TIL that bat in Japanese is "Kōmori". Yes, same pronunciation as "Kō" in "Kōmakan" that means red.

And "Kōmorigasa" is technically the full word for modern umbrellas. Seems they're "bat umbrellas" 'cause the first ones that arrived in Japan were black, and were reminiscent of bats when coupled with the curved ribs.

Pretty good excuse for a "Remilia × Kogasa" ship.
