Saku’s Japanese voice is soft, light, and slightly androgynous, sitting in a higher register than most male characters. His tone is calm and reserved, with a quiet, almost delicate delivery that makes him sound introspective and emotionally restrained. He speaks gently, rarely raising his voice, and often sounds thoughtful—as if he carefully chooses his words. There’s a subtle breathiness that adds a sense of vulnerability, giving the impression of someone sensitive but composed. Despite the softness, there’s still a faint underlying firmness that reminds you he’s not weak—just quiet and observant.
