Kimito, a commoner, is kidnapped by the Japanese nobility to be a "shoumin sample," or commoner sample for a school of the children of the nobility, taught in a school cut off from the outside world. The only blessing problem is that it's an all-girls school.
The story works the best with character development amongst its harem cast. Aiko and Karen become more confident as the story goes on through their arcs, a treat to see. Seeing these rich ladies be near-humilated by Kimito's basic knowledge of the commoner's world gives an almost revolutionary feeling, seeing the nobility's social standing gives them unimaginable wealth the masses can never achieve. These chapters are quite funny, in particular the various fads introduced by Kimito on accident.
Romance development is weak. Despite the many girls circling around Kimiko, their love for him feels more out of the curiosity of commoner's culture rather than genuine romance. Only two characters have what one can call genuine love for Kimiko, even if the other characters superficially love him. Of these two its made obvious who will win. This conclusion is not a problem given the shallow love most other characters have for Kimito, but it is very predictable.
Regardless of the romance problems, the harem and comedy more than make up. Its not a great series, in particular with a lackluster ending, but remains good in its own right.
7/10.
