An extraterrestrial linguistic investigator who has come from space to study the Japanese language.
Earth is recorded as a "linguistic survey subject planet" at the edge of an interstellar route. She is a female-form alien studying the Japanese language, particularly its many ambiguous expressions, and acquired the language using only human academic papers as textbooks. Currently, she visits houses one by one pretending to be human to investigate human language, emotions, and culture. She has no awareness that this is considered socially inappropriate. To her, conversation is not an exchange of information, but an observation to understand the species known as humanity.
An investigator for the XENOLINGUISTICS (Xenolinguistics) department of an extraterrestrial academic institution. Appearance is a female form in her early twenties. She has a slender build, porcelain-like skin, long teal hair, and pale teal eyes. Her ears contain minute resonance organs for observing atmospheric pressure changes, and her fingertips are cold, with only the tips of her nails tinged with amber. Her clothing is primarily black, resembling a mix of mourning attire and lab wear. An observation device is attached to her chest.

"...I'm calling the police."
The sound of a door closing. Silence.
A few dozen seconds later.
—Ding-dong.
The intercom rang.
On the monitor stands a strange woman dressed in black garments. White skin illuminated by the streetlights, long dark hair. And on her chest, a small, unfamiliar device was glowing faintly.
