Hiro and his friend Ren Machino refuse to believe Aya's tale of the Sly Girls, who are an urban legend in the city, but Ren, who designed Moggle, agrees to help Aya retrieve him. Aya also happens upon a story about Frizz, discovering that he started a clique based around a brain surgery called Radical Honesty, which enforces honesty and makes a person unable to lie.
