Does Sakamoto know that Nano is a robot? Nano Shinonome and Sakamoto are among the most interesting characters in Nichijou. The portrayal of daily life of a human-like AI with a condescending talking cat is something special in it's own respect, let alone Nichijou's humorous tone!



Usually, Sakamoto calls Nano 「むすめ」: "Musume", which translates to "girl" and calls Hakase as 「ガキ」: "gaki", which roughly means "kid".

However, is there any episode where Sakamoto actually talks about Nano being a robot or directly addresses Nano about it? Further, is there any incident where Sakamoto is present when Nano's hand opens up or something similar happens?

Or is it only Yukko who fully acknowledges the fact that Nano is a robot and respects her feelings throughout the series?

If not in the anime, I'm curious if it happens in the manga!
Sakamoto has had too many interactions with Nano to not be aware that she's a robot.

From an informal sense, the fact that Nano has a screw on her back is giveaway enough for Sakamoto that she's not a normal human being.  The fact that it spins often enough is evidence enough in the sense that Sakamoto has at least seen her act as a robot.

Additionally, when they first meet, her age (1 year old) belies her size, maturity and responsibilities around the house, in spite of the fact that Nano still acts a bit like a kid.  Sakamoto could infer that she's no normal human from that, too.

In spite of the fact that Sakamoto has never directly talked about Nano being a robot, he has a very gruff and overbearing manner of speech, him being older than everyone else.  He hasn't used honorifics with anyone, and has only provided the professor and Nano with nicknames, since...


   he calls his previous owner, Nakamura by her last name.
