Sana

K cups, base size
Largest and heaviest of her gen, sags slightly more than Kronii's
Large pale-ish cream-colored areolas in contrast to her caramel skin, short and thick nubs for nipples
If the stars and planets align, her breasts can shift sizes and may even lactate

Kronii

J cups
Second largest of her group, soft to the touch
Pink protruding nipples with average-sized areolas
Even with the boob window, Kronii tends to build up a lot of boob sweat, especially underneath her large mounds

Fauna

I-cup
While dwarfed by Kronii and Sana, her bossom is just as plump and bountiful as nature itself
Soft, rosy pink nipples adorn her supple breasts, a faded outline circles around her medium-sized areolas
During extreme weather conditions, her breasts will begin to leak milk in large quantities in order to nurture growth after potential natural disasters

Mumei

D cups
When not hidden under her cape, her breasts are very perky and bouncy
Puffy pale-brown areolas and small flat nubs for nipples, nipples are slightly darker
Nipples get hard easily so they're are almost constantly poking out of her tops since she refuses to wear a bra

Baelz

Most modest but firm bust of her gen
Her small puffy areolas are a light pink with cute inverted nipples
Her nipples are super sensitive, becoming fully erect and visible with minimal stimulation

Omega

Non-existant breasts save for two small nipples. Very erotic.
