Kazuhiko Sakuragi commands the Sakuragi yakuza family as its head, a central leadership role at 37 years old. He possesses brown hair and brown eyes, stands 1.79 meters tall, and was born on October 5 with blood type A. Married to Miyuki Sakuragi, they share one daughter, Yaeka Sakuragi. Miyuki remains in a coma from a car accident predating Yaeka's lasting memories. Kazuhiko exhibits profound devotion to his family, channeling fierce "Papa Wolf" protectiveness over Yaeka—reacting aggressively even to a fellow yakuza boss's joke about borrowing her. Despite his reserved, stoic nature—a trait mirrored in Yaeka—he openly displays affection and concern for his daughter. Leading with unexpected fairness amid authority, Kazuhiko earns the "Benevolent Boss" title by balancing firmness with understanding. He permitted key member Toichiro Aoi to leave the organization when Aoi's pregnant wife suffered stress from yakuza life, prioritizing family needs. In a strategic move, he assigned his most violent enforcer, Toru "Demon of Sakuragi" Kirishima, as Yaeka's full-time caretaker. This dual-purpose decision ensured his daughter's safety while attempting to temper Kirishima's brutality through responsibility. Beyond yakuza duties, Kazuhiko practices ikebana, traditional Japanese flower arranging. This interest sparked his initial bond with Miyuki during her florist days. Flashbacks reveal his contemplative side, such as pondering a sakura-patterned rice bowl intended for his child's future solid meals, reflecting his hopeful anticipation as a father. His history with Kirishima transcends boss-subordinate dynamics; Miyuki once acted as a mother figure to the young Kirishima, forging a complex, longstanding bond. Kazuhiko maintains a respectful but firm relationship with his sister-in-law, Kanami Kurosaki, who cared for Yaeka before Kirishima's babysitting role began.
