@dafdagh / This was purchased at the venue, so there isn't a digital raw available online. The cover art is posted on the author's Pixiv if you'd like to check it out 그리고 채색은 레벨 자동 조정 구려서 그럼. 다운 받아서 레벨 조절하면 될듯
sadly with this leveling, the original shading is lost since blacks and whites got crushed. Also there are patterns coming from the scanner i think.. the images should be available via fanbox however, i managed to find one set online
