Our initial idea was to create a futa figure sex doll. After we had a successful collaboration with Sinen, we have a idea of making a co-brand doll. We really like this character and discussed the concept of a co-branded product with Sinen. And so, this project was born, going through many rounds of modifications and attempts from modeling to head sculpting to body design, we finally perfectly recreated the beloved character Sinen that many people love.
