Nobita and his friends get transported to an animal planet after a mysterious pink fog appears inside his house. They work together with the natives to find the origin of the fog.

As Nobita, Shizuka, Gian, and Suneo are auditioning for a role in their school's play based on "Journey to the West", the coveted role of Son Goku is hotly contested. After suggesting that the real Great Sage Equal to Heaven should play himself, knowing that the story is only a legend, Nobita and Doraemon go back in time to find their own fake Monkey King, but arrive in present day with the story's demons having taken over the world. The only way for things to go back to normal is for Nobita and pals to reenact the tale...for real!

“虫”既不是动物，也不是微生物，而是一种自然界中无处不在的力量，拥有独特的生命形态，偶尔和人类生命产生交汇，便生出一些奇妙的故事。但人们即使得知了“虫”的存在，大部分时候也不知如何应对，这便需要“虫师”出马。
银古就是一位虫师，他一头银发，年纪尚轻，但已经半生游历，经过一个个山野、村庄，为人们解决“虫”的问题，通过和被“虫”困扰的人们接近，他也接近了许多故事。银古的游历像风一样，再惊心动魄的“虫”似乎都融化在水墨样的山峦叠嶂间，芸芸众生也是过眼云烟，淡淡的故事里没有哀伤只有静穆。

Due to an unusual ability to see strange creatures called youkai, Takashi Natsume has never fit in. Over time, he has accepted that no one would ever believe him and has closed himself.

When Natsume accidentally breaks an intangible barrier, he frees Madara—a mighty spirit in the form of a lucky cat. Madara notices that Natsume bears a remarkable resemblance to his late grandmother Reiko Natsume, an outcast girl who created the Book of Friends. It is now in Natsume's possession.

With no interest in its powers, Natsume decides to keep the book for the sake of his grandmother's memories and to protect it from scheming youkai. Therefore, he makes a deal with Madara: he will hand him the book once his time is up, and in turn, Madara will act as Natsume's unofficial bodyguard. With his newfound goal of freeing those Reiko had sealed, Natsume's relationship with both youkai and humans slowly begins to improve.
