Every time I hear or see a Japanese person talk about what they like about the game they always mention they like its, "distinctly western cartoon visuals." Paraphrased of course.
Folks here see and focus on one thing and they see another.
This is fantastic news for the company, achieving something that even far larger studios never accomplished.
Regarding the visuals, FWIW, I don't like the Skullgirls art style much because of its distinctly western cartoon style
So I wouldn't think that the Japanese like it because it's "animu".
