that pic lmao.
About lewd fanart I have already (partially) answered you before.

most artists want to make money (with patreon or other shit) so it's obvious they use popular characters, erza and lucy (in the case of fairy tail) when a secondary character is drawn (like pic rel) it means she's popular in the story (and therefore there''s demand; but that was never the case with levy) or that the artist drew something therefore the editor also wants to attract attention by exploiting the original artist) like picrel
