Shitai-san (死体さん, 'Mr. Corpse', pronounced more like "shee-tai" in regular speech) is a character found in Madotsuki's dreams.
He is found on The Road section of Dense Woods B surrounded by traffic cones. Interacting with him gives you the Stoplight effect. It symbolizes a traffic incident due to reckless driving.
Using the Cat effect near him causes him to twitch.
- Unlike all other Effect NPCs, Shitai-san is the only one to not react on the Knife effect.
- Shitai-san is one of the more popular NPCs in the Yume Nikki fandom.
