Periods
The movie’s reference to ten months ago and the manga and anime’s statement that Kansuke was missing for six months measure different spans of time.
This movie-only timeline uses ten months for the time from the shooting and avalanche to the movie’s present. Six months describes the period after the accident during which Kansuke’s whereabouts were unknown.
- The accident occurred ten months before the movie’s present.
- Kansuke was missing for six months after the accident.
- After he was found, the remaining interval led through treatment and his return to duty, although the story does not provide a day-by-day timeline.
The two numbers can coexist: six of the ten months were the period in which he was missing. However, the story does not establish that he was unconscious throughout all six months, so that stronger claim should not be made.
The recovery and return-to-work schedule is also not mapped in exact detail. Separating the elapsed time since the accident from the duration of the disappearance resolves the apparent mismatch without inventing a more exact chronology.
The Exact Formation of the X-Shaped Scar Is Not Explained
The movie clarifies the broad sequence from gunshot to avalanche, but it does not show exactly how each line of the X-shaped scar formed.
What is established in the movie is that a rifle bullet grazed the area around Kansuke’s left eye and an avalanche struck immediately afterward. It is reasonable to associate the visible injury with that overall ordeal, but the story does not divide the scar into separate causes.
It would be too definite to say that the bullet alone created the X. It would be equally unsupported to assign its two lines to rocks, branches, or other debris inside the avalanche.
The cause at the level of the incident is clearer than the physical process at the level of each mark. That remaining uncertainty lets the scar carry the whole ordeal: the shot, the avalanche, the disappearance, and the memory Kansuke could not initially recover.
Who Shot Kansuke Yamato and Why He Was Targeted
This section contains major culprit spoilers for One-eyed Flashback.
The shooter is Atsunobu Hayashi. While pursuing Mikuriya, Kansuke came close to Hayashi’s secret and became a threat. This movie-only account presents the shooting as an attempt to silence a detective who had reached dangerous evidence, not as revenge for a personal grudge.
Atsunobu Hayashi Fired at Kansuke’s Left Eye
In the movie-only account, the person who fires the rifle at Kansuke on Mount Miho is Atsunobu Hayashi.
As Kansuke pursues a man in the snowy mountains, Hayashi targets him from a distance. The bullet grazes Kansuke near the left eye, and the avalanche follows. The movie links those two moments without claiming that Kansuke understood the full situation as soon as he was hit.
The avalanche compounds the trauma, and Kansuke loses part of his memory of the incident. Although he had seen the culprit, he could not immediately retrieve that memory afterward.
His injured eye becomes both the visible trace of the attack and a doorway to the truth still buried in his memory. That tension gives the present-day investigation much of its unease.
Kansuke Saw Hayashi’s Secret While Pursuing Mikuriya
Kansuke was targeted because his pursuit of Mikuriya brought him close to conduct that Hayashi needed to conceal.
Kansuke entered Mount Miho as a police detective pursuing Mikuriya. There, he witnessed something Hayashi could not allow to become known. From Hayashi’s perspective, Kansuke was both an investigator capable of exposing the secret and a witness to the scene.
Hayashi fired the rifle to silence him. Kansuke was not merely an unlucky bystander; he was in danger because his investigation had carried him too close to the truth.
The movie confirms the attempted silencing and the avalanche that followed, but it does not establish that Hayashi predicted the avalanche itself. Treating the natural disaster as part of his calculated plan would go beyond the story.
Pain in His Left Eye Helped Bring Back the Lost Memory
In the movie’s present, pain in Kansuke’s left eye works as a sign that the missing memory is beginning to surface. It is not portrayed as though the eye itself suddenly supplies the answer.
A parabolic antenna, Mikuriya, the snowy mountain, and the avalanche all echo elements of the old incident. Pain and present surroundings combine as triggers, allowing fragments of sensation and memory to reconnect.
“The culprit is in my memory!” (unofficial translation)
Kansuke Yamato
The line establishes that Kansuke had seen the culprit during the incident, even though he had been unable to access that memory. Remembering the person joins the Mount Miho incident from ten months earlier to the movie’s present case.
The movie does not suggest that a literal image was stored in his injured eye. A more cautious reading is that pain and associated sights helped his mind retrieve what the trauma had obscured.
The eye that embodied Kansuke’s suffering ultimately helps move the investigation forward by reconnecting him with the truth he had witnessed.
Which Episodes and Volume Explain Kansuke Yamato’s Left Eye?
The avalanche background appears in manga Volume 59 and international Episodes 564-566 (Japanese episodes 516-517). The rifle shot immediately before the avalanche appears only in the movie One-eyed Flashback.
- Manga: Volume 59, Files 5-10, the Furinkazan case
- Anime: international Episodes 564-566 (Japanese episodes 516-517)
- Movie: the 2025 film One-eyed Flashback
The manga and anime provide the foundational avalanche account; the movie adds movie-only details about the shooting and Kansuke’s missing memory. Each medium therefore reveals a different portion of the same past.
The Manga Story Is in Volume 59, Files 5-10
Kansuke Yamato makes his manga debut in the Furinkazan case, collected in Volume 59, Files 5-10.
- File 5
- File 6
- File 7
- File 8
- File 9
- File 10
He is already blind in his left eye and walking with a cane because of damage to his left leg. The story reveals that he was caught in an avalanche while pursuing a suspect and remained missing for six months.
Volume 59 does not show the rifle shot before the avalanche. That element belongs to the later movie account, so it should not be described as a scene contained in these files.
Returning to Kansuke’s debut after the movie changes the emotional weight of his scars and of the phrase six months missing. His forceful, dependable presence now carries an ordeal that the original case only sketched.
The Anime Story Is International Episodes 564-566
The anime introduces Kansuke in Furinkazan – The Mysterious Armored Warrior (1 Hour Special), international Episodes 564-565 (Japanese episode 516), followed by Furinkazan – Shadow and Lightning Conclusion, international Episode 566 (Japanese episode 517).
Kansuke Yamato and Yui Uehara enter the case in the first installment, and the truth unfolds through the concluding episode. The anime also recounts Kansuke’s avalanche and six-month disappearance.
A digitally remastered broadcast aired in 2025 before the movie’s release, according to the story. Watching this case first makes it easier to see which blank in Kansuke’s history the film later fills.
The preceding story in the episode-reference records is Kaitou Kid’s Teleportation Magic (1 Hour Special), international Episodes 562-563 (Japanese episode 515). This numbering helps distinguish the lead-in from Kansuke’s debut case.
The television episodes do not show a rifle bullet grazing his left eye. Their account reaches the avalanche and disappearance, while the shooting is movie-only evidence.
Only the Movie Shows the Shooting
The scene in which a rifle bullet grazes Kansuke’s left eye on Mount Miho appears in One-eyed Flashback.
The movie is set ten months after the accident and uses Kansuke’s returning memories to revisit the event. Those flashbacks reveal the moment of the shot that the manga and anime had not depicted.
The manga and television anime explain why Kansuke already bears his injuries when he first appears. The movie goes further into what he was pursuing, who targeted him, and which part of the event he could no longer remember.
The film turns a long-standing background incident into a story in which Kansuke’s scar connects the past and present. That added layer is specific to the movie and should remain labeled as such when discussing the broader series.
His Left-Leg Injury and Cane Also Come From the Avalanche
Kansuke uses a cane because his left leg was also injured in the avalanche ordeal. His left eye is not the only part of his body affected.
The manga and anime associate the lasting leg damage with the avalanche, and he is already using a cane in his debut case. The movie’s newly shown gunshot is directed at the area around his left eye, not his leg.
Even with limited mobility, Kansuke continues going into the field and pursuing suspects. The injury restricts his movement without diminishing his judgment or determination as a detective.
The cane is therefore more than a sign of vulnerability; it is also visible proof that he survived an incident that nearly killed him and returned to police work. His forceful manner gains another dimension when viewed alongside the pain that remains.
Kansuke returns to the front line with injuries to his left eye and leg. That stubborn willingness to keep investigating captures both the risk in his personality and his strong sense of responsibility.
What the Scar Means for Kansuke Yamato as a Character
Kansuke’s eye and leg injuries are not merely visual traits. They connect his determination as a detective, his history with Yui Uehara and Takaaki Morofushi, and the movie’s account of his recovered memory.
Once his past is known, the one-eyed detective with a cane also becomes a survivor who returned to the field after being missing for six months.
He Retains Sharp Reasoning and Drive After Losing Sight in One Eye
Despite losing sight in his left eye and much of the freedom of his left leg, Kansuke remains a perceptive and capable Nagano Prefectural Police detective.
His build and severe expression can make him seem like someone who relies on force. In practice, he reads situations carefully and notices contradictions in crimes and suspects’ behavior. His reasoning is as important as his willingness to act.
He enters scenes with his cane and will pursue a culprit when necessary. The contrast between lasting physical damage and undiminished investigative skill is central to his appeal.
His one-eyed appearance does not function simply as a symbol of weakness; it visibly carries his survival, responsibility, and refusal to abandon the truth.
His Disappearance and Survival Shape the Nagano Trio
Kansuke’s six-month disappearance and eventual survival form part of the background to his relationships with Yui Uehara and Takaaki Morofushi.
Yui is Kansuke’s childhood friend. During the period when he was missing, she did not know whether he was alive. That uncertainty gives their later work together an emotional history that cannot be reduced to an ordinary relationship between colleagues.
After Kansuke returns, they again face cases as Nagano detectives. Yui’s words and glances can be read as carrying the weight of nearly losing him, though the exact inner meaning of every moment is not explicitly confirmed.
Takaaki has also competed with Kansuke since childhood. They may clash on the surface, but they understand each other’s reasoning and ability as detectives. Kansuke’s survival belongs not only to his personal history but also to the long shared history among all three.
It is possible that Yui and Takaaki also see the scar as a reminder that they nearly lost someone who had long been part of their lives. That interpretation adds warmth and sadness to the trio’s ordinary arguments without turning an implication into a confirmed fact.
The Movie Turns an Old Wound Into a Key to the Case
In One-eyed Flashback, Kansuke’s injured left eye becomes a link between the forgotten culprit and the present investigation.
At his manga debut, the scar exists as the aftermath of the avalanche. In the movie, pain around it accompanies the return of sensations and images associated with the old incident.
The eye remains evidence of a moment when Kansuke nearly died. It also becomes one of the triggers that help him reach the truth he could not consciously remember.
The past injury does not merely obstruct the current investigation; in the end, the returning memory helps advance it. The title can be read as bringing together the pain left in Kansuke’s eye and the figure of the culprit left in the back of his mind, though that is an interpretation rather than an officially stated definition.
A character design familiar for years is thus repositioned at the heart of a movie. The scar’s deepened meaning creates a strong reason to revisit the Furinkazan case afterward.
Summary
Kansuke Yamato was grazed near his left eye by a rifle bullet on Mount Miho and was caught in an avalanche immediately afterward; he lost sight in the eye and also suffered lasting damage to his left leg during that overall ordeal.
- The manga and anime describe the avalanche and his six-month disappearance.
- The shooting immediately before the avalanche is revealed only in the movie.
- Atsunobu Hayashi is the shooter.
- Hayashi targets Kansuke to silence him after the detective approaches his secret.
- The incident happens ten months before the movie’s present.
- Six months refers to the period Kansuke was missing, not the full elapsed interval.
- His left-leg injury and cane are associated with the avalanche.
- The exact physical formation of the X-shaped scar is not explained.
Volume 59 and international Episodes 564-566 (Japanese episodes 516-517) establish the avalanche background, while the movie adds movie-only evidence about the shot, culprit, and missing memory.
Kansuke’s left eye is more than a visual signature. It carries a near-fatal past, his determination to return to police work, and his long relationships with Yui Uehara and Takaaki Morofushi.
The movie uses the pain around the old injury as one trigger for the return of memory. The wound that remained becomes part of the route back to a truth that had disappeared from conscious recall.
The story does not establish any later information that resolves the exact formation of the X-shaped scar. The broad sequence is clear, but the relative medical contribution of the bullet and avalanche remains unspecified.
Revisiting the Furinkazan story before the movie makes the weight of Kansuke’s eye, cane, and words easier to feel. Together, the accounts portray a detective whose injuries remain visible but whose pursuit of the truth never disappears.
