【2025 Update】Are Kansuke Yamato and Yui Uehara Dating?

Detective Conan is famous for canon pairings—Shinichi & Ran, Heiji & Kazuha, Takagi & Sato—so there’s still every chance that Yamato and Uehara will get together later on. Keep watching!
Yui’s First Appearance Was as “Yui Torada,” Already a Married Woman
Kansuke Yamato and Yui Uehara debuted in the “Fūrinkazan” storyline.
Viewers who know their current status may be shocked to learn that Yui’s surname on her first appearance is “Yui Torada.”
At that point she was married to Yoshiro Torada of the Torada family.
The “Fūrinkazan” case is collected in Volume 59 of the manga.
Yui Uehara Never Loved Yoshiro Torada
Yui married Yoshiro Torada without any romantic feelings.
Her real motive was to infiltrate the Torada household—deeply linked to the six-year-old case of Officer Kai’s death—and gather evidence.
Originally Yamato and Uehara had investigated the case together, but when Yamato disappeared for more than ten months, Yui entered the marriage so she could solve it alone.
After “Fūrinkazan,” Yui Joins Nagano Prefecture’s First Investigation Division
Once the “Fūrinkazan” arc ended, Yui’s undercover objective was complete.
Her husband Yoshiro Torada was already deceased, leaving Yui no reason to remain with the family.
At that moment, Kansuke Yamato told her:
Kansuke Yamato: 「Idiot! Didn’t you hear me? Join the police. When you’ve shaken off those ties and settled down, come back! The superintendent’s waiting…for your terrible coffee.」
From her next appearance onward, she is no longer Yui Torada but Yui Uehara, reinstated in the Nagano Prefectural Police First Investigation Division.
Yui Uehara Has Loved Kansuke Yamato Since Childhood
During the Fūrinkazan case, Yui Uehara advises Kazuha—who has a crush on Heiji—by saying:
“Swift as the wind… Acting while your feelings are still burning is one strategy.
If you dawdle, the one you love may disappear before you can speak—and then it’s too late.”
Yui’s words reveal her own regret: six months earlier, Kansuke Yamato vanished before she could confess. Her feelings become even clearer when Yamato casually calls her “missus!”:
“So you won’t call me by my name anymore… Kan-chan?”
Yui’s Crush Began in 1st Grade…
In Volume 107, Yui recalls an elementary-school sports day. A heroic sixth-grader Kansuke impressed her so much that Haibara teases:
Haibara: “Ah, so that’s when you fell for him… ”
Ayumi: “Wait—which one did she fall for?”
Haibara: Kan-chan♡”
At that moment, first-grader Yui realized her feelings for the older sixth-grader Kansuke—a childhood crush that still endures.
Does Kansuke Yamato Love Yui Uehara Too? Are They Both in Love?
Yui’s side is obvious, but what about Yamato? Evidence suggests the feeling is mutual.
“The Darkness of the Prefectural Police” Arc Hints at Mutual Love
Near the end of this arc, the pair share a revealing exchange:
Yui: “Fine, I won’t worry about you anymore! I’m sure a divorcée is the last person you’d want fussing over you…”
Yamato: “Idiot… I’ve got my own ‘scarlet letter’—this huge woodpecker scar on my face. So don’t let yours bother you.”
Yamato blushes as he speaks, gently reassuring Yui that her divorce doesn’t matter to him—classic Kansuke Yamato tenderness that points to shared affection.
