Kanami Kurosaki is a supporting character in this story who serves as the maternal aunt of the young protagonist, Yaeka Sakuragi. Her background is deeply tied to the Sakuragi family's personal tragedy; she is the younger sister of Miyuki Sakuragi, Yaeka's mother, who is hospitalized and in a coma following an accident. Before the series' main events, Kanami played a vital role as Yaeka's primary caregiver, raising the girl at a time when her father, the yakuza boss Kazuhiko Sakuragi, was unable to do so. Kanami is an adult woman with brown eyes and purple hair that is typically cut to her neck.

In terms of personality, Kanami embodies a gentle and nurturing presence. Within a narrative populated by yakuza members known for their violent pasts and intimidating exteriors, she is frequently described as a figure who brings softness and emotional warmth. Her nature is observant and understanding; she often acts as an emotional anchor for the other characters, particularly the volatile Kirishima and the quiet Yaeka. Rather than being stern or overbearing, her care is quiet and supportive, creating a safe space for those around her.

Kanami's primary motivation revolves around the well-being of her family. Her actions are consistently directed toward supporting Yaeka’s happiness and stability, as well as caring for her comatose sister, Miyuki. Unlike many characters who are directly involved in the yakuza organization's business, her focus is on preserving the domestic and emotional health of the family unit. She runs a cafe, which provides a neutral and peaceful setting where the characters can gather away from the pressures of clan life.

Her role in the story is that of a guardian and confidante. She acts as a bridge between Yaeka’s past and present, having been responsible for the girl's upbringing before her brother-in-law, the boss, reassumed a more active parental role. Kanami is one of the few people who can offer guidance to the hot-headed yakuza enforcer Tooru Kirishima. She helps him navigate the complexities of caring for a traumatized child, including teaching him practical skills like cooking and advising him on how to understand Yaeka's feelings. In this way, she serves as a mentor figure for Kirishima, legitimizing his new role as a caregiver. Her establishment is used for key family celebrations, solidifying her status as the social and emotional hub of the group.

Key relationships define Kanami's role. Her bond with her niece, Yaeka, is foundational; she provided a stable home for the girl during her mother's absence. She shares a close sisterly relationship with Miyuki, and she works alongside the Sakuragi family to support them both. Her dynamic with Kirishima evolves from a simple acquaintance to a supportive friendship; she trusts him with Yaeka while also helping him grow as a person. She also forms friendships outside the immediate family, such as with the character Rei, showing her ability to connect with others on a personal level.

Regarding her development, Kanami's arc is one of subtle but meaningful integration. Initially, she exists slightly on the periphery, having handed over daily care of Yaeka to Kirishima. However, she remains a constant presence, and the story increasingly highlights her role as the glue holding the fragmented family together. When the Sakuragi members began to drift apart following Miyuki's accident, it was Yaeka’s courage to visit her mother that helped reunite them, and Kanami contextualizes this by noting that her sister’s cheerful attitude was originally the source of the family’s happiness. Kanami embodies this legacy of quiet strength and compassion. As for notable abilities, Kanami does not possess any physical prowess or combat skills; her notable ability is her emotional intelligence and her capacity for domestic care. She is an excellent cook and runs her own cafe, using these practical skills to nourish and comfort those in her care.
