Simetra, a world where 12 bestial species in a humanoid form live and work together in supposed harmony despite their food chain levels. For some uninvestigated reason, these 12 species happen to be of those from the Chinese zodiac. Ever since the New Peace Order, all matters of conflict pertaining to specific differences have been dissolved. The order is an attempt to equalize the food chain, drafted up by the Dragon's oligarchical government. Despite this effort, the food chain still simmers underneath as racism runs abound.
