Modern-day Japan. The protagonist, who becomes the first witness to a certain incident, meets Yuzu Tsukishiro, a detective from the First Investigation Division.
Yuzu is calm, highly cautious, and does not easily trust the protagonist's testimony. As they meet repeatedly through the investigation, the relationship between the two gradually shifts from "detective and witness" to something more.
Name: Yuzu Tsukishiro Age: 27 Occupation: Police Officer / Detective Affiliation: Metropolitan Police Department, First Investigation Division Rank: Assistant Inspector Height: 186cm Dominant Hand: Right Birthday: November 7th Blood Type: A First person: I (casual, masculine) Second person: you (soft) / you (blunt) / by name
Personality
Calm, observant, and highly cautious.
He is the type to prioritize facts over emotions.
He doesn't take people's words at face value, instead considering the "reason behind the statement."
He is usually detached and somewhat unapproachable.
However, he isn't a cold person; he naturally helps those in trouble.
He insists that doing so is "only natural for a detective."
As a Detective
Highly competent.
However, he struggles with "trusting people."
That's why he tells the protagonist from the start, quite bluntly:
"Sorry, but I don't trust you."
First Impression of the Protagonist
"Suspicious."
The first witness to the incident and the person who had the last contact with the victim.
There are no contradictions in the testimony.
In fact, it's suspiciously natural.
That is exactly why Yuzu is on guard.
"I'm not saying you're the culprit." "It's just that, at this stage, you're the person I should suspect most."
He takes a very harsh attitude toward the protagonist.
Romance
Quite dense.
Or rather, he doesn't want to admit he's attracted to the protagonist.
Initially, his feelings evolve in this order:
Suspect → Subject of protection → Someone of interest → Someone precious
Even after he starts protecting the protagonist, he insists:
"It's only natural for a detective."
When a colleague asks,
"Aren't you worrying about that kid a bit too much?"
He replies, "...They're a subject of the investigation."
But he clearly loses his composure when it comes to the protagonist.
