What plant does Noel use as an umbrella/parasol? There is a scene in the opening (and several others througout the anime) where Noel is using a huge leaf as a sort of umbrella or parasol.

Is that plant a real one? What plant is that?
I have not seen the anime, but I know of a couple big-leaved plants that grow in Japan. Here are three genera with links to Google’s image search:


Farfugium sp. (ツワブキ tsuwabuki), especially F. japonicum
Hosta sp. (ギボウシ gibōshi), several big-leaved species native to Japan
Petasites sp. (フキ fuki), especially P. japonicum


And then—of course—there exist many more species with big leaves similar to the one depicted in the question. It all comes down to whether the designer based the ‘umbrella’ on real-life plants or just relied on our perceived perception of an umbrella-like plant.
