A crossover of several Circus games. Your goal is to choose a partner and win the board game, where you can dress your girl, participate in the mini-games and improve her stats to beat all the opponents in the various competitions like cooking, singing, tug-of-war, etc. To clear the route, you have to comply with two conditions: 1) the relationships with your girlfriend should be at their peak; 2) you should take the first place in the competition.

The protagonist Shinichi Hirose is peacefully attending a perfectly normal school when his world suddenly becomes upside-down. Just as in the game it's based on, an angel studying at a special angel school descend to earth to learn more about humans and love in particular. PureDream focuses on the heroines Ami, Inaho, Taeko, Megumi & Rinrin.

Just like the prequel, it's contents could be best described as omake content to some of Circus' earlier titles. This time we get to see characters from D.C. ~Da Capo~, Aries PureDream & PureLove and Sukumizu ~Fetch ☆ ni Narumon!~, each chapter of the game focusing on one of the titles above.

This is the first title by STELLA, a separate brand created from CIRCUS. A thousand years ago, the legendary hero defeated the maou. Now his descendant Masamune begins his own path towards becoming a hero, but then a girl with a great sense of justice wanted to become his disciple. However, she is the descendant of the maou! She creates the ‘Brave Rangers’ (i.e. student council) and drags him along to the dungeon to defeat evil. [From [url=http://omochikaeri.wordpress.com/2011/05/18/may-2011-eroge-releases/]Hau!
