Contains examples of:
- An Aesop: "Life cannot be fulfilled alone".
- Blank Slate: Nozomi's eccentric behavior, (such as being amazed of trivial things like her own shadow, responding to abstract concepts such as life and death in a childlike way (smiling and saying "Hard to understand."), and mimicking other people's behavior) and seeing as she's just come to life and is essentially only a few days old
- Cloud Cuckoolander: Nozomi, which is justified, since she's just come to life.
- Hideo counts as well, albeit being a much more disturbing example than Nozomi.

- Kansai Regional Accent: Nozomi picks it up from her owner, but when asked about it, pretends she heard people speak that way in a movie.

- Not So Different: The old man in the park remarks that the human race is somewhat similar to mayflies, which isn't exactly flattering.
- No Social Skills: Barely subverted with Hideo; sure, he treats Nozomi like she's alive note , but his conversations with her indicate that he does talk to other people.

- Nozomi doesn't seem to be too bothered by the fact that she was only made to fulfill sexual desires.
- What Measure Is a Non-Human?: Oh you best believe that this trope would be on this page.
- World Half Empty: Every human being Nozomi meets is lonely and sad. The world, in fact, is empty in more ways than one: the streets of Tokyo seem strangely deserted. The emptiness is lampshaded in Nozomi's conversation with an old man in the park.Nozomi: I'm empty too.
Old Man: What a coincidence, so am I.
Nozomi: I wonder if there are more like me.
Old Man: These days, everybody is.
