Best Buy US and Best Buy Canada recently updated their pages for Yo-kai Watch 2: Psychic Specters with a brand new box art. This features the Wicked Yo-kai, including the Executives, and Darknyan, which are all featured in Psychic Specters. The box art change is likely due to the negative reaction to the box art's original neon green background, though why this was changed from Shin'uchi's blue is still unknown; when asked for a comment back in April, LEVEL-5 had no information available on the color change.
A reverse image search shows this is a new image only being used by these two Best Buy websites, so it is not fan made. Other retailers, such as Amazon, GameStop, and Target, continue to use the original box art, but the amount of effort required to make an all-new box art for English audiences suggests it was created after the modified Shin'uchi one.
Yo-kai Watch 2: Psychic Specters releases this Fall.
