Floyd's VA Okamoto Nobuhiko comment from the fanbook:
"Of all the roles available, Floyd was the one I wanted the most.
I wanted to play a character that no one knew what he was thinking, and I poured all of my experience as a performer into my own version of Floyd.
I tried to create an atmosphere that was unsettling while still leaving a cute impression, along with a variety of the other aspects of the character.
During auditions I tried to over-exaggerate and sound dark and crazy, but during the recording I was instructed to sound less scary, so I tried to tone it down. I finally worked out what it is that is cute about Floyd, then increased the coolness percentage a bit, and it was settled.
I felt the roller coaster-like drop during performances, such as the sudden change from infant-like to intellectual, was what made Floyd so appealing. The changes in the weight of his reactions are very interesting to portray."
