Kazuhiko, despite being incredibly knowledgeable with everything related to robotics, often comes off to many as naïve with little to no common sense. He's a coward at heart, often being very flighty and agitated in moments of stress. Overall, though, he's very energetic and excitable in nature, and is always willing to talk for hours on end about robotics if you're bored.

Kazuhiko's voice should be of a medium-high pitch, being loud and energetic while also somewhat nasally and raspy. Additionally, due to his tendency to be easily frightened, he should be somewhat jumpy; range is very important for this character, so make sure to give it your all, and expect to yell and be loud!
