Akira, a young detective, uses his Invisibility to investigate a case where the Mona Lisa has been stolen by the villainous Team Z.
Toumei Shounen Tantei Akira (also known among English-speaking fans as Invisible Boy Detective Akira or Invisible Detective Akira) is a 1970 anime pilot episode by Knack Productions. Like with several other of Knack's shows, this is infamous for its weird plot and questionable quality and got attention along with Chargeman Ken!'s memetic popularity.
Toumei Shounen Tantei Akira provides examples of:
- Barbie Doll Anatomy: When the naked, invisible Akira is revealed by the Team Z leader's Eye Beams, he's drawn without nipples or genitals.
- Invisibility: Akira is a detective who can turn invisible under his clothes, including a mask and gloves, which he uses to help him investigate cases.
