Tsukumo Ryusuke is a quirky, yet brilliant neuroscientist working for the National Research Institute of Police Science. Wielding a unique perspective and psychology, Tsukumo tackles the nation's most baffling crimes and scandals, going head-to-head with the most brilliant and twisted criminal minds. But his eccentricities and poor social timing can also aggravate people and circumstances, further complicating matters.

This show provides examples of:

  • Accidental Misnaming: Detective Hayashida is frequently called "Rinda" by Tsukumo.
  • Amateur Sleuth: Tsukumo, who tends to get chastised by his boss for not concentrating on his "research".
  • Ax-Crazy: Kanako in her "Shunsuke" persona.
  • Batman Gambit:
    • Tsukumo relies on the culprits' "natural reflexes" (caused by their brains) to expose them.
    • The culprit's schemes in the last two episodes.
  • Big Eater: Kanako in her "Shouko" persona.
  • Bunny-Ears Lawyer: Tsukumo, a brilliant and eccentric neuroscientist.
  • Butt-Monkey: Kazune.
  • Catchphrase: "My name is Tsukumo, written as 9-10-9 in kanji numerals."
  • Chaste Hero: Due to partial brain damage caused by an accident, Tsukumo is totally clueless about Kazune's advances on him, and keeps wondering why he's in possession of a porn magazine in the first place.
  • Everyone Calls Him "Barkeep": The cleaning lady.
  • Exactly What It Says on the Tin: The show has some very specific episode titles, including:
    • "Eccentric Neuroscientist vs. Beautiful Revived Ghost!!"
    • "Invisible Man Setting Up Serial Murders!!"
    • "Eccentric Neuroscientist vs. Beautiful Woman With A Split Personality!!"
  • Expy: Takegami is a manipulative cannibalistic murderer like Hannibal Lecter.
  • I'm a Humanitarian: In the second episode, GACKT's ham-tastic character Takegami Teijirou is a cannibalistic serial killer who considers eating human flesh to be the equivalent of eating beef or pork.
  • Insufferable Genius: Even though Tsukumo Ryusuke usually figures out the crimes long before anybody else, he is still considered insufferable by many of his superiors.
  • Giggling Villain: Takegami Teijirou.
  • Kids Are Cruel: Kanako's classmates ridiculed her request for accompanying her home, resulting in her kidnapping.
  • Large Ham: It's obvious GACKT is having a lot of fun playing a cannibal.
  • No Social Skills: Part of the reasons why many other scientists dislike Tsukumo.
  • Not My Driver: Happens to a victim in Episode 7.
  • Obviously Evil: Takei, who's bald and is frequently seen with a smug smile on his face. He's actually a case of double subversion of this trope.
  • Posthumous Character: Takegami Teijirou.
