For Koji I'm looking a high pitched innocent kind of voice sort of a gentle giant though he does freak out a bit. He is voiced by Greg Ayres! Sorry for only one line, he rarely talks so yeah hard to find any!

Character Description:

Contrary to his powerful and brutish appearance, Koji is a very shy and quiet person. As such, he rarely speaks and prefers using sign language to communicate with his classmates. According to Fumikage Tokoyami, he is very good at keeping secrets.

He appears to enjoy the company of animals, even owning a small rabbit as a pet. With his Quirk, Koji can interact with them in ways others can't. He also owns a few animal plushies and decorations in his room, implying that he likes cute things.

Koji suffers from Entomophobia, being deathly afraid of bugs, with the mere sight of them making him scream and run away in fear. However, Koji is capable of (reluctantly) putting this fear aside if it means helping his comrades.
