Shinko-chan (しんこちゃん Shinko-chan) is a strange girl from the future with the same facial features as Shin-chan. She has a slightly creepy demeanor, but is the opposite of Shin-chan in many ways as she is tactful, empathetic, and sees the good qualities in the people she meets. Himawari treats Shinko as her best friend, possibly due to the fact that she is Hima's future friend (around the time when Hima is 5). She is supposedly rich, having servants and owning time machine to go back to time when Shin was 5. Her coming is always heralded by dark clouds in the shape of coiled feces.
She has appeared only in the anime and not in the manga. Her first appearance was in episode 651-2.
