Little saviors

Exploration Stage: Cherry Tree Spring
From: Mirai Furukawa
Description: The next method of purifying the masks was to prepare a katashiro. By having these paper dolls absorb evil spirits and burning them, we were supposed to be able to dispel evil. However, the moment we set it on fire, it was blown away by a strong wind. Could you help me find it?
Completed: This is the form factor I prepared. But something is wrong... the fire that is burning is green and unnatural. Moreover, it cannot be extinguished. It's as if the evil energy that the katagayo drew from the mask has been absorbed again. No matter what I do, it has no effect. And the spirit is still there.
