Ootari Gakuen Shikkoubu summary:

From Toothpaste Scanlations: Only the rich, upper-class students get to attend the private school, Ootari Gakuen. The ordinary girl who transferred to this campus was Oogisaki Minori. Minori originally dreamed of having a happy school life, but she never thought that there would possibly be a reputative Student Enforcement Council full of cute guys, who through their strict rules, control the whole school! Not only that, but on Minori's first day of school, she was picked on by them!
