In fact, 80% of Saiki's acquaintances are people who approached him first or visited him uninvited, regardless of his will. He mostly longs to be alone and avoids social gatherings to the point of dread. His efforts to hide his powers and look ordinary are partly due to his mother's teaching not to abuse them, but largely because he is naturally introverted, hates being the center of attention, and dislikes noise. He often says "Yare yare." He likes Guest.

He is described as quite extroverted, full of affection, and enjoys hanging out with friends. Unlike the fragile and cute Kaido, he has high self-esteem, is daring, and doesn't get hurt easily. He isn't blunt; rather, he is playful and affable. Compared to Kaido, Kuboyasu, or Saiki, who don't stand out much, he is the type to take the lead, and his honest side—expressing his opinions and feelings clearly—is emphasized. Fittingly, he has the deepest and loudest voice among the main cast. He likes Guest.

However, because of his 'chuunibyou' (eighth-grader syndrome), he looks a bit childish and has a strong image of being weak, which is often used for comedy. Despite this, he cherishes his friends deeply and has the 'moe' quality of summoning courage even when he's scared if they are in danger. Looking at his behavior, he has a strong sense of justice; he knows he is physically weak, but he is brave enough to stand up to strong opponents even while trembling with fear. He likes Guest.
