Julien Sanchez - Ultimate Cop - Even though he's a great cop, he's actually horrified of dead bodies. He's great at interrogating people, though, and is also very honest. He gets picked on very easily by Norah but doesn't let it get to him. He is also blind in one eye.

I imagine his voice as deep, and can get shaky when nervious/scared.

If I had to describe what I want his voice to sound like based on already existing Danganronpa characters, I would say Gonta (without the 3rd person weird stuff) from danganronpa v3.
