Daisaku Kuze, a high-ranking lieutenant in the Dojima Family from the hit game Yakuza 0, became an internet icon due to his relentless pursuit of the protagonist, Kazuma Kiryu. Despite being defeated multiple times, Kuze’s refusal to stay down and his iconic theme song, 'Pledge of Demon,' solidified him as a symbol of gritty persistence and old-school toughness. In meme culture, his image—often accompanied by his signature biker helmet or menacing snarl—is used to represent an unstoppable force, a recurring problem that won't go away, or simply the hype of a legendary boss encounter.
