Froot drew her model herself and worked with the riggers the whole way to make sure that the expressions and movements that came out were what she wanted. Most vtubers don't have that kind of direct artistic control, or aren't interested in it, so they don't have anything like what Froot has. Not even other VShojo members have models as well done as hers, and many of theirs are top quality.
