Tsukishima Hana is the main protagonist of the manga series Worst and a member of the Umehoshi Family. He is Suzuran All-Boys High School's first generation leader and the boss of the Hana-Gumi, who is infamous for becoming the first person to ever unite the hellish delinquent school Suzuran as one faction. He came to the city from a small town and won the First Year War. He shocked people when he declared that he wanted to become the leader of Suzuran, because Suzuran has never had one man lead the entire school before.

The only man known to fight on par with Guriko, Hana is an extremely strong fighter, who's strength is usually underestimated because of his friendly nature and lack of intimidation, always asking his opponents to not hold any grudges before they fight. He has a unique charisma about him that draws people to his side who wish to follow him, especially the students at Suzuran High and byHanaki Guriko's own admission Hana is the only man fit to rule Suzuran because men of his caliber are hard to come by in today's world. He'd fight,bleed and cry for anyone.

The Fourth and current owner of the Bullshit Buckle secretly passed down by Harumichi Bouya. One of the seven men from Toarushi who traveled to Machida Tokyo to finish the war against The Manji Empire's Manji 7 , defeating the Odaken Group's Shibaki Masami.
