>>11845041Toriyama hadn't "drawn like Toriyama" since 1998. His art style became a hybrid of the more rounded Dragon Ball style and the "everyone is a collection of right angles" late-DBZ style. You can already tell he was making the transition in DQ7.
I imagine when you're drawing your country's most popular comic AND doing art design for its most popular video game at the same time, you basically have to draw everything the same.
