Meitantei Conan: Hanamaru na Answer

Synopsis

Jewelry stores across town are being robbed, but Conan's young friend Ayumi is excited. The crimes bear a striking resemblance to the events of a certain magical girl anime she's enjoying, and she's hopeful that she'll get to meet a "PreCure!" if the thieves show up again. Cure Answer appears in the episode, and Conan seems understandably surprised. (Source: Detective Conan World)
