Doria first appears during the Magypsy tea party in Chapter 1. She says a few words, but other than that, nothing else happens.
She makes her major appearance in Chapter 7. She tells Lucas how to get to her needle: you have to drain one pond filled with water, and put it in another. Lucas decides to go see Dr. Andonuts, who gives him a choice of three Chimeras to use. After the pond is drained, Lucas pulls the needle, and learns PK Love β. Doria disappears shortly afterwards, and leaves her memento, a Razor and Lipstick.
