Kawasemi Omito, a supremely skilled detective, leads a joint investigation into a serial killing case. Amamiya lends him Toto, whom Kawasemi deems so useless he's invisible. Ron appears at the newest crime scene as a consultant, irritating Kawasemi.
It'll be the pure, naïve fool, 
Detective Isshiki!
!بل الساذج النقّي، المُحقّق إيشيكي
sondern der waschechte
Dummkopf, Herr Isshiki!
¡Lo hará el detective iluso Isshiki!
¡Lo hará el detective inocentón Isshiki!
mais l’officier Isshiki,
le crétin au cœur pur.
Sarà il puro e imbecille detective Isshiki a farlo!
e sim, o inspetor Isshiki,
o mentecapto de coração puro!
А глупый и наивный следователь Иссики!
แต่เป็นสายสืบโทโทมารุ
ที่ซื่อบื้อต่างหาก
