Yume Nikki Wiki

Onsen-san (おんせん-さん, Mr./Mrs. Hot Spring) is a strange character that can be found in the Hot Spring House in the Wilderness. Its appearance can only be seen by using Lamp effect because of the darkness of the house. Onsen-san is sitting beside a hot spring pool and has a cord from its head absorbing the spring water.


Its appearance in YUMENIKKI –DREAM DIARY–


It reacts to the Knife effect and the Stoplight. Using the Knife on it will change the color of their head from red to blue and it will no longer imbibe the spring water, as if it has died. Using the Stoplight will stop it from drinking more water when it's alive, but it is hard to see that due to the dark.
