Nate and his classmates go into the hills to do a tree planting, but they can only talk about their favorite new anime Professor Vacant. When they find a mystery, they begin to try to solve what has happened just as Professor Vacant would. Meanwhile, Jibanyan and Whisper believe a Yo-kai is involved and plan to discover it on their own. (Source: Wikipedia)
