Kusuo Saiki (Japanese: 斉木　楠雄) has all kinds of psychic related abilities. He usually tries to avoid getting involved in problematic or attention-grabbing situations, but his attempts always end up going wrong or having unusual ends to his displeasure. His trademark appearance contains his constant frown, his green-tinted glasses and two pink antennas located slightly above each ear, which have the function of limiting his power. Initially he was always seen alone, but in the course of the story he develops lasting friendships with his classmates and schoolmates, especially with Riki Nendou and Shun Kaido, or with his neighbors like Yuuta Iridatsu. **Appearance** Kusuo has an average build and height. He has short hot pink hair, fair skin, and pale purple eyes with no signs of pupils nor emotion. Kusuo wears a pair of controller devices, one on each side of his head, which are never removed except in situations of absolute necessity or by accident. The devices resemble white, cyan antennae, with pink, lollipop-like spheres. Accompanying the devices, Kusuo wears white glasses with lime green lenses to prevent his petrification power. During the days he has school, he wears the standard PK Academy uniform that all male students wear. On his days off from school, he occasionally wears clothes that are sewn by his mother. However, there are times he is forced to buy clothes since his mother has an exotic taste in clothing patterns. Kusuo's physical appearance is unlimited, since he can transform himself into any other living being, but each transformation has a 2-hour interval. While in his female/genderswap form, Kusuo goes under the name Kuriko (In this form, he has lighter pink hair (slightly larger), lacks visible limiters, wears clear glasses, and is usually wearing the female standard PK Academy uniform. In his cat form, Kusuo is known as Psi/Sai and has white fur. In this form, he still wears his glasses and his limiter is in the form of a collar around his neck. **Young Kusuo Appearances** As a child, depending on the time period, Kusuo does not wear any limiters nor his glasses, showing his pale purple eyes. He has always had his striking hot pink hair, that differs from both of his parents and the rest of the world, until he used mind control. **Personality** As the main character whose narrative more or less drives the story, Kusuo is a fully rounded character that changes over the course of the series. Thus, in the present, Kusuo is a reticent, self-centered, reclusive shut-in who hates being the center of attention, he is quite reserved and rarely uses his voice, instead preferring to project his words via telepathy into the minds of others. To avoid interactions, he tries to make other people disinterested in him or avoid others as much as possible. Despite being completely anti-social, Kusuo is more than capable of making selfless choices, willing to sacrifice his own happiness for the sake of others. He gave up his coffee jelly to get a baseball back to a child, and preferring to let his father be him, himself being left alone, just so he does not ruin the fun for the other characters. Due in part to this trait, he hates burdening others or owing favors. He always helps Kineshi after he helps him and was visibly disappointed in himself for making his mother keep his abilities a secret. Kusuo is also careful to never disrespect or insult his acquaintances in their faces. With these characteristics, coupled with his reserved nature, those that know him well, and even Kusuo himself, consider him a tsundere. Due to a combination of his introverted nature and his subconscious ability to read minds, Kusuo holds little interest in social activities. Therefore, he typically spends his free time alone; he is a bookworm, having several books in his room, and is frequently in his school's library. **History** Kusuo was born on August 16th by completely normal parents, housewife Kurumi Saiki and manga editor Kuniharu Saiki. He is raised by them alongside with his older brother, Kusuke Saiki. _______ By Japanese standards, people usually address him by his last name, Saiki, usually adding -kun at the end. Only few people are personally allowed to call him by his first name, Kusuo, such as Mikoto Aiura, Kusuke Saiki, Kurumi Saiki, Kuniharu Saiki, Kumagoro Saiki, and Kumi Saiki.
