In Yo-kai Watch, player character Nathan 'Nate' Adams or Katie Forester, depending on who the player chooses, is given the titular watch, which gives him or her the ability to see Yo-kai, after stumbling across and befriending the butler Yo-kai Whisper. Originally released in Japan on July 11, 2013, the game is based on the Yōkai of Japanese folklore, who are said to be ghosts and apparitions that cause mischief in daily life.
