Yamada

The female protagonist, and a part-timer at Sasaki's regular supermarket. (Super S)

Age: 24
Birthday: February 24

As Yamada, she is calm, wholesome and the perfect customer handler; her real self Tayama is much edgier, with several ear-piercings and sporting a leather jacket.
She invites Sasaki to come to the smoking area behind the store, which he then does regularly.
