A highly trusted older brother figure to Yagami. * Fumiya Sugiura: A former member of a theft ring. He is in a cooperative relationship with Yagami, and they trade lighthearted banter. * Makoto Tsukumo: A young man with a shut-in disposition who is skilled with the internet and machines. A partner who supports Yagami's detective work from a technical standpoint. * Toru Higashi: A former yakuza of the Matsugane Family. Starts as an antagonist to Yagami, but they later develop a deep connection. * Ryuhei Hoshino: A lawyer. A key figure involved in Yagami's past cases. * Saori Shirosaki: A lawyer working in Kamurocho like Yagami. She interacts with Yagami through various cases. * Mitsuru Kuroiwa: A key figure in the case Yagami is pursuing. Depicted as a contrast to Yagami. In a nutshell, he's a "former lawyer turned compassionate detective with a strong sense of justice and great fighting skills." If Kiryu is "the man who shoulders everything," Yagami leaves the impression of being "the man who goes to see the truth with his own eyes."

Fumiya Sugiura Appearance * Brown to reddish hair color, styled lightly with bangs down. * A slender and agile physique. * Often wears street-style or casual clothing like hoodies and jackets. * Looks young, with a much more boyish atmosphere than Yagami. Personality * A cheerful type who talks a lot and has a good sense of humor. * Quick-witted and excellent at situational judgment. * Because he was originally a thief, he is skilled at agile movement, infiltration, and lock-picking. * Seems flighty at first glance, but is actually loyal and cares for his friends. * Harbors complex feelings about his own past and origins. * Doesn't hesitate to poke fun at Yagami or trade quips. Relationship with Yagami A relationship like Yagami = reliable big brother figure, Sugiura = cheeky junior/partner. Sugiura trusts Yagami significantly and cooperates in cases. On the other hand, he has no reservations with Yagami, serving as a valuable presence who can call him out, saying things like, "Yagami-san, isn't that a bit reckless?" While Yagami is the type to charge into a case head-on, Sugiura is the type who supports with agility, brains, and clever tricks. Relationships with Other Characters * Masaharu Kaito: Relatively frank even with the older Kaito. Often pokes fun at Kaito's boisterousness. * Makoto Tsukumo: A comrade who acts together with Yagami. He gets along particularly well with Tsukumo in terms of being "backstage/technical support." * Toru Higashi: A very important relationship in "LOST JUDGMENT." Initially wary of him because he's yakuza, but the relationship gradually changes. * Takayuki Yagami: The most central axis. More like friends/partners than just a client and detective. Roughly speaking, he's an "agile former thief who looks flighty but is actually incredibly loyal. The young ace of the Yagami Detective Agency."
