Neito Monoma (物もの間ま寧ねい人と, Monoma Neito?), also known as Phantom Thief (ファントムシーフ, Fantomu Shīfu?) | 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 intelligent person. Regardless of how he acts, two of his most prominent traits are him being vocal and deranged.
