Matsuzaki, Ginji

松崎銀次

Ginji Matsuzaki serves as the acting wakagashira (underboss) of the Washimine Group. He currently works as a street stall vendor, though he was formerly an assassin known as "Hitokiri Ginji" (Manslayer Ginji) because of his use of a katana in combat. His proficiency with the weapon is exceptional, demonstrated by feats such as cleaving bullets in two midflight. Combined with his ability to dodge gunfire from multiple opponents, Ginji almost entirely avoids using firearms.
Ginji protected Yukio for a long time and hoped she would live a normal life despite her family's criminal background. He appears to regret his past as a murderer, yet he is willing to take up arms again for those he cares about. He is killed by Revy in a prearranged duel after he and Yukio realize they cannot defeat Balalaika and the rest of Hotel Moscow.
It is worth noting that although Revy calls Ginji "Jumbo" due to his height, the name "Jumbo" may also refer to Takeshi Takeda (AKA "Jumbo") from the Yotsuba&! manga series, with whom he shares an uncanny resemblance.
