GATE 7 #3 cover

CLAMP-NET.COM has posted the cover of GATE 7 #3:

It will be released on May 2nd.

I think it’s safe to assume that every cover will feature Hana and an animal. I wonder if there are any meanings in the order they appear?

This illustration reminded me of one of the illustrations that CLAMP drew for the Oshiroi Chouchou book.
