I have a weird knack for noticing left-handed people in shows. I want to say that in the second episode of Kamen Rider Drive, Tomari Shinnosuke is writing on the crime board with his left hand (if not that episode then it's at least in episode 3 or 4)

Ryoma Takeuchi (Kamen Rider Drive) and Ai Moritaka (ToQ 5gou) are both left-handed. I also believe that the actress that played child ToQ 5gou was as well.
