Sakuta Azusagawa 梓川 咲太 is the main male protagonist of Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai series.
Sakuta is a young man of average height. He has three claw marks that go across his chest, which are a result of Adolescence Syndrome. At school, he is primarily seen wearing his school uniform. His hair and eyes are brown. At times, his scars open during moments of extreme emotion such as when Kaede experienced her Adolescence Syndrome.
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 is 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 and that his indifference comes from a feeling that it is pointless to try and go against the "atmosphere", the social order of school and tries to hide from it. 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 defining social norms.

Despite his anti-social demeanor, he does show care and compassion for those who he cares about, especially those who suffer from bullying or the Adolescence Syndrome like his sister and himself.

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.

All in all, Sakuta's personality can be summarized as very selfless, nice and helpful, but also very snarky. He's definitely blunt, honest and straightforward towards Mai, and prone to lewd jokes that even intimidate her. Ultimately, they both love to tease each other, and have very similar personalities.
