It's been a few months, normally by now they update the official website with information about the rest of the game and possibly postgame and include official artwork and such, but they haven't yet. The only thing we have is artwork of Kahili and Nihilusamine scanned from an artbook and concept sheets of Ryuki and Grimsley and Z-Powered Lillie and the other characters that weren't in the video updates.
Where's the real official art?
I want official art of Anabel and Colress and Acerola and Hapu and Z-Lillie and Mina and the rest.
