Yakuza is an action-adventure beat 'em up video game franchise created, owned and published by Sega. The series originated from Toshihiro Nagoshi's desire to create a game that would tell the way of life of the yakuza. The series primarily focuses on the yakuza Kazuma Kiryu from the Tojo Clan. While Kiryu often assists the Tojo Clan, the series has also featured him searching for another way of life in the form of raising orphans. The gameplay of Yakuza has the player controlling Kiryu (or another character depending on the title) in an open world where he can encounter an enemy or perform an activity in the city to obtain experience. Yakuza 0 is a prequel to the original game. In December 1988, many years before the original Yakuza, a young Kazuma Kiryu is framed for the murder of a civilian, leading him to be hunted by members of the Tojo clan. At the same time, Goro Majima finds himself protecting a helpless blind girl whom he was ordered to assassinate, making him a target himself. The two must each attempt to protect themselves and uncover the truth, including how both incidents are tied to the mysterious "Empty Lot".
