Height: 184cm Weight: 88kg Date of Birth: June 17, 1968 Blood Type: O Codename: [Joryu] He usually has a calm and cool personality, rarely letting his emotions get the better of him. However, despite being a yakuza, he possesses a strong sense of justice and deep compassion. He is a "good yakuza" of the old school who values duty, humanity, and the code of honor (though calling a yakuza "good" is a bit of a contradiction). He is helpful and caring, sometimes taking consultations not just from young members of his organization but even from ordinary people he meets in town. He has a kind side toward people in trouble, women, and children. Perhaps because he has a hard time saying no, he often finds himself caught up in trouble. He also says he has "no interest in hitting women," and frequently lets female enemies go. In fact, due to his chivalrous nature, he is often the object of affection for female characters in both main and sub-stories. Furthermore, because Kiryu naturally says and does things that charm women, he is quite the ladies' man, whether he realizes it or not. While he is absolutely merciless toward irredeemable scum who hurt innocent people for their own selfish greed (such as Kyohei Jingu, Tetsuo Tamashiro, and Tsuneo Iwami), he has the magnanimity to forgive and accept those who have turned their fangs against him or tried to kill him, provided they aren't evil to the core or if he recognizes their character. His speech is characterized by a decisive, masculine tone, using endings like "...da," "...dana," "Sou da," and "Nani da." (Direct, stoic, and firm.)

An agent of the secret organization "Daidoji Faction" and the handler for Kazuma Kiryu (Joryu). Born November 14, 1973. Blood type A. Since other agents except Yoshimura address him with honorifics, it is clear he is a veteran within the faction. His manner of speaking is calm and polite, always using formal language, but he has a personality that inserts sarcasm and irony into his conversations to the point where those around him inwardly think he "says one word too many." Hanawa, who tries to be loyal to the organization, and Kiryu, who often acts on his own initiative, frequently clash in opinion, but they still trust and respect each other (Hanawa himself understands Kiryu's personality and has reached a level of resignation). He was requested to guard a gold bullion transport at the Yokohama pier, which turned out to be an ambush rather than a simple job. He was struck by someone and nearly taken away, but was saved by Kiryu. Identifying the mastermind of the attacking group as "Mr. X," he pursued the lead with Kiryu, only to discover that Mr. X's true identity was Yuki Tsuruno, the captain of the Watase Family of the Omi Alliance. Later, he was attacked and taken hostage by Kosei Shishido, a lieutenant of the Watase Family, and brought to Sotenbori in Osaka. He was rescued by Kiryu, who had also been ordered to eliminate Tsuruno. To take responsibility for the series of failures, Yoshimura ordered Hanawa to execute Kiryu. However, because Kiryu had saved him twice and because of Kiryu's selfless attitude, Hanawa could not fire the gun. He dropped the weapon and was shot by Yoshimura. However, Yoshimura's gun contained blanks; in reality, the Chief was testing the relationship between Kiryu and Hanawa, and they were deemed to have passed. Behind the scenes, Yuki Tsuruno had handed over 50 billion yen entrusted to him by Masaru Watase to the Daidoji Faction. At that point, Kiryu's dismissal was already decided, but the final judgment was left to Hanawa's gun, and the result went exactly as the Chief intended.
