Notes for characters in this page:

 * 2) Since these characters are likely to be key characters in a certain case, Spoilers Ahead.

Jinpei Matsuda
"Voiced by Nobutoshi Canna (JP)"

The character that drives the Backstory of the 17 Million Hostages story arc. Former member of the bomb squad, he was later transferred to the criminal team because of his That One Case-- and it was him who became for Sato.


 * Bi the Way: Maybe, if we take both Hagiwara and Sato in consideration.
 * One Scene Wonder: He appeared in two adjacent story arcs as a Posthumous Character and has negligible influence to the main story. Yet, he is often listed with the recurring characters.
 * One has to take note that he and his former partner Hagiwara is an establish yaoi pairing.
 * Posthumous Character: He was already dead for 3 years when he was first mentioned.
 * Tall Dark and Handsome
 * That One Case

Hiroki Sawada
"Voiced by Ai Orikasa (JP) / Maxey Whitehead (EN)"

From the Non Serial Movie Phantom of Baker Street.


 * Adorably Precocious Child: Subverted, if not Deconstructed. While he is young (10) and bears as much adult responsibility (being a master programmer) as for the norm of this trope, he is portrayed as an angsty character. That does not prevent some fans from portraying him per the norm of this trope, though.
 * Author Avatar: Often suspected to be one towards the movie's writer Hisashi Nozawa, not helped by the fact Nozawa himself about 1.5 years the movie screened.
 * Bishounen: At 10, he's a kid edition, but he does have the looks for it.
 * Child Prodigy:
 * Deus Angst Machina: Consider all tropes surrounding him, and consider his age. Everyone would have reached their Despair Event Horizon.
 * Ill Boy: While this has not been further expounded about, it certainly does not help with his social issues.
 * Improbable Age:
 * Intelligence Equals Isolation: A pretty tear jerking example as this was not because of his failure to connect with others. In the beginning, Japanese schools just ignored his intelligence. Under the wing of Schneider, he got accelerated at an improbable rate--and in effect became.
 * I Just Want to Have Friends
 * Innocent Prodigy: He switches between this and Wise Beyond Their Years.
 * Lonely Rich Kid: While under foster care by Schneider, although the reason is a bit different from the the standard of that trope--Schneider put him in a highly acclerated educational program . Understandably, he was a bit broken for that.
 * Parental Abandonment: His parents separated over his education, and he followed his mother to the US. Not long after that, his mother died.
 * One Scene Wonder
 * One Steve Limit: Averted and then played straight. Hiroki is a very common male name in Japan, and there has been at least two one-timer that has the same name before him. Although, referring to "Hiroki" without any quantification usually refers to him
