The Broker is an individual who, despite initially coming across as jovial and light-hearted, is considered dangerous and manipulative. He has little to no sense of morals, instead preferring to align himself with whichever side of a conflict would benefit him more. He has a habit of stalking other Demons, particularly those who can grant him useful information. He does not appreciate other factions meddling in his business, and has a dislike for bootlickers. While he tends to talk in a friendly manner to most Phighters, it is soon apparent that he has ulterior motives in a majority of interactions, such as when prepositioning Shuriken for a job offer.

He has a particular hatred for Katana, dropping his usual 'jolly' façade to threaten Katana through the phone. Despite his typically exaggerated displays of joviality or threats of violence, he is demonstrably frightened by Ban Hammer - notably panicking when Ban Hammer is the one to call him.
 

Despite his overall demeanor, he appears to have genuine fondness for his boss, Scythe, as well as Zuka. (Credits to the official wiki.)
