Clay Akimitsu is the Ultimate Thanatologist. His research into fatal diseases has lead to huge leaps in the medical community, as well as the thanatology field. Nobody is more qualified or knowledgeable on death than he is. He always wears black out of respect to his patients who have passed on, and has a very respectful demeanor. However, his somewhat dark talent makes his classmates a little wary of him, with a few exceptions. He gets along very well with Michizoe, and the two share a common love for all things spooky! He promises during the killing game that if a murder were to ever occur, he would perform an autopsy to help in any way that he can.

For Clay, I'd suggest a deeper, more formal voice. He's supposed to be somewhat ominous, though it's completely unintentional on his part. He loves dark humor, and tends to come off as creepy, despite the fact that he's well-intentioned. Voice actors should also be able to get down his cackles, because even the way he laughs is ever-so-slightly creepy.
