One is about a little girl who invented a box that has a bunch of features, some helpful some usless.
The box can do just about anything, as long as you put the right bolt in it.
The other one was about a rich girl and her butler, the girl is always thinking stuff like "if I shout p**** in the midle of class, what would happen?", then right before she does it, the butler does somthing weird and ether stops her, or averts atention from her.
What are the name of these manga?
