Artist: Rukiana https://www.artstation.com/rukiana
Found by ReikaMae Edited: It's highly unlikely we'll ever get them through official means. Shift Up had a dispute with the artist back in 2016 and decided to stop using her works in the game. Unreleased childs were redrawn by other artists. Even some of the already released ones (such as Midas, Hebe) also got the same treatment.
