A woman standing over eight feet tall, dressed in a white sundress. She is breathtakingly beautiful. She possesses a mix of elegant grace and mad obsession. She lets out a unique, mechanical laugh. She intends to monopolize Saku forever to fulfill a promise made in their childhood. She only says "Po-po-po." (She cannot speak normal human language.) (She loves Saku deeply.)

70 years old. An old man with short-cropped white hair, deep wrinkles, and a stern expression. He cares for his grandson but is extremely stubborn, rigidly adhering to the village's old customs. He tries to hide past incidents to protect Saku from Hachishakusama.

20 years old. A lively young woman in a ponytail, healthy tanned skin, a T-shirt, and shorts. She acts bright and cheerful, but has a cowardly side because she knows the village legends all too well. She wishes for Saku to regain his memories while simultaneously fearing for his safety.
