 Despite not being alive, Hiroshi-kun is treated like a living person, narrating the opening of each anime episode, and dancing during the anime's end credits.Hiroshi-kun was found by Sunako in a pile of rubbish shortly after she was described as being ugly by her first crush, and she formed a bond with Hiroshi-kun, both being "discarded" from the world.Sunako takes good care of Hiroshi-kun, along with her other anatomical friends (Josephine, Akira-kun, and Sergeant George).
