Alois Trancy (アロイス・トランシー, Aroisu Toranshi) is the yandere to his butler Claude Faustus from Black Butler II. His real name is Jim Macken.
Alois is a young Earl with light blond hair and light blue eyes. He wears a long plum purple frock coat, a forest 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. He holds his Faustian Contract mark with Claude Faustus - an encircled, gold and red pentagram-like shape - on his tongue. His contract mark is not visible at all times, and is mainly only shown if Claude is nearby.
- A running gag in the anime is Alois trying to get Claude to dance with or pay attention to him by saying "Olé", only to end up with Claude mutely staring at or ignoring him.
- His Faustian contract is known to only appear when Claude is close to him.
- Alois is easily frightened of childish things such as the dark and being alone.
- Alois has a striking resemblance to Anthony Herzen from the Professor Layton games, and to Relius Clover & Carl Clover from BlazBlue.
