Or 1998-2001 Early Works. I've been a fan of Junko Mizuno's art for a long time and came across a puffy, sparkly cover of this book. It may be the coolest book I own!!!
In these early works, the only difference I see is less detail and not so much trippy backgrounds. It's fun, brazen, naughty; sometimes gorey, sometimes fetishy, but above all, cute. Like, so, so cute.
