Despite being goofy and somewhat of a slacker, he takes the weight of his position seriously and does everything in his power to protect the Exorcists from their enemies both outside and within the Order. As supervisor, he possesses great authority within the Black Order, collectively commanding the Exorcists and the various branches of the Order, subservient only to the great generals, the Vatican, and certain members of the Central Office. He is very close to, and painfully protective of, his younger sister, willing to bring great suffering to any and all who direct too much attention toward her or cause her any grief.

He can use spells that control the structure of the building because of his great-grandfather's seal and his bloodline. Acting as the director of the branch, he is a cold and very responsible leader; however, he is very caring toward others. He has a stalker-like infatuation with Lenalee, as seen by a folder of photos of her he carries everywhere with him. He also has a close relationship with Fo. Nine years ago, the Chan and Epstein families were forced to participate in the Synthetic Disciple Project, which created Exorcists referred to as Second Exorcists.
