Momijigari (紅葉狩り) is the Japanese tradition of visiting areas where leaves have turned red in the autumn. The word comes from the two Japanese words momiji (紅葉) meaning "red leaves" or "maple tree" and kari (狩り), "hunting". It is also called kōyō (紅葉).[1] "Kōyō" is another pronunciation of the characters for "momiji". In Hokkaidō another word for it is kanpūkai (観楓会).

Protogens (/ˈpɹoʊ.toʊ.dʒɛn/, /ˈpɹoʊ.tə.dʒɛn/) are a regulated species based on primagen. They are more open than primagen in that anyone can create protogen characters, but they are still limited in that certain design features are not allowed. These features are disallowed as they would make them look too similar to primagen. Protogens may not be hybrids, and they must be bipedal.[1]

Protogen are shorter than primagen and have smaller, more rounded visors. Their visors are made of very small machines which can effectively chew food which is then swallowed. Protogen have working digestive systems, unlike primagen. They are stated to be earlier prototype creatures which were eventually modified into the primagen.
