Naomi

Naomi (ナオミ Naomi?) is the waitress of the Den Liner's dining car, the setting of nearly all of the action aboard the Den Liner.

Despite her efforts, she usually serves poorly made coffee (she once put wasabi in the coffee as an experiment), though the Imagin cannot resist it. She is extremely hyper and does not get surprised easily, sticking to her belief of making only coffee. She is good friends with the Tarōs Imagin and is usually seen playing with Ryutaros. During the series finale, Naomi takes the Den Liner back from the New Mole Imagin and uses it to go into the past to retrieve Urataros, Kintaros, and Sieg for the final battle with Kai's army of Imagin.
