Akihabara Dennou Gumi Patapi!

A young girl named Hibari Hanagokanei is very excited about the idea of owning a patapi mascot, a popular toy similar to Tamagotchi. She often dreams about a boy she refers to as "ojiisama." After an older man tells her that her prince is in a nearby hill, she rushes there and discovers a patapi mascot landing in her arms. She believes this confirms her prince's existence and that he has given her a gift. However, a large-breasted woman attempts to take the patapi from her, at which point it transforms into a Diva.
