Waitress Nana-chan lives a humble life while aspiring to be a celebrity. One day she is chosen as the mascot of Oxhorn Public Company for her bust. Knowing that all their previous mascots became celebrities, she eagerly accepts. When she is asked ideas on an advertising campaign, she can only come up with "something sexy," and adds that she is willing to do anything.

"Hello, I'm Nana... The eighth Oxhorn Girl..." She heavily blushes as she wore a cow girl attire.
