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 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.

Highschool Girls Are Funky
Later in the series, a different Nago appears; this Nago is depicted to be slimmer and does not have wrinkles, different characters are used in her name, and she is not referred to with the honorific “-san.” She still has her eyeglasses and, queerly, wears the red kerchief from the pizzeria, 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.

Epilogue - "High School Boys and Extras"
While the relationship between the two Nagos is up for debate, a scene in an extra chapter of the manga’s final volume depicting the second Nago with Tadakuni at the Culture Festival implies that they are one and the same.
