Nimi > Dooby >> Saba
Soggymama does good work. Straddles the line well between cutesy and subtly erotic.
Dooby is okay, distinct outfit, a lot sexier than Ame, her censorship underwear is funny.
Saba's design feels like the most shameless attempt to call back to her old persona. Like the final boss of Gura clones. Also I find the ears a weird addition for her default design, it takes away from her mackerel theme.
