"The Ultimates are really gonna need him after this, if he doesn't become a subject, that it. Kazuya Matsui, the Ultimate Occupational Therapist. And we're going to have the best therapist at our disposal."

Kazuya Matsui has a presence of mind, usually able to handle any situation through discussions, and is described to have self-control or just "chill" in general. He's seen to be approaching and reliable for others.

Kazuya has a mid-low voice! He's generally calm and has a soothing voice! We will require additional lines from the auditioner in order to give them the full role!
