Enter Sandman

Yui's an airhead; Ritsu can't stop grinning even if her life depended on it; Mio's a scaredy-cat; Tsumugi is incapable of loving guys at all; and Azusa represses an easy-going personality she once had by being an organizational tightwad. They weren't always like this, which raises some major questions: Why are they this way now? What happened to them in the past? Who/what is this mysterious "Manchurian Global"? And why are they so intent on killing Hokago Tea Time off?
