Like a Dragon: Infinite Wealth sees Ichiban team up with both new allies and previous friends from LAD 7, and the plot focus of chapter four places emphasis on its two additions: Tomizawa and Chitose. As Infinite Wealth introduces its new Hawaiian setting, the threats lurking within this location make themselves known. Tasking players with venturing into dangerous territory to find Chitose and help Tomizawa get back at the man who was responsible for his false imprisonment, the District Five sequence acts as the title's first dungeon of sorts, where certain effects play a part in how the Infinite Wealth team traverses.
