A Japanese anime series that was once dubbed as "the pokemon killer", produced by Level-5 (the same people that did
Inazuma Eleven and Professor Layton). It takes the Japanese folklore creatures (aka. youkai) and makes them into a more cartoon-ish look more suited to kids. (AND I CANNOT THINK HOW GOOD
JIBANYAN IS. They make him like
the Pikachu of the series, imo.)
May also relate to the the most inferior thing the US has ever seen, the US dub of the original anime (which ran for 2 great seasons, and the embarrassing third one exclusive to
Disney XD (US ONLY) with a new production company). This results in mass disappointment, which Japan is making them the laughing stock by having their third game in the 3DS (game is currently japan-only, but coming soon to international release) series by introducing "merican yo-kai".
Also corresponds to the worst toy line by Hasbro (which btw, is still inferior to the japanese
Bandai merch available), now selling in dollar stores for around $1-4.
