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. His rantings can even make him come off as unhinged or mentally unstable in the eyes of others.
