SPEC: Birth (2010)

They're both about people with supernatral abilities.

Want more mind boggling series that gets you hooked on the first episode? SPEC is definitely your next drama to watch. If you like Toda in Liar Game, you'll love her in SPEC.

- Buddy Cop drama
- Both Male lead have the same motive of revenge and personality change
- Both shows have similar "aesthetic" and comedic timing (Invisible is a more serious show)
-Spec is more of a Human vs Mutant while Invisible is the usual Police vs Criminal drama

The humor is similar and they are both concerning detectives solving strange mysteries in sometimes strange ways. Also, there are random references to Keizoku SPEC all throughout the Ataru drama (in the background).

-Both are Tsutsumi Yukihiko works. Expect a lot of slapsticks, 60's-90's pop culture reference, amazing score, and unique cinematography.
-Yamegoku is basically Keizoku/SPEC, but without the element of weirdness.
-Both drama feature Kitamura Kazuki as a cop dressed and act like a Yakuza.

Both excellent crime/detective dramas that offer a serious alternative to the usual (k)drama. SPEC is offbeat and has light fantasy elements added.
