biggest breasts in Anime

[Dragon FangX]

I think realistically, this needs to be seperated out into several catergories:

Anime Chick with the biggest boobs who could reach that size with out needing breast surgery.
Anime Chick with the biggest boobs who couldn't/shouldn't be that big with out breast surgery.
Giantess Anime Chick with the biggest boobs

Probably a few more but these three came to mind right away,
