Halibel aint got such dark skin bruh. She has a darker tone to her, but its more like a tan.
Why I know such a thing ?
Strangely enough, from all the possible shows, games, etc I ever played, she is what I would consider the most a Waifu~fufu (or a Waifu candidate, though not the only one granted.)
Plus I got a small PVC figurine of her on my shelf.... yeah I suppose waifu confirmed mofu ! :3
Even I find it funny since she had a very little screen time and her role was not that important all things considered, but as far as Bleach is concerned she is my fav. character
