Why do you hate dragons so badly that instead of actual dragons who can turn into dragons you add HALF-BRED ones?!
I HATE half-dragons, I need ACTUAL dragons - like Tohru, Tanya, Iris, Tio, Veldora's sisters, Eco etc!
Why is a dragon adoptive daughter's dragon form completely abandoned?
Manga itself ended at chapter 40. After defending a friend from a winged bear, a dragon never changed back since then.
Seriously - stop using human form as the way tl get rid of dragon forms.
