I really like it! I am glad they've kept Gouhou Drug's black&white visuals, even the cannabis makes an appearance (which is nice, I thought it had gone for good). I don't understand why they didn't include the series' logo, but the title typography looks good too.
I think the art is slowly getting back to how it used to be, it might never reach the same level as Gouhou Drug, but it looks better than the first few chapters of Drug & Drop.
Drug & Drop #1 will be released on February 4, along with GATE 7 #4 (there is going to be a campaign for it!)
