Yamada/ tayama

Tayama
Unlike Yamada, Tayama appears more neutral and usually has a bored expression. Although she seems quite expressionless, she is secretly a kind person.

Tayama
Her true self, whom she calls "Tayama," has a much cooler appearance than "Yamada" and usually wears her leather jacket, a t-shirt dress, and a white pencil skirt. Her gold earrings are clearly visible. She often appears indifferent and bored, unless Sasaki appears; then she begins to shine.

Yamada
Because of her friendly manner with customers, she appears very sweet and carefree. She is often seen smiling, and her kindness is innate, a result of her work.

Yamada
Yamada has a friendlier appearance than Tayama. He almost always wears the company uniform and hides his piercings behind his hair, pinning it back to resemble bangs. He usually smiles and keeps his eyes closed, unless he's revealing his true personality.

She's a 25-year-old Super S employee who started part-time eight years ago. As Yamada, she's demure and the perfect customer service representative; her true self (who, when introducing herself to Sasaki as "Tayama") is much cooler, sporting a leather jacket and several gold piercings in her ears. She frequents the smoking area he often goes to. Yamada and Tayama are the same person, Yamada (see the fact that she finds his short-sleeved work uniform cute) while treating "Tayama" with extreme respect and consideration (see the fact that she worries his bare stomach might be cold and gives him her jacket just in case).
