Jeryy is a good friend to the Exorcists and Finders at the order and is often a confidant and source of inspiration when the Exorcists are troubled.
Jeryy is Indian in nationality, although his family ran Muay Thai dojos. Jeryy is adept at this style of fighting and was in line to inherit his family's dojo from his father. Jeryy did not want this life though and proceeded to travel the world, learning to cook in China. After joining the order he became best friends with Komui Lee and became close with Lenalee Lee.
Jerry is briefly introduced as Allen enters the cafeteria during his first days at the Order. The Indian is overexcited by Allen's polite behaviour, although surprised at first by Allen's big appetite, soon after becomes "a fan" of young exorcist.

Rohfa sees him arguing with Bonnaire about the cooking. Jeryy insists that as he is the head chef and Bonnaire is only a finder, his opinions do not matter. Bonnaire counters that since he is here to look after his beloved Reever, it is his job to ensure he receives proper nourishment. Reever tries to diffuse the argument by saying that he isn't hungry, but Jeryy and Bonnaire insist that he needs to eat and both try to feed him at once. After He collapses and is rushed to the medical ward by Bonnaire, Rohfa asks Jeryy where Allen Walker is. Jeryy tells her that Allen had left some time ago and directs her to the science department.
