Shiina shared her proto design (again) and I just wanna say, we were robbed. IDK why but her rendition looks better for me, maybe it's the proportions, or the face (not really a fan of Yuuki Hagure's work here). She also reported her "cutlets" were nerfed with each new model adjustment.
She was originally intended to be a swan themed vtuber, even got sakana's approval. But when the time came Sakana said he forgot he green lit the idea and changed his mind.
