Japaner scheinen solche Schönheitsfehler reizvoll zu finden, seien es Augenklappen, dieser spitze Zahn, der aus dem Mund guckt. Ich hatte dazu mal einen kleinen Beitrag gelesen.
Genau die Stelle meinte ich:
"While moe is about many things -- the large, expressive eyes, the impossibly cute hair and hair accessories -- to me it's all about the character imperfections that become what the Japanese call "charm points." Whether it's the extreme dojikko clumsiness and meganekko glasses of Homura from episode 10 of Madoka Magika or the extreme shyness of Mio from K-On! or even the realistic boredom and melancholy of Suzumiya Haruhi, the "defects" in the characters are what really make them interesting. A variation of this is "bandage moe," the odd cuteness of girls who are injured, with casts and possibly IV drips in their arms, or the ever-popular eye patch moe."
