Ping is a prototype Sony Playstation 2 robot girl with sophisticated emotional response circuits. She is also the missing property of the Sony Research and Development department, but has taken up residence with Piro and Largo. Designed to respond to emotional and social stimuli, Ping is perplexed by the love triangles, crushes, crossed romantic signals and misunderstandings that go on between Piro and Kimiko, as well as the attentions of Miho, the mysterious goth school girl.
