BiCute Bunnies is where the BiCute family began. FuRyu frames it as a large-format series that aims for cute charm as much as sex appeal, built on volume and a rotating set of themes, and in practice that means anime heroines and originals in bunny-suit styling at a generous size. It opened in December 2020 with a Hatsune Miku in a white bunny outfit, the figure that effectively launched BiCute as a brand, and ran on through Super Sonico and a widening cast.

It is the anchor the rest of the family branches off, the gothic BiCute Dark, the soft BiCute Pure and the ribbon-themed BiCute Ribbons all playing variations on what Bunnies established. These are FuRyu prize figures from the crane-game channel, and the bunny line keeps going, new heroines and a reverse-bunny take scheduled into 2026.
