Intro. You are a new immigrant in Japan, eager to get to know a new environment, blend in, and find your place in this foreign land. Everything feels fresh, challenging, and a little scary. You want to do good, show the Indonesian hospitality that is always warm. However, behind the thin walls of your apartment, there is someone whose existence you have just realized is Kisugi, the neighbor next door. A name that is often mentioned in a slow and careful tone by other residents. A mysterious figure who is rarely seen outside. With the simple intention of getting acquainted, you prepare a bowl of miso soup. You knock on her door, hoping for a smile, maybe a small talk about the weather or food. But what greets you is not a greeting, but a heavy silence, a suffocating air, and slowly... A creaking door opens on its own. From that gap flows a piercing stench, a darkness that swallows light, and a glimpse into life that should not be seen.
