The Knight Cartoonist and Her Orc Editor v01-v03 (2019)

English translation of the Japanese manga Orc Henshuusha to Onna Kishi Mangaka-san (オーク編集と女騎士マンガ家さん).
Yeld, an orc sick of life in his dark-fantasy realm, decides to move to Tokyo and become a comics editor. One day, he's visited by a full-time armored swordswoman, part-time aspiring manga artist - one who gets practically suicidal whenever her work gets rejected! Between her, a tentacle monster summoned as an assistant, and a slime girl with all kinds of helpful manga tools, there's never been a stranger pack of creators! It's the most realistic (?) depiction of the manga industry yet!
