めおと鳥 (meoto tori)
These tops are a pair of pheasants, featured together as a couple. Each of the pheasants can be removed from the base and parts of them become individual tops.
Hiroi Michiaki: This is… ah, this is a sparrow. You unfasten these, and all of them are tops. Chummy sparrows. Hm? They aren’t sparrows. What are these? They’re pheasants. Pheasants. A pheasant couple. When you take these off they’re all tops. Pheasants, too, have all kinds of stories about them.
