Hakuoki Yuugiroku DS

Chizuru notices some of the Shinsengumi meeting in secret and reports it to Hijikata. During her watch, she overhears Itou talking about something he lost — something that must not fall into the other members' hands. When she finds and opens the box he has been looking for, everything shifts: everyone around her is suddenly in chibi form. The only way back to normal is to clear a series of mini-games and find out what was really inside the box.
