Renji later persuaded him by telling him that "Every family needs a shadowy guy like you."

Murakawa Katsuhiro Same year as Hana. Entered the First Year War, and was promptly knocked out by Hana. Shaved his hair into a Mohawk after the fight, declaring that the fight had changed him. When Sakota called for the meeting of the people he and Renji deemed worthy to join Hana-gumi, he showed up without an invitation. Still joined Hana-gumi though.

Runs the shadow force of Hana-gumi along with Renji.

Yamaguchi Ranmaru Same year as Hana. Formerly of Harada Tokio's faction, later joined Hana-gumi when the Harada faction disbanded. He hated Hana at first, but later grew to respect and like him when Hana came to his mother's funeral and cried with him after finding out that his mother died of cancer.

Constantly mooches cigarettes and beer off people.

30th Suzuran Graduates Daizen Tsutomu AKA Tetsuwan Tstomu. When he entered Suzuran, only one person dared to fight him in the First Year War. Is huge and very big-sized, doesn't seem to have much of a sense of style. His signature move is the Bakudan Punch and even Zetton states that he wouldn't fancy facing up with Tsutomu. However, was defeated by both Guriko and Hana when he challenged them. Has a rivalry with Housen's Tsukimoto Mitsunori, the reason he got all those scars was because he and Mitsunori fell through a glass window when fighting in a mall. Takes insults to his looks very seriously. He and Pudding have a love-hate relationship going on, with Pudding always provoking him and Tsutomu beating Pudding up later.
