Imagine the Maze, the Magic Lamp - S1.E16

The Special type class has set up their RPG maze game for the festival and are ready for costumers! Sadly nobody seems interested until Narumi, Natsume, Ruka, and Sumire come. Ruka, Narumi, and Sumire all fail, but they get other people interested in it, and soon there's a huge line! Natsume provoked by Tsubasa enters the maze and ends up winning. The winner may pick a lamp from the prize table. The lamps belong to each member of the special types class and the person who's lamp is chosen will become the winner's slave. Natsume in order to get revenge on Tsubasa tells Yome to find out which one is his but Yome misunderstands and Natsume ends up with Mikan's lamp.
