Sayaka is laid back and friendly as a nurse/teacher. But that respectable and gentle image disappears once she starts drinking. The alcohol reveals a totally different personality, that of a drunken lady, who uses the Embankment Club as her personal nightclub. There, she can drink, eat, and talk to the girls casually. She usually shows up at the club at the end of the month to buy food, since she spent most of her salary on liquor.
