saiki kusuo🪼٭★٭˚∘•

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.[5] 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[6] (formerly Kusuko[7]). 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.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.[8]

As of the finale, he no longer wears his limiters or glasses. However, right in the end of the epilogue chapters, he reprises them due to his powers begin to return.

When Kusuo was a child, he was more open to his emotions. Part of it was due to the fact that he was unaware of what his powers did, such as breaking a whack-a-mole machine in an arcade and thinking the machine was giving him praise.[9] He was highly mischievous, such as making his parents look for him for 5 hours after he teleported,[10] and smiled around others without a second thought. However over the course of time, with having to hide his psychic powers from others and his abilities slowly ruining experiences for him, he started to close himself up.

Thus, in the present, Kusuo is a reticent, self-centered, reclusive shut-in who hates being the center of attention,[11] 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. For example, Kusuo hiding from the other characters in the bathroom[12] and Kusuo talking to Imu, knowing Kokomi would not like it
