The "dragon-eared" people: 聾者
The "dragon-eared" people: 聾者
聾者（ろうしゃ） looks like 龍（たつ・りゅう / dragon）＋耳（みみ / ear）then 者（しゃ/person）
Etymology-wise, it seems the "dragon" part was added just for the pronunciation, not because of dragons.
It means:
"Deaf person".
That said, 耳の不自由な人（みみのふじゆうなひと / not-free-ear people）・耳が聞こえない人（みみがきこえないひと / ears-can't-hear people）・聴覚障害者（ちょうかくしょうがいしゃ / hearing disabled people） might be more common terms. Deaf people themselves prefer 聾者 - and I can see why! Who wouldn't want to be a dragon eared person? I like the character.
Leaving the dragon angle to one side, the other options presented are a bit ableist. I don't know if ableism is a consideration in Japanese society.
a bit ableist Yea, they sound that way to me, too. I'm not sure what Japanese people think.
But, either way I like the character聾!
