And that sets off a rather convoluted story of corporate procedures, corporate (and political!) infighting and literal backstabbing. It's almost as if the class was an afterthought, and it mostly is, except when they take a class trip to the beach and prepare for the school festival. Still, it's an interesting series with plenty of plot twists to keep things really interesting right up to the end.
I liked it. There's a hint as to a sequel, but I'm not sure I'd be up for more of this, though. The story is finished, and while there are some unresolved plotlines, I don't think this particular series would benefit from continuing.
I have noticed a trend (or trope) in the depiction of wealthy families though: they seem to get away with everything, including murder, and they have their fingers in just about every pie. This is another one of those series where the conflict within a family spills over into corporate and political manoevering. I can believe that old and influential families exist in Japan and that they are highly valued members of economic and political society, but I find it hard to believe they would actually be above the law.
It would have been cool if the scheming would have to be within legal confines, because that would have made it much more subtle. Just killing the heir's minders in order to abduct him is kinda lazy storytelling.
