Hira Hira Hihiru invites you into a setting where the veil between life and death is thin, and the boundaries between man and monster are blurred. Here, in the fictional Taisho era, a chilling disease known as Aerodema is sweeping across the land. Her victims, “hihiru”, are the resurrected dead, their bodies decaying and their minds dimmed. Banished by society, they exist in a twilight realm, neither truly alive nor completely dead. Enter the position of two people caught in the heart of this tragedy. Masamitsu Chigusa, a young doctor, dedicates his life to researching aerodema and improving the lives of patients.

Takeo Tenma, a student unaffected by the disease, finds his setting shaken when it strikes a close home. Their paths converge, driven by a common desire to understand and overcome the Aerodome. As they delve deeper into the mystery, they encounter the complexities of human prejudice and ethical dilemmas surrounding the hihiru. Their journey will test their courage, compassion and understanding of what it means to be human. Hira Hira Hihiru is not just a story about illness. It is a poignant exploration of mortality, social fear and the resilience of the human spirit. It forces users to confront their own prejudices and think about the humanity that lurks even in the shadows.
