Mob girls

She sees herself as a simple side character. Not as the villain, not as the heroine (she kind of tried before, but for the general majority of the series she's accepted her fate and sought to enjoy her life.) But as just someone who is "the heroine's good friend".

Unlike some of her peers, she doesn't seek friendship or love or even a high fetched dream, she simply lives as a normal otaku - unfortunately, she catches a troublesome guy's attention... (although she lives ordinarily and makes the most of her life being "ordinary", she's actually very smart.)

Calls herself "Maid A" and sees herself as part of the mob. She doesn't exude much of a presence and doesn't catch most people's attention. Her average existence gets disrupted by the most powerful hero in the world - and as such, the world's fate depends on her...

I was wondering whether or not she should be on this list because she's ambitious as far as medicine and poisons go, but then it appears that in general, she sees herself as part of the crowd, and for the most part, she is deemed as such. In fact, if it weren't for the reputation of those around her, and her strange behavior, she might be a complete mob. Hence, "mob girl".

She doesn't even want to stand out. She just wants a peaceful life with her father, never minding others and going about like that.

An unambitious idol otaku who lives in simplicity and averageness. Without noticing, she has spun a tight circle of friends around her.

Even sees herself as a mob, and relishes in that position as an ultimate observer. After seeing a ton of shy, sweet, and dreamy girls in shoujo, and a fair share of strong, I-will-conquer-the-world types, she's a refreshing character that distinguishes herself from other manga heroines during or before her story's release.
