The story centers on a girl named Maika who gets a job at a cafe where all the waitresses are given certain attributes — such as "tsundere" or "little sister" — to embody while serving customers. The manager asks Maika to be the "Do S" (extreme sadist) waitress, so she will have to adopt a dominant and aggressive persona. (Source: Anime News Network)
