Kazuma Kiryu is the longtime protagonist of Sega's Yakuza series, now known as Like a Dragon, and Goro Majima is his unpredictable rival and ally. Majima affectionately calls him Kiryu-chan, a familiar form of address that contrasts with Kiryu's serious personality. Stretched-out versions of the call became a fan shorthand for Majima's chaotic energy, circulating through gameplay clips, streams and soundboards. It remains popular because even viewers who have never played the games can read the excitement, teasing and impending trouble in the shout alone.
