Jennifer Grey

Jennifer Grey, or Jenny, is the FBI's Special Infiltration Agent and a master of Guns and serves as an ally during the DofD Tournament towards Ryōzanpaku. For her age, Jennifer is a strict and serious young woman. She can also be intimidating, such as demanding Kenichi and his friends to stay out of the way during her investigations and pointing her gun at them. However, she does have a childish side, such as demanding (while sobbing) from Sakaki over why Shigure was with him and rolling around while doing so. Jennifer is in love with Shio Sakaki, claiming that she is his fiance, when in fact he claimed that his "love" for her was because he was drunk and didn't know any better. She also becomes jealous when she saw Shigure with Sakaki, threatening him with a gun for "infidelity". Nonetheless, she respects him enough to let him choose what he wishes to do, as she chose to let him leave after the tournament ended, seemingly moving on from her love for him. Like her father, she is affiliated with the Katsujinken and uses the codeword "angel" to voice the action of her plans. Unlike her father, Jennifer isn't above using her guns to kill somebody, as seen when she angrily shoots the fake Fortuna.
