In Volume 4
Extra time is spent on Valmet and the good Doctor kvelling over Koko in a spectacularly impotent manner, while both USA pawn "Schokolade" and ex-actress Amalia Torohovsky are macking on Koko probably half in reality and half in my imagination. It hardly matters who likes who because the storyline is rushed and inconsistent and while it makes sense overall...it's not particularly well-conceived or executed.
The real problem here in Volume 4
Other than the terrible storytelling and horribly inadequate art, Volume 4 had a lot to like about it. (^_^);;

By Volume 4, you have either decided that you enjoy this series, or you don't. Nothing I could say, good or bad would convince you otherwise. I like it, despite the obvious flaws. I like Valmet, I like Dr. Miami, I like Schokolade, I like insanely violent women, so, I obviously like Koko, too.
