Capitalization
For the Legendary Cooking Utensils or Dark Cooking Society, I wonder, are they really titles or more like descriptors? In the latter case I think it would be lowercase. After all, the Japanese and Chinese this is based on do not use capitals I think, and neither are actual official names or entities.   

Anime sequel?
The anime left off with many of the utensils not found, the masked member of the dark society not met (yet he was in one of the opening sequences and in Fei's flashback in the last episode), nor the leader confronted, so it seems like they left it open for continuation but didn't? Did the manga conclude the story?
