Aisaki Emiru (愛崎えみる?) is one of the five main Cures in HUGtto! Pretty Cure. She is one of Nono Kotori's classmates. She tends to end her sentences with "I say!" (「なのです!」 "Nano Desu!"?) to emphasize any point she makes.
Emiru's alter ego is Cure Macherie (キュアマシェリ?) and she is known as the Pretty Cure of Love & Singing.
I know there's a few of these but none of them seemed particularly well-organized, so I'm taking a crack at it. Costumes these characters canonically wore is strongly preferred but ig I can't really stop you if you add headcanons.
