Nago

Nago is a student at Sanada Central High and a co-worker of Tadakuni and Yasunori at Pizza-Le.

Appearance
Nago has brown eyes, medium-length black hair and wears rounded rectangular eyeglasses. She is rather tall and plump, and is depicted with wrinkles on her face in the manga. At work, she wears a red kerchief as a bandanna and removes it when she's going home.

Personality
Nago is generally reserved and composed. She is a fastidious worker who sometimes gets annoyed by her male co-workers’ narcissism but doesn’t fail to humor them once in a while. She acts as a confidante to Tadakuni and gives him advice, sometimes getting exasperated with his self-conscious behaviour.

High School Girls Are Funky
Later in the series, a different Nago appears inside Central High. This Nago is depicted to be slimmer and does not have wrinkles, and different kanji characters are used in her name. She still has her glasses and, queerly, wears the red kerchief from the pizzeria in school, which the first Nago removes outside work. Going to the same school, Yanagi considers her as a rival in academics and skills and challenges her frequently. Despite not knowing who Yanagi is, Nago humors her challenger and surpasses her in every aspect.

Nago's pizzeria avatar does not make a return in the series after the second avatar's appearance.

Epilogue - "High School Boys and Extras"
While the relationship between the two Nagos is up for debate, a scene in the epilogue of the manga depicts the second Nago with Tadakuni at the cultural festival, implying that they are one and the same.
