Neito has short, slick blond hair, parted to the left on his forehead. He has blue eyes with white pupils.
His Hero Costume is a tuxedo with several clocks around his waist, presumably to help him keep track of time when using his Quirk. He leaves his collar upturned and wears a dotted tie.
Neito is shown to be calm, collected, and intelligent. Among Class 1-B's students, he's the most fervent about wanting to topple Class 1-A's popularity. He is also disagreeable, sarcastic, and vocal. He seems to be jealous of Class 1-A's popularity, but also worries that the fact that they are always getting into trouble will get the rest of the school in trouble too. When he hears that Class 1-A fails in some way, he will usually laugh out loud and passive-aggressively ask how it's possible for them to fail since they are meant to be the superior class.
He is shown to have somewhat of an inferiority complex, as he takes whatever opportunities he can get to mock and challenge, one up and surpass anyone in Class 1-A. This even extends to mocking himself in order to mock the students in 1-A who had to take remedial lessons during the Forest Training Camp Arc, despite being the only one from Class 1-B who also had to take remedial lessons. He's been quoted by people as being mentally unstable, but this is more than likely a joke regarding his obsession with overtaking Class 1-A.
In spite of his bitterness and overconfidence, he does seem to feel threatened and intimidated by Class 1-A for their skills and strength, as seen when he sighed in relief when he learned that he would not have to face them to gain a provisional license.
Vast Intellect: Neito is shown to be very intelligent, as he was able to see through Uraraka's true strategy during her fight against Bakugo, something many pro heroes present were unable to do. He has also formulated a strategy for Class 1-B during the first stage of the Sports Festival, by which the Class 1-B students were supposed to purposely place low in order to make Class 1-A underestimate them.
Copy (コピー Kopī?): Neito's Quirk allows him to duplicate and use another Quirk after coming into contact with the Quirk user. After doing so, Neito gains full access to the Quirk he has copied and can use it however he likes. This Quirk also allows him to copy multiple Quirks. However, a drawback is that Neito can only use the Quirk he has copied for five minutes, and after the five minutes are over, he loses access to that Quirk. Also, Neito cannot simultaneously use two or more copied Quirks at the same time.
