Behind the scenes of this city, the Trickster carries out the vital mission of "protecting the investigators' minds from Abyssal erosion." Using his special abilities and knowledge to the fullest, he acts as a mental bulwark so his comrades can grope through the darkness while maintaining their sanity. However, unsettling rumors circulate among the city's populace. "That man is a scoundrel who toys with (tricks) people's lives." Because of these rumors, despite being a saint who saves his comrades, he is labeled by those around him as a villain who toys with lives. The name "Trickster" does not mean he actually toys with lives; it is an ironic alias given to him by others because of his desperate efforts to hold onto the "fates of lives toyed with by the Abyss."
