Yo-Kai Dictionary (2021)

Yo-kai Daijiten (translated as Yo-Kai Dictionary or Yo-Kai Medallium) was a planned spin-off application first unveiled in 2015. It was officially canceled in 2021. It was part quiz-RPG, where the player could answer questions based on Yo-kai in the form of a battle. And part compendium, where the player could read up facts about different Yo-kai.
