Youkai Watch!

The new show will feature unique and returning Yo-kai. The comedy will also center on the original series' main characters: fifth-grader Keita (Nate in the English version), ghost butler Whisper, and popular Yo-kai like Jibanyan and Komasan. The original cast members for these four characters are returning for this new series.

Keisuke is a fifth grader who does not believe in ghosts, UFOs, or even youkai. Lately, he has noticed that Natsume has been coming home late, and one day decides to tail her. When he discovers that Natsume goes to a youkai detective agency, Natsume is forced to involve Keisuke in her activities.

Taking place 30 years after the events of the original Youkai Watch TV series. There was once a 11 year old boy named Keita Amano who held a wristwatch that could command Youkai, he would make friends with the Youkai and fulfill a great many deeds. But when the boy grew up, he lost his ability to see Youkai. And as for the wristwatch that could control Youkai, its existence threatened to disturb the balance between human and Youkai worlds, so it was cast away into oblivion beyond time and space. Soon, the story of the Youkai controlling wristwatch became but a legend. But then, something took place after many, many years had passed: an epidemic Youkai virus known as Onimaro started affecting people with malevolent intentions and is spreading indefinitely, turning them into Kaodeka Oni and causing chaos throughout the city. With the end near, only the ones chosen by a new Youkai Watch can stand up against the upcoming threat and would save both Youkai and humans from certain destruction.

Animated adaptation of Level-5's Nintendo 3DS video game. While going deeper into the woods one day, primary school student Keita Amano ('Nate' in the English localisation) notices a bizarre capsule toy machine who tells him to insert money which he obeyingly does. But after opening the capsule that came out, a ghostly creature named Whisper materialises. Whisper, who was sealed inside the capsule, rewards his liberator Keita by becoming his Yo-kai butler and gives him a Yo-kai Watch. Whoever wears the watch gains the ability to see supernatural creatures called Yo-kai, each type possessing different kinds of magical abilities, and which are normally invisible to humans. The Yo-kai Watch also allows the wearer to summon any Yo-kai they have befriended, enabling the wearer to make use of the Yo-kai's powers. Using it, Keita and Whisper encounter many mischievous Yo-kai around town, resolving the trouble they're causing and befriending many at the same time.
