Alois Trancy, owner of the Trancy Manor has become infatuated with trying to kill Ciel for his soul in order to upset Sebastian, Ciel’s butler. Alois seems to have an overall effervescent and cheerful disposition in spite of hardships and misgivings. 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. Alois often uses harsh and impolite language, such as "bloody" or other swears, regardless of whom he is speaking to. One of his few consistent traits is his attachment and dependence to his butler, Claude, whose attention he is frequently trying to attract. His horrific childhood, which contained no parental figures, is the likely cause of his extreme need for affection and acknowledgment from Claude. 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.

Alois Trancy’s voice is high-pitched and cute at times he can be extremely annoying.  (See above paragraph for personality.
