Despite how he mistreated her, Hannah later admits that she has loved Alois the whole time and his attitude towards her changes completely he accepts her loving him since he can no longer gain any of the acknowledgment he sought from Claude. He frequently abuses and demeans her with opprobrous and vile remarks when he believes that she is trying to take someone else's attention away from him. However, Alois particularly directs the cruelty to Hannah.

In order to feel dominant, he abuses others and makes them feel uncomfortable and inferior for his own satisfaction. Though his harsh temper was evident even in childhood, his sadistic streak, bizarre promiscuity, and crude language stem from the sexual abuse that he received shortly before contracting with Claude.ДЄlois enjoys the authority of a noble, he obtains and utilizes his power sadistically. His horrific childhood, which contained no parental figures, is the likely cause of his extreme need for affection and acknowledgment from Claude. One of his few consistent traits is his attachment and dependence to his butler, Claude, whose attention he is frequently trying to attract. Alois often uses harsh and impolite language, such as 'bloody' or other swears, regardless of whom he is speaking to. However, his emotions are quite unpredictable and suspicious, fluctuating from enthusiastic and hyperactive to angry and cantankerous the next and he loses interest in things fairly quickly. His contract mark is invisible at all times, and is mainly only shown if Claude is nearby.ДЄlois seems to have an overall effervescent and cheerful disposition in spite of hardships and misgivings. He holds his Faustian Contract mark with Claude Faustus - an encircled, gold, and red pentagram-like shape - on his tongue. He wears a long plum frock coat, a dark green vest with black lining and a black back, a white button-up shirt, shorts, long black stockings, brown high heel boots with purple laces, and a dark grey-black ribbon tied around his neck. Alois is a young man with light blonde hair and icy blue eyes.
