'Girl from nowhere' is a show where a strange girl named Nanno goes school to school exposing people by putting them in situations where they tend to act badly and punish them for their mistakes.
The situation may vary from innocent girls who are pushed to the limit via Nanno's manipulation or just cruel people who get what they deserve.
It's interesting to see what problem certain schools have and what Nanno does about it, for example, an episode with a school that enforces strict gender segregation rules, and, well you have got to watch the show yourself to see what Nanno does about it.
What I think is interesting about this show might be how people react to the amount of pressure put on them and what disturbing things they will do to come off as innocent in the end, and maybe the sweet taste of revenge when someone gets what they deserve.
