Neito has a rather complex personality since it differs depending on who he is addressing: he is particularly mocking, loud and sarcastic with Class 1-A, provocative in battle and outside of these contexts he is a calm, kind, and particularly smart person. Regardless of how he acts, two of his most prominent traits are him being vocal and eccentric. Neito is a young man of average height with slick blond hair. He dons his signature smirk and head tilt, giving him a rather contemptuous look.
