the name popped out in forum #86653 as kaiko_(artist). 2 former posts were actually from eat. the posts were cropped versions cutting down the supposedly watermark below.
the comments on post #300565 made me doubt if the artist is really the right one.
some questions: how should i address the source fields of post #292295 and post #292294 ? should i clear them so that the pixiv account linked to kaiko_(yrn) will not give out an erroneous artist?
EDIT: i should have checked all the children first! well, it seems the real artists are eat and zhaoyebai. but a comment below post #1173566 made me unsure again.
EDIT2: thanks henmere for the informative research! comment #1141249
