Eri Minami

First seen with Yu at a park, Eri developed a connection with him during the Summer Festival watching fireworks. A significant moment occurred when she apologized to Yuuta's mother for his behavior, leading to a revelation about his parentage. A tense interaction with the Kaneko's mother escalated, resulting in Eri intervening to protect Yuuta and sustaining an injury. Afterward, a moment of reconciliation followed as she regained Yuuta's trust.
