Youkai Watch is a new IP in the works at Level-5, and according to CoroCoro magazine, it will be released for 3DS.
The game was shown briefly during the developer’s Level-5 Vision event in 2011.
It’s about a boy and his watch which allows him to see ghosts.
A release date and price are to be determined at a later date, but you can have a look at the magazine scan through Gematsu.
