Sakuta's most iconic trait is his consistent deadpan face and manner of speech regardless of his emotional state. He will often voice whatever he has on his mind with a calm demeanor. Sakuta is a socially isolated and calm individual as a result of his ordeal with Adolescence Syndrome. While he states that he is not bothered by what people think about him, or care about trying to fit in and be accepted by his classmates, he does admit that rumors about him are sometimes quite painful to hear. Nonetheless, he states that he doesn't care if the whole world would hate him, as long as one person would need him, and isn't hesitant about defying social norms.Sakuta is also not afraid to show his perverted side and will often make blunt and straightforward lewd remarks to the girls he interacts with. However, these comments are mostly jokes he directs at others and are by no means ill intended.
