Sakura Taisen 2 Unlockables

Allow the game to idle while playing the game. After awhile, the screen will darken. Wait even longer and a random SD character will run around on the screen.

Finish the game at least once and enter "A Long Day In Teito". Go into the kitchen and Tsubaki will challenge you to a trivia quiz. Answer all the questions correctly within the time limit. Upon completion, enter the attic and Kayama will challenge you to another quiz. Once again, answer all the questions correctly within the time limit. Upon completion, entering the salon will allow you to play Hanagumi Trump Taisen, the card game that was played on the bus in episode 5.
