Shouko Hida

Shouko Hida is Sato's closest confidante and a fellow part-timer at their shared workplace. Raised under strict household rules, she developed a bright and cheerful disposition, placing friendship above all else in her life. When she began to sense that something was deeply wrong with Sato — uncovering the dark truth behind her actions — Shouko chose not to turn away. Driven by genuine affection and an unwavering sense of justice, she reached out in hopes of saving her friend. Tragically, it was this very purity of heart that drew her into a cruel and irreversible fate, leaving her as one of the story's most heartbreaking losses.
