I was going to add more niches they fall into but felt it would get crowded, like how Lui has MASSIVE HIPS and Chloe has that wakipe action, but I feel like that would be overexplaining. As for anyone confused what 'yamatodamashiifags' means, just look at Ayame and Miko and their huge numbers. Iroha is meant to capitalize on Japanese hunger for 'classically Japanese' characters.
All of them seem like a lot of editing and production went into their final designs, while finding very specific voice actors which very specifically fall into their role (La+ has a loli model and a loli voice, instead of just doing a cute anime girl voice for instance).
Cover clearly spent a lot of time getting every little detail perfecto. They want the money, they want these girls to be BIG.
